The Mexican Water Treaty of 1944 committed the U.S. to deliver
1.5 million acre-feet of water to Mexico on an annual basis, plus
an additional 200,000 acre-feet under surplus conditions. The
treaty is overseen by the International Boundary and Water
Commission.
Colorado River water is delivered to Mexico at Morelos Dam,
located 1.1 miles downstream from where the California-Baja
California land boundary intersects the river. The river’s
natural terminus is the Gulf of California in Mexico, but because
of the dams and diversion facilities throughout the Colorado
River Basin, natural flow rarely reaches the Gulf. Water diverted
at Morelos Dam is primarily used to irrigate Mexicali Valley
farmland, and also supplies the cities of Mexicali, Tecate and
Tijuana.
Southern California, like most of the West, is in the middle of
a record dry season. To combat it and keep the metropolitan
area well-watered, they’re relying more heavily on the Colorado
River, with water pumped directly from the south end of Lake
Havasu. Last Wednesday, the Metropolitan Water District began
pumping from Lake Havasu at full capacity for the first time in
years, drawing water from the Whitsett Intake Pumping Plant
located just north of the Parker Dam. The eight-pump flow is
equivalent to about 3,000 acre feet of water being pumped per
day, according to MWD Manager of Colorado River Resources Bill
Hasencamp.
The White House announced the intent to nominate several
officials to serve at the Department of the Interior, including
Tanya Trujillo as Assistant Secretary for Water and Science.
Trujillo is a water lawyer with more than 20 years of
experience working on complex natural resources management
issues and interstate and transboundary water agreements. She
most recently worked as a project director with the Colorado
River Sustainability Campaign. Before then, she served as the
Executive Director of the Colorado River Board of California.
The San Diego County Water Authority is no stranger to conflict
– virtually all of its dealings over the past decade have been
shaped by its feud with the Los Angeles-based Metropolitan
Water District of Southern California. Now that feud is fueling
fights within the agency itself.
The Colorado River is one of the most highly developed surface
water systems in the world, but demand for the river’s water
continues to exceed supply. University of Arizona geosciences
professor Connie Woodhouse discusses the impact of a warming
climate on the Colorado River. She is the featured speaker for
the annual College of Science lecture series April 15. Connie
Woodhouse spoke with Leslie Tolbert, Regent’s professor emerita
in Neuroscience at the University of Arizona.
Extreme drought conditions throughout the West are lowering
levels in the crucial water reservoir, Lake Mead. Scars of long
years of low precipitation are hard to go unnoticed at Lake
Mead, and the hot, dry summers have been felt for the last
several years in Arizona. 2020 was especially dry, with little
monsoon. Now, the West is in uncharted territory. Lake Mead is
projected to drop by several feet this year, from elevation
1,083 to about 1,068, according to officials with the Central
Arizona Project. The lake is hovering around 39 percent of its
full capacity.
[T]he 800 to 900 people in Tohatchi, and another 600 to 800 in
Mexican Springs, eight miles to the west, all depend on a
single well and single pump. If the pump running it fails,
or if the water level in it drops — both issues that have
troubled nearby Gallup this year — water will cut out for the
homes, the head-start center, the schools, the clinic, the
senior center, five churches, and the convenience store and gas
station. … [T]he Navajo Nation has waited more than a
century for pipes and water treatment plants that would bring
drinking water to all of its people while watching nearby
off-reservation cities and farms grow, swallowing up water from
the Colorado River Basin that the tribe has a claim to.
The government of Mexico is on the verge of legalizing cannabis
for industrial, medical, and recreational purposes, legislation
that would make Mexico only the third country to legalize all
aspects of cannabis production and all types of the plant’s
use. … Water theft in California is alleged to be
frequently associated with legal and illegal cultivation of
cannabis. It equally pervades legal and illegal cannabis
cultivation in Oregon and Colorado.

Scientists have been predicting for years that the Colorado
River would continue to deplete due to global warming and
increased water demands, but according to new studies it’s
looking worse than they thought. That worries rancher Marsha
Daughenbaugh, 68, of Steamboat Springs, who relies on the water
from the Colorado River to grow feed for her cattle.
… Recent reports show that the river’s water flows were
down 20% in 2000 and by 2050 that number is estimated to more
than double.
South Bay officials are beginning to run out of patience over
the continued cross-border flow of sewage-tainted water. The
pollution warning signs have been up most of 2021 on the sand
in Imperial Beach. Last Friday, the pollution flowed north to
Coronado, forcing beach closures there. Imperial Beach’s top
officials are fed up.
Rainstorms grew more erratic and droughts much longer across
most of the U.S. West over the past half-century as climate
change warmed the planet, according to a sweeping government
study released Tuesday that concludes the situation is
worsening. The most dramatic changes were recorded in the
desert Southwest, where the average dry period between
rainstorms grew from about 30 days in the 1970s to 45 days
between storms now, said Joel Biederman, a research hydrologist
with the U.S. Department of Agriculture Southwest Watershed
Research Center in Tucson, Arizona.
Our two-day Water 101 Workshop begins on Earth Day,
when you can gain a deeper understanding of
California’s most precious natural resource. One of our
most popular events, the once-a-year workshop will be held as
an engaging online event on the afternoons of Thursday, April
22 and Friday, April 23. California’s water basics will be
covered by some of the state’s leading policy and legal
experts, including the history, geography, legal and political
facets of water in the state, as well a look at hot topics and
current issues of concern.
Unrelenting drought and years of rising temperatures due to
climate change are pushing the long-overallocated Colorado
River into new territory, setting the stage for the largest
mandatory water cutbacks to date. Lake Mead, the
biggest reservoir on the river, has declined
dramatically over the past two decades and now stands at just
40% of its full capacity. This summer, it’s projected to fall
to the lowest levels since it was filled in the 1930s following
the construction of Hoover Dam. The reservoir near Las
Vegas is approaching a threshold that is expected to
trigger a first-ever shortage declaration by the federal
government for next year, leading to substantial cuts in water
deliveries to Arizona, Nevada and Mexico.
The idea of cloud seeding and weather modification has been
around since 1940. There were federally funded programs in
the 1960s—one named Project Skywater that ultimately
had mixed results. In the 1970s and 1980s, the US government
began experimenting on how weather modification could be used
as a war tool. But outside of ski resorts like Vail, where the
technology is used to help increase snow during snowstorms,
interest in cloud seeding largely dropped off.
… According to the North American Weather
Modification Council, there are currently several projects
being run in California, Wyoming, Colorado, Texas, Utah, among
other states with a project here or there.
It was in 2016 that the state of California declared a
four-year drought had finally come to an end. Now, in 2021, it
could be entering another very dry season. It is in the winter
season that folks on the West Coast welcome dreary days packed
with cloud and rain. California usually sees the most rain and
snow in the month of February. This year, however, was
different: It was quite dry all of the winter season, and we
can blame La Niña for this pattern. … Thirty per cent of
California’s water supply comes from the snowpack in the Sierra
Nevada mountain ranges and only 57 per cent of normal
precipitation has fallen this season. This, coupled with lower
than average snowpack for 2020 as well, could spell trouble
down the road when it comes to water supply.
The blizzard that dumped snow along the Front Range in March
helped Colorado nearly reach its average snowpack for the
winter, federal data shows. But last year’s historically dry
weather means that streams are likely to run lower than normal,
potentially restricting the amount of water some consumers can
use, experts said… Areas east of the Continental Divide
had above average snowpack, but the Colorado River Basin on the
west was below average….
A federal judge has thrown out a legal action from multiple
environmental organizations seeking to halt the expansion of a
key Denver Water storage facility, citing no legal authority to
address the challenge. … The expansion of Gross Reservoir in
Boulder County is intended to provide additional water storage
and safeguard against future shortfalls during droughts. The
utility currently serves customers in Denver, Jefferson,
Arapahoe, Douglas and Adams counties. In July 2020, the Federal
Energy Regulatory Commission gave its approval for
the design and construction of the reservoir’s expansion. The
project would add 77,000 acre-feet of water storage and 131
feet to the dam’s height for the utility’s “North System” of
water delivery.
State officials are putting farmers in south-central Arizona on
notice that the continuing drought means a “substantial cut” in
deliveries of Colorado River water is expected next year. A
joint statement issued Friday by the state Department of Water
Resources and the Central Arizona Project said an expected
shortage declaration “will result in a substantial cut to
Arizona’s share of the river, with reductions falling largely
to central Arizona agricultural users.” The Central Arizona
Project is an aqueduct system that delivers Colorado River
water to users in central Arizona and southern Arizona,
including farmers, cities and tribes.
When it comes to water in the West, a lot of it is visible.
Snow stacks up high in the mountains then eventually melts and
flows down into valleys. It’s easy to see how heavy rains and
rushing rivers translate into an abundance of available water.
But another important factor of water availability is much
harder to see. Beneath the surface, the amount of moisture
held in the ground can play a big role in how much water makes
it down to rivers and reservoirs – and eventually into the
pipes that feed homes and businesses. Elise Osenga is a
community science manager for the Aspen Global Change Institute
– a nonprofit focused on expanding scientific understanding of
climate change.
Local water providers say the current drought is one of the
worst in Colorado history. Mesa County ranges from extreme
drought to exceptional drought in areas and it doesn’t appear
to be improving anytime soon. Below average spring runoff is
anticipated by local water providers as watersheds are working
to be replenished after last year’s drought. … The wildfires
in the Colorado River basin last summer have scarred
significant portions of the Colorado River which may result in
debris, ash, and dense mud flowing into the Colorado River
watershed, which will impact water quality for many water
entities in Mesa County.
The Fort Yuma-Quechan Indian Tribe is situated at a nexus in
the Colorado River Basin. That’s true in a geographic sense.
The tribe’s reservation overlays the Arizona-California border
near Yuma, Arizona. The two states are heavily reliant on water
from the Colorado River. The reservation also abuts the
U.S.-Mexico border where the river flows into Mexico for use in
cities and on farms. One of the river’s largest irrigation
projects, the All-American Canal, was dug through the tribe’s
land, and flows from the reservation’s northeastern boundary to
its far southwestern corner, on its way to irrigate crops in
California’s Imperial Valley. The confluence of the Colorado
River and one of its historically important tributaries, the
Gila River, is nearby.
About 40 million Americans in the West and Southwest rely on
the Colorado River for drinking water, as do the region’s
massive agriculture and recreation industries. Water has been
the most valuable commodity in the West since the time of the
pioneers. It became a source of modern political power when the
water of the Colorado River was divvied up among seven Western
States in the 1920s — the Jack Nicholson movie “Chinatown”
dramatized California’s legendary water battles. Today, a
rapidly shrinking Colorado River is forced to support
relentless development in California and across the West — very
thirsty development.
Despite the recent history-making blizzard on Colorado’s Front
Range, statewide snowpack sits at 92 percent of average as of
March 19, down from 105 percent of average at the end of
February, according to the Natural Resources Conservation
Service. Just two river basins, the Arkansas and the Rio
Grande, are registering above average at 101 percent and 106
percent respectively. Among the driest are the Gunnison Basin,
at 86 percent of average, and the San Juan/Dolores, at 83
percent, both in the southwestern part of the state.
Many of the wetlands in the western United States have
disappeared since the 1700s. California has lost an astonishing
90 percent of its wetlands, which includes streamsides, wet
meadows and ponds. In Nevada, Idaho and Colorado, more than 50
percent of wetlands have vanished. Precious wet habitats now
make up just 2 percent of the arid West — and those remaining
wet places are struggling. Nearly half of U.S. streams are in
poor condition, unable to fully sustain wildlife and people,
says Jeremy Maestas, a sagebrush ecosystem specialist with the
NRCS who organized that workshop on Wilde’s ranch in 2016. As
communities in the American West face increasing water
shortages, more frequent and larger wildfires and unpredictable
floods, restoring ailing waterways is becoming a necessity.
Water scarcity is often understood as a problem for regions
experiencing drought, but a new study from Cornell and Tufts
universities finds that not only can localized water shortages
impact the global economy, but changes in global demand send
positive and negative ripple effects to water basins across the
globe. … [I]n the lower Colorado River basin, the worst
economic outcomes arise from limited groundwater availability
and high population growth, but that high population growth can
also prove beneficial under some climatic scenarios.
Arizona tribal officials told a Senate committee Wednesday that
the federal government can help address a crisis with water
infrastructure on their lands through more funding, and less
meddling. Navajo Department of Water Resources Director Jason
John and Colorado River Indian Tribes Chairwoman Amelia Flores
made the comments during a Senate Indian Affairs Committee
hearing on water infrastructure for Native communities. Leaders
of Oregon and Alaska tribes also testified at the
hearing.
Meager anticipated snowmelt runoff is expected to mean another
challenging year for maintaining even below-optimal levels of
flows in the Colorado River downstream of the Palisade area for
the benefit of endangered fish. … What’s referred to as
the 15-Mile Reach of the river between the Palisade area and
the Gunnison River confluence is of particular concern for the
Upper Colorado River Endangered Fish Recovery Program, which
focuses on four endangered fish. The stretch is primarily used
by two of the fish — the razorback sucker and Colorado
pikeminnow. But it’s also used by a third, the bonytail. And a
fourth, the humpback chub, which favors downstream stretches
such as Westwater Canyon, indirectly benefits from efforts to
bolster flows in the 15-Mile Reach.
One of the most critical negotiations for Utah’s future is
coming at a time when Utah’s delegations in Washington D.C. may
be less influential than every other party at the table. The
Colorado River Compact, hammered out in 1922 with few
amendments over the years, expires in 2026. Every other state
in the compact other than Utah has a majority Democratic or
split delegation in Washington. Those states? Colorado, New
Mexico, Arizona, Nevada and California.
A showdown is looming on the Colorado River. The river’s
existing management guidelines are set to expire in 2026. The
states that draw water from it are about to undertake a new
round of negotiations over the river’s future, while it’s
facing worsening dry conditions due in part to rising
temperatures. That means everyone with an interest in the
river’s future — tribes, environmentalists, developers,
business groups, recreation advocates — is hoping a new round
of talks will bring certainty to existing water supplies and
demands.
Much of the U.S. West is facing the driest spring in seven
years, setting up a climate disaster that could strangle
agriculture, fuel deadly wildfires and even hurt power
production. Across 11 western states, drought has captured
about 75% of the land, and covers more than 44% of the
contiguous U.S., the U.S. Drought Monitor said. While
drought isn’t new to the West, where millions of people live,
grow crops and raise livestock in desert conditions that
require massive amounts of water, global warming is
exacerbating the problem — shrinking snowpack in the Rocky
Mountains and extending the fire season on the West Coast.
The Bureau of Reclamation is awarding $42.4 million in grants
to 55 projects throughout 13 states. These projects will
improve the water reliability for these communities by using
water more efficiently and power efficiency improvements that
water supply reliability and generate more hydropower…. In
California, near the Arizona border, the Bard Water District
will receive $1.1 million to complete a canal lining and piping
project. The project is expected to result in annual water
savings of 701 acre-feet, which will remain in the Colorado
River system for other uses.
The Division of Boating and Waterways (DBW) will be accepting
grant applications for quagga and zebra mussel infestation
prevention programs from March 22 through April 30,
2021. All applications must be received by 5 p.m. on
Friday, April 30, 2021. … California water body
authorities have recognized the westward spread of mussel
infestation via the Colorado River System and the potential
harm to state waterways should lakes and reservoirs become
invaded. To help prevent California waterways from infestation,
DBW provides grants to entities that own or manage any aspect
of water in a reservoir that is open for public recreation and
is mussel-free.
After a record dry summer and fall — and with winter snowpack
currently at 70% of normal levels — Utah Gov. Spencer Cox
signed an emergency order Wednesday declaring a state of
emergency due to drought conditions. The move comes after a
recommendation from the state’s Drought Review and Reporting
Committee and opens the door for drought-affected communities
and agricultural producers to potentially access state or
federal emergency funds and resources, according to a news
release. Cox said Wednesday that state leaders have been
“monitoring drought conditions carefully and had hoped to see
significant improvement from winter storms.”
Western water managers are contending with the growing threat
of shortages. Flow has dwindled on major water systems like the
Rio Grande and the Colorado River, which each supply water to
millions of people. With temperatures steadily rising, cloud
seeding poses one attractive solution.
Grain by grain, sandbars are ecologically important to the
Colorado River system for humans and wildlife, say scientists.
How sand, silt and clay move along and become deposited within
the river corridor in the Grand Canyon National Park,
downstream from Glen Canyon Dam, has become an important
question to a number of government agencies as well as to
Native American tribes. The answer impacts the entire Colorado
River ecosystem and will help scientists better understand how
the Colorado River system works.
As Colorado digs out from the recent blizzard, each heavy
shovel full of snow proves the storm brought plenty of
moisture. But is it enough to free the state from its drought
conditions? Russ Schumacher, the Colorado state
climatologist, said the answer largely depends on location. …
Colorado’s drought conditions had improved ahead of the storm.
After record dry weather over the summer and fall, snowpack
levels had inched toward normal throughout the winter, but
western Colorado continued to miss out on the snowfall.
The water flow in the Grand Canyon is temporarily changing and
it could reveal some surprises, geologists said. The U.S.
Geological Survey said Sunday that an 11-day “spring
disturbance” flow will start Monday and will drop water levels
in parts of the Grand Canyon. … While dam maintenance
may not seem exciting, the drop in water could reveal parts of
the Colorado riverbed that hasn’t been seen in decades, USGS
said. It could also impact in the Colorado River
ecosystem. The change in water levels will also
mimic what the Colorado River was like before the dam was
built, USGS said.
I’ve been writing a lot about the broken sewage system in
Tijuana causing spills into San Diego. Part of the concern, San
Diego officials told me, is that Mexico lacks a system to
monitor whether businesses are dumping toxic waste into the
sewer system. That’s part of the reason why it’s risky to reuse
any of that river water because, if we don’t know what’s in the
water, we can’t be sure how to best treat it. San Diego is
about to run into this issue in a big way with its Pure Water
project, a multibillion-dollar system that’s going to recycle
the city’s sewage and treat it so, well, you can drink
it.
Scientists and boatmen with the United States Geological Survey
are preparing for a busy week on the Colorado River as
engineers at Glen Canyon Dam prepare to reduce the water
flowing out of Lake Powell substantially. In order to conduct
maintenance on the concrete apron downstream of the dam,
engineers will be limiting the water that runs through the
dam’s turbines starting Monday and continuing through the rest
of the week.
Sometime in the middle of next year, if Northern Water gets its
way, the bulldozers will start piling earth and rock 25 stories
high to plug this dry basin southwest of Loveland
forever. Four miles to the south, they’ll build another
dam to keep their newly-made bathtub from leaking out the back
toward Lyons. Drill crews will bore a massive pipeline through
the hogback making up the east edge of the bathtub, in order to
feed Carter Lake a few hundred yards to the east. They’ll move
a power line. Help build a surrounding open space park. Upgrade
a sewage plant in Fraser. Four years later, they’ll close dam
gates reinforced to hold back 29 billion gallons of life-giving
water.
Mark your calendars now for our virtual Lower Colorado
River Tour on May 20 to learn about the important role the
river’s water plays in the three Lower Basin states of Nevada,
Arizona and California, and how it helps to sustain their
cities, wildlife areas and farms. Registration is coming

the Colorado River from Hoover Dam and its reservoir Lake
Mead, the nation’s tallest concrete dam and largest reservoir
respectively, down to the U.S./Mexico border and up to the
Salton Sea.
The Grand Canyon Protection Act was recently introduced by U.S.
Rep. Raύl Grijalva and passed in the House and has been
introduced in the Senate by Sen. Kyrsten Sinema. The bills will
permanently protect about 1 million acres of public lands
surrounding Grand Canyon from the harmful and lasting damage of
new uranium mining. … This legislation is critical
to stopping the threats that mining poses to water quality and
quantity, unique habitats and wildlife pathways, and to sacred
places. -Written by Sandy Bahr, director for Sierra
Club’s Grand Canyon Chapter, and Amber Wilson
Reimondo, Energy Program director with Grand Canyon
Trust.
As persistent drought and climate change threaten the Colorado
River, several states that rely on the water acknowledge they
likely won’t get what they were promised a century ago. But not
Utah. Republican lawmakers approved an entity that could push
for more of Utah’s share of water as seven Western states
prepare to negotiate how to sustain a river serving 40 million
people. Critics say the legislation, which the governor still
must sign, could strengthen Utah’s effort to complete a
billion-dollar pipeline from a dwindling reservoir that’s a key
indicator of the river’s health.
A recent report from Colorado River experts says it’s time for
radical new management strategies to safeguard the Southwest’s
water supplies. It’s meant to inform discussions on how to
renegotiate certain parts of the Law of the River that will
expire in 2026. KNAU’s Melissa Sevigny spoke about the report
with Jack Schmidt, director of the Center for Colorado River
Studies at Utah State University.
A bipartisan group of California lawmakers is confronting
pollution problems along the U.S.-Mexico border, especially in
the Tijuana River Valley between San Diego and Tijuana. Several
House members who represent Southern California introduced a
bill called the Border Water Quality Restoration Act. Similar
legislation was presented last week in the U.S. Senate. If
approved, it will give the Environmental Protection Agency the
authority to coordinate all federal, state, and local agencies
when planning construction and infrastructure projects to
mitigate pollution in waterways throughout the southern border.
For the first time ever, rancher Jimmie Hughes saw all 15 of
the ponds he keeps for his cattle dry up at the same time this
year. Now, he and his co-workers are forced to haul tanks
of water two hours over dusty, mountain roads to water their
300 cows. … The Southwest is locked in drought again,
prompting cutbacks to farms and ranches and putting renewed
pressure on urban supplies. Extreme to exceptional drought is
afflicting between 57% and 90% of the land in Colorado, New
Mexico, Nevada, Utah and Arizona and is shriveling a snowpack
that supplies water to 40 million people from Denver to Los
Angeles, according to the U.S. Drought Monitor.
A coalition of San Diego County elected representatives
introduced a bill on Monday to address water pollution along
the U.S.-Mexico border. The Border Water Quality Restoration
and Protection Act would designate the Environmental Protection
Agency as the lead agency coordinating federal, state and local
agencies’ efforts to build and maintain infrastructure projects
aimed at reducing pollution along the border.
A new Colorado River study predicts we may need to make even
deeper cuts to keep our reservoirs from tanking over the long
haul. But the dire conclusions within the study aren’t what
make it so intriguing. It’s how the group arrived at them. The
Future of the Colorado River project, an effort based out of
Utah State University, has produced six white papers to
evaluate new approaches to water management along the river.
And, most notably, it is using the Colorado River Simulation
System (CRSS), the same modeling tool the Bureau of Reclamation
uses to develop its long-term water availability forecasts for
the basin. - Written by Joanna Allhands, a columnist for the Arizona
Republic.
When [the Colorado River Compact was] signed in 1922,
the Colorado River drainage was divided into two divisions;
Upper: Colorado, Wyoming, New Mexico, Utah; Lower: Arizona,
California, Nevada. At that time, it was felt the total average
annual flow was 16.4 million acre feet. As a result, each basin
was assigned 50%, or 7.5 million acre feet, with the 1.4
million acre feet surplus allocated to Mexico. … As a
result, the Upper Basin is obligated to provide 7.5M acre feet
to the Lower Basin, regardless of the actual flow of water in
any given year. Obviously, snowpack and the consequent flow is
not a constant and years of drought and low flows create a
problem for the Upper Basin. -Written by Bryan Whiting, a columnist for the
Glenwood Springs (Colo.) Post Independent.
The hot dry conditions that melted strong snowpack early in
2020 and led to severe drought, low river flows and record
setting wildfires across the state could be a harbinger of what
is to come in Colorado. Climate change is likely to drive
“chaotic weather” and greater extremes with hotter droughts and
bigger snowstorms that will be harder to predict, said Kenneth
Williams, environmental remediation and water resources program
lead at Lawrence Berkeley National Laboratory, headquartered in
California.
Much of the western U.S. continues to endure a long-term
drought, one that threatens the region’s water supplies
and agriculture and could worsen wildfires this year. In fact,
some scientists are calling the dryness in the West a
“megadrought,” defined as an intense drought that lasts
for decades or longer. Overall, about 90% of the West is
now either abnormally dry or in a drought, which is among the
highest percentages in the past 20 years, according to this
week’s U.S. Drought Monitor.
A bill aimed at addressing pollution along the U.S.- Mexico
border and improving water quality in the Tijuana and New
rivers was introduced Wednesday. The Border Water Quality
Restoration and Protection Act would designate the
Environmental Protection Agency as the lead agency coordinating
federal, state and local agencies to build and maintain
infrastructure projects aimed at reducing pollution along the
border. It would also require the EPA and other agencies to
identify a list of priority projects and would authorize the
EPA to accept and distribute federal, state, and local funds to
build, operate and maintain those projects.
Anyone who has hosted a good dinner party knows that the guest
list, table setting and topic of conversation play a big role
in determining whether the night is a hit or the guests leave
angry and unsatisfied. That concept is about to get a true test
on the Colorado River, where chairs are being pulled up to a
negotiating table to start a new round of talks that could
define how the river system adapts to a changing climate for
the next generation.
In 1854, the Gadsden Purchase modified a short, 30-mile stretch
of the western border to be the midline of the Colorado River.
The Mexican and U.S. governments soon realized that when these
rivers shifted across their floodplains, questions about
national jurisdiction arose. For example, an exasperated U.S.
agent reported that “the lower Colorado … alters its channel
from time to time, cutting off a large stretch of land on one
bank and depositing the soil on the other or leaving its old
bed and tearing through a large piece of silty bottom land to
form a channel some distance away.” The agent went on to
complain that these movements made it difficult to determine
which land fell on which side of the line…
On Feb. 22, 2021, Lake Powell was 127.24 feet below ‘Full Pool’
or, by content, about 38% full. Based on water level
elevations, these measurements do not account for years of
sediment (clay, silt, and sand) accumulation—the millions of
metric tons on the bottom. Geologist James L. Powell said, “The
Colorado delivers enough sediment to Lake Powell to fill 1,400
ship cargo containers each day.” In other words, Lake
Powell is shrinking toward the middle from top and bottom. The
lake is down over 30 feet from one year ago, and estimates
suggest it could drop another 50 feet by 2026. The Bureau of
Reclamation estimated the lifespan of Glen Canyon Dam at
500–700 years. Other estimates aren’t as optimistic, including
some as low as 50 years.
A Senate committee unanimously approved a bill Thursday to
create Utah’s Colorado River Authority, which would be tasked
with helping the state renegotiate its share of the river.
Originally the bill allowed broad reasons to close meetings and
protect records. It’s since been changed twice to come more
into compliance with the state’s open meeting and record laws.
Critics of the bill said it’s still not enough. Mike O’Brien,
an attorney with the Utah Media Coalition, said having a
narrower scope for open meetings and records exemptions makes
the bill better than when it was first introduced. But he
wishes it would follow laws already there.
Like a giant garbage disposal, three huge new green pipes sit
on Mexico’s side of the border, shredding trash in the Tijuana
River that would otherwise jam this critical piece of the
city’s wastewater system that caused spills on the United
States side.
Federal regulators have issued a preliminary permit for a
pumped-hydropower project using water from Lake Powell, but
conservation groups say climate change could make the plan
unsustainable. The project would pump water from the lake,
drain it downhill to a generator, and send the power to massive
batteries for storage. The 2,200-megawatt project would supply
cities in Arizona, California and Nevada, over lines previously
used by the retired Navajo Generating Station. Gary Wockner,
executive director for Save the Colorado, which opposes the
plan, said falling water levels will make the Colorado River
Basin an unreliable source of water.
Arizona, California, and Nevada will need to cut their use of
Colorado River water by nearly 40 percent by 2050. A
study by researchers at Utah State University, which
the Arizona Daily Star reported this past Sunday, noted
that Colorado, New Mexico, Utah, and Wyoming—the Upper Basin
states—will have to reduce their usage, as well, though not by
as much as those pulling water from the Lower Basin.
From California’s perspective, the view upriver is not
encouraging. More than half of the upper part of the river
basin is in “exceptional drought,” according to the U.S.
Drought Monitor, while the Lower Basin is even worse off: More
than 60% of it is in the highest drought level. In January,
water levels in Lake Powell, the river’s second-largest
reservoir, dropped to unprecedented depths, triggering a
drought contingency plan for the first time for the Upper Basin
states of Colorado, Wyoming, Utah and New Mexico. Since
2000, the Colorado River Basin has seen a sustained period of
less water and hotter days. This is, as climate scientists like
to say, the “new normal.”
“Basic climate science reveals that Lake Powell is not a
reliable water source for this ill-conceived project.” The
reference to ‘basic climate science’ refers to recent computer
models that show a drier climate throughout the American
Southwest over the next few decades, allegedly due to the
continued use of fossil fuels all around the globe. But even
without access to clever computer models, we have all seen Lake
Powell and Lake Mead — America’s two largest water reservoirs —
struggle to remain even half full, as we watch water users
extract more water than nature can replace.
Utah House Bill 297 is a dangerous spending bill that provides
its benefactors with exemptions to conflict-of-interest laws
that raises serious moral questions about what is happening at
the Utah Legislature. The bill creates another heavily-funded
and secretive government agency — the Colorado River Authority
— that would receive an initial $9 million, plus $600,000 per
year thereafter, in addition to collecting unknown sums of
money from other agencies. -Written by Claire Geddes, a consumer advocate and former
director of Utah Legislative Watch.
Less water for the Central Arizona Project — but not zero
water. Even more competition between farms and cities for
dwindling Colorado River supplies than there is now. More
urgency to cut water use rather than wait for seven river basin
states to approve new guidelines in 2025 for operating the
river’s reservoirs. That’s where Arizona and the Southwest are
heading with water, say experts and environmental advocates
following publication of a dire new academic study on the
Colorado River’s future. The study warned that the river’s
Upper and Lower basin states must sustain severe cuts in river
water use to keep its reservoir system from collapsing due to
lack of water. That’s due to continued warming weather and
other symptoms of human-caused climate change, the study said.
Big projects aimed at stemming the toxic sewage flowing from
Tijuana into Imperial Beach and the surrounding region are on
the horizon and that’s a welcome development. But any such
improvements come with a nagging question based on historical
experience: How long will this fix last? Cross-border pollution
has been a problem for the better part of a century and has
defied past efforts to solve it. It’s not that previous actions
didn’t help. Some did, and they greatly diminished the health
and environmental threat — and reduced beach
closures. -Written by Michael Smolens, a columnist for the San Diego
Union-Tribune.
Utah lawmakers say drought and the dwindling Colorado River
make it more important than ever for the state to act now to
safeguard its interest in the river.
In the five years since Colorado’s Water Plan took effect, the
state has awarded nearly $500 million in loans and grants for
water projects, cities have enacted strict drought plans,
communities have written nearly two dozen locally based stream
restoration plans, and crews have been hard at work improving
irrigation systems and upgrading wastewater treatment plants.
But big challenges lie ahead — drought, population growth,
accelerating climate change, budget cuts, wildfires and
competing demands for water, among others.
The Colorado River supports over 40 million people spread
across seven southwestern states, 29 tribal nations, and
Mexico. It’s responsible for the irrigation of roughly 5.5
million acres of land marked for agricultural use. Local and
regional headlines show the river is in crisis. The nation
mostly isn’t listening.
A proposed water recycling project in Southern California could
result in Nevada getting some of the Golden State’s share of
water from the Colorado River. The Southern Nevada Water
Authority could invest up to $750 million into the water
treatment project. In return for the investment, it could get a
share of California’s water in Lake Mead. If built, the project
would give the region another tool to protect itself against
the ongoing strain of drought conditions on the Colorado River.
[T]he president of New York-based hedge fund Water Asset
Management … has called water in the United States “a
trillion-dollar market opportunity.” The hedge fund invested
$300 million in farmland in Colorado, California, Arizona and
Nevada as of 2020, including $16.6 million on 2,220 acres of
farmland with senior water rights in Colorado’s Grand Valley
just upstream from where the Colorado River crosses into Utah.
In the gloomiest long-term forecast yet for the
drought-stricken Colorado River, a new study warns that lower
river basin states including Arizona may have to slash their
take from the river up to 40% by the 2050s to keep reservoirs
from falling too low. Such a cut would amount to about twice as
much as the three Lower Basin states — Arizona, California and
Nevada — agreed to absorb under the drought contingency plan
they approved in early 2019. Overall, the study warned that
managing the river sustainably will require substantially
larger cuts in use by Lower Basin states than currently
envisioned, along with curbs on future diversions by Upper
Basin states.
I’ve written in the past about the San Diego County Water
Authority’s efforts to divest from its parent agency the
Metropolitan Water District of Southern California. That
includes the bad blood between the two agencies stemming from
MWD’s water cutbacks to San Diego in 1991, and how local
leaders felt they were mistreated. What I didn’t realize was
just how far back the tension goes between San Diego leaders
and MWD. All the way back to the Great Depression…
Much has been said about a “new normal” in the Colorado River
Basin. The phrase describes reduced flows in the 21st century
as compared to those during much of the 20th century. Authors
of a new study contemplate something beyond, what they call a
“new abnormal.” The future, they say, might be far dryer than
water managers have been planning for. … In the 133-page
report, they identified a wide variety of alternative
management ideas, not simple tweaks but “significant
modifications or entirely new approaches.”
Utah legislative leaders on Thursday unveiled plans for a new
$9 million state agency to advance Utah’s claims to the
Colorado River in hopes of wrangling more of the river’s
diminishing flows, potentially at the expense of six
neighboring states that also tap the river. Without any prior
public involvement or notice, lawmakers assembled legislation
to create a six-member entity called the Colorado River
Authority of Utah, charged with implementing “a management plan
to ensure that Utah can protect and develop the Colorado River
system.”
It would be arguably the most ambitious public works project in
San Diego history. The envisioned pipeline would carry Colorado
River water more than 130 miles from the Imperial Valley —
through the Anza-Borrego Desert State Park, tunneling under the
Cuyamaca Mountains, and passing through the Cleveland National
Forest — to eventually connect with a water-treatment plant in
San Marcos. An alternative route would run through the desert
to the south, boring under Mt. Laguna before emptying into the
San Vicente Reservoir in Lakeside. Estimated cost: roughly $5
billion. New water delivered: None.
Migratory birds have followed the same flight patterns for
millennia, searching for abundant food resources. The journey
is often risky, and birds undergo harsh weather patterns—from
storms that can throw them off course to dry arid landscapes
that provide little to no food resources. A new study published
this week in Ornithological Applications found tens of millions
of birds depend on the river and wetland habitats weaved within
the Colorado River Delta and California’s Central Valley while
they make their journey across the dry western landscapes,
reports Corryn Wetzel for Audubon.
Comedian Ron White once joked that we should have two
levels of national security warnings: Find a helmet and put on
a helmet. If such a system were in place
for controversies, Arizona’s water community would
now be in the “put on a helmet” stage. Tensions were
already high over a proposal to transfer Colorado River
water from a farm in La Paz County to Queen
Creek. And now that the recommendation
has quietly changed, some folks in on-river
communities view it as nothing less than the start
of World War III. Heaven help us if it is. -Written by Joanna Allhands, a columnist for the Arizona
Republic
Dry conditions are the worst they’ve been in almost 20 years
across the Colorado River watershed, which acts as the drinking
and irrigation water supply for 40 million people in the
American Southwest. As the latest round of federal
forecasts for the river’s flow shows, it’s plausible, maybe
even likely, that the situation could get much worse this year.
Understanding and explaining the depth of the dryness is up to
climate scientists throughout the basin. We called several of
them and asked for discrete numbers that capture the current
state of the Colorado River basin.
Mayors and county supervisors in towns along the Colorado River
were already upset five months ago when the state water
agency endorsed an investment company’s plan to take water
from farmland near the river and sell it to a growing Phoenix
suburb. Now, they’re incensed that the agency, which initially
suggested holding back a large portion of the
water, changed its stance and will let the company
sell most of the water to the town of Queen Creek. Elected
leaders in communities along the river say they intend to
continue trying to stop the proposed deal, which would need to
be approved by the federal Bureau of Reclamation.
Water suppliers along the drought-stricken Colorado River hope
to tackle another tricky issue after the U.S. Bureau of
Reclamation installs a new leader: salty water. The river
provides water for 40 million people from Colorado to
California, and helps irrigate 5.5 million acres of farm and
ranchland in the U.S. But all that water also comes with 9
million tons of salt that flow through the system as it heads
to Mexico, both due to natural occurrence and runoff, mostly
from agriculture. Salt can hurt crop production, corrode
drinking water pipes, and cause other damage.
Jeff Lukas calls the Colorado the “charismatic megafauna of
Western rivers.” This riverine equivalent of grizzly bears,
bald eagles, and humpback whales gets lots of attention,
including national attention. Some of that attention is
deserved. It has the nation’s two largest reservoirs, among the
nation’s tallest dams, and many of the most jaw-dropping
canyons and eye-riveting national parks in the country. It also
has 40 million to 50 million people in Colorado and six other
southwestern states, plus Mexico, who depend upon its water,
and a history of tensions that have at times verged on the
political equivalent of fist-fights.
We are now past the halfway mark in California’s normally
wettest winter months, and the wet season to date has been
anything but. Most of the state has received less than half of
its average annual precipitation to date. Coming after a very
dry Water Year 2020 these conditions are concerning. More
precipitation will certainly occur in February and March, but
will it be enough to erase the state’s large
deficit?
U.S. Reps. Raul Ruiz, D-Palm Desert, and Juan Vargas,
D-San Diego reintroduced a bill this week that is aimed at
cleaning up the New River, a highly polluted waterway
originating near Mexicali, Mexico that flows
north, emptying into the Salton Sea. The bill, HR491,
would direct the U.S. Environmental Protection Agency to create
an organization to be called the California New River
Restoration Program, which would coordinate funding and cleanup
projects.
The Colorado River is the lifeblood of the American West, but
the viability of the massive river basin is being threatened by
climate change. To plan future water use in the region — which
includes Arizona — the Central Arizona Project is teaming up
with NASA and Arizona State University, to evaluate how climate
and land-use changes will affect patterns of hydrology. Using
state-of-the-art satellite imaging, scientists will measure and
evaluate how water flows throughout the basin.
The building of dams on the Colorado River has forever changed
the ebb and flow, flooding, drying and renewal cycle of what
was once Lake Cahuilla, changing its character and changing its
name to the Salton Sea. Entrepreneurs once thought that the
Salton Sea would become a sportsman’s mecca, providing fishing,
boating, and waterskiing experiences like no other. There were
a few decades where that dream seemed to be true. Then it
wasn’t.
The quality of the water crossing into San Diego from Tijuana
during storms is, well, not the greatest. If it could be
successfully recycled one day, that same polluted source would
be valuable to a region like ours that’s prone to drought.But
who owns the Tijuana River and who needs its water the most are
complex questions, because the area is ruled by international
treaties.
Twenty years ago, the Colorado River’s hydrology began tumbling
into a historically bad stretch. … So key players across
seven states, including California, came together in 2005 to
attack the problem. The result was a set of Interim Guidelines
adopted in 2007… Stressing flexibility instead of rigidity,
the guidelines stabilized water deliveries in a
drought-stressed system and prevented a dreaded shortage
declaration by the federal government that would have forced
water supply cuts.
The lower Colorado River Basin, which is primarily in Arizona,
is projected to have as much as sixteen percent less
groundwater infiltration by midcentury compared to the
historical record. That’s because warming temperatures will
increase evaporation while rain- and snowfall are expected to
remain the same or decrease slightly.
The U.S. Geological Survey is in the beginning stages of
learning more about this river via an expanded and more
sophisticated monitoring system that aims to study details
about the snowpack that feeds the river basin, droughts and
flooding, and how streamflow supports groundwater, or vice
versa.
Mexico is obligated under a 1944 treaty to deliver to the
United States a set amount of water from the Rio Grande and its
tributaries over a five-year period. … The last-minute
agreement signed Oct. 21 settles the conflict. Mexico will
transfer ownership of water stored in two border reservoirs to
the United States to make up the deficit.
What’s in the Tijuana River? Ammonia, a byproduct of raw
sewage. Phosphorous, an ingredient in soaps and cleaners that’s
banned in the U.S. Metals used in the industrial plating
industry. Parasitic worms. And DEHP, a chemical added to
plastics. And of course, there’s poo.
For weeks, a water dispute between the Mexican government and
Mexican farmers and between the United States and Mexico was
brewing and escalating. October 24 was the deadline by which
Mexico was supposed to have provided the United States with all
of the water from the Rio Grande it owes the United States
every five years. But this year’s expected water delivery set
off months-long protests…
Imperial County Supervisor Ryan Kelley wants the board to work
with Congressman Juan Vargas, D-Chula Vista, and the county’s
lobbyists in Washington, D.C., to draft a legislation to fully
fund a wastewater treatment project to clean the New River.
A team of scientists at Utah State University has developed a
new tool to forecast drought and water flow in the Colorado
River several years in advance. Although the river’s headwaters
are in landlocked Wyoming and Colorado, water levels are linked
to sea surface temperatures in parts of the Pacific and
Atlantic oceans and the water’s long-term ocean memory.
Despite that reduction in flow, total storage behind Glen
Canyon and Hoover dams has dropped only 2.6 million acre feet.
That is far less than you’d expect from 12 years of 1.2 maf per
year flow reductions alone. That kind of a flow reduction
should have been enough to nearly empty the reservoirs. Why
hasn’t that happened? Because we also have been using less
water.
The bill, which was written by state Sen. Ben Hueso, also aims
to address some of the binational challenges in managing the
watershed. The plan that the California EPA is putting together
will create a framework for how California can work with the
Mexican and U.S. governments.
Tensions between Mexico and the United States over water
intensified this month as hundreds of Mexican farmers seized
control of La Boquilla dam in protest over mandatory water
releases. The protesters came from parched Chihuahua state,
nearly 100 square miles of land pressed against the U.S.
border, where farmers are opposing the delivery of over 100
billion gallons of water to the United States by October 24.
The mayor of Imperial Beach and governor of Baja California are
in a public spat over cross-border sewage spills. Gov. Jaime
Bonilla has held three separate press conferences this month
demanding Mayor Serge Dedina apologize for his public
criticisms of Mexico’s inability to stop sewage from flowing
into the United States.
Mexican farmers in the drought-stricken state of Chihuahua are
pitted against riot squads from the national guard in an
increasingly violent standoff over their government’s decision
to ship scarce water supplies to the United States…Under the
treaty, Mexico sends water from rivers in the Rio Grande basin
to the United States, which in turn sends Mexico water
in the Colorado River further to the west.
At the September meeting of Metropolitan’s Water Planning and
Stewardship Committee, Laura Lamdin, an associate engineer in
water resource management, gave a presentation on how the
United States and Mexico built a collaborative relationship,
the many accomplishments that have come as a result, and a look
at the work currently in progress.
In Utah, there is a significant effort underway to build a
water delivery pipeline from Lake Powell to transport part of
Utah’s Colorado River entitlement to Utah’s St. George area. As
the federal environmental review for the proposed Lake Powell
Pipeline in Utah continues, Utah’s six fellow Colorado River
Basin states weighed in as a group, cautioning that unresolved
issues remain.
Protesters gathered on Sunday in drought-hit northern Mexico in
an attempt to retain control of a dam key to government efforts
to diffuse tensions over a water-sharing pact with the United
States. Mexican President Andres Manuel Lopez Obrador, who has
been working to maintain a good relationship with U.S.
President Donald Trump, said on Friday that Mexico must comply
with its obligations.
For 75 years, through tensions and disputes over immigration,
narcotrafficking and trade, Mexico and the United States have
sent each other billions of gallons of water annually to
irrigate farms along the border under a treaty signed during
World War II. But today, the 1944 agreement is facing
increasingly violent opposition in drought-parched Chihuahua
state, where protesters have seized control of a major dam to
dramatize the plight of farmers…
Dizzying in its scope, detail and complexity, the scientific
information on the Basin’s climate and hydrology has been
largely scattered in hundreds of studies and reports. Some
studies may conflict with others, or at least appear to. That’s
problematic for a river that’s a lifeline for 40 million people
and more than 4 million acres of irrigated farmland.
Mexico’s water wars have turned deadly. A long-simmering
dispute about shared water rights between Mexico and the United
States has erupted into open clashes pitting Mexican National
Guard troops against farmers, ranchers and others who seized a
dam in northern Chihuahua state.
The cuts are a plan to keep Lake Mead, a reservoir at the
Arizona-Nevada boundary, functional. Water levels have
precipitously dropped as a result of historic overallocation
and a drought that started in 2000. … ASU Now checked in with
Sarah Porter of the Kyl Center for Water Policy at the Morrison
Institute on how these new developments will impact the Copper
State and its residents.
The Mexican National Guard said Wednesday that two people had
died in a gunfight with military police near a protest at a dam
that diverts water away from an area hit by drought to the
United States. … The protest comes amid plans to divert more
to the United States due to a “water debt” Mexico has accrued
under a 1944 water-sharing treaty between the countries.
EPA Administrator Andrew Wheeler said Wednesday the agency
would pay for more water treatment south of the border, and
work with San Diego to control trash coming into the United
States from Mexico by way of the Tijuana River. Wheeler made
the announcement during a visit to Southern California, a
region long plagued by sewage, water, trash, and other
contaminants flowing from Mexico.
The two projects — which will cost $25 million and are funded
by the EPA’s Border Water Infrastructure Program — will control
sewage and wastewater, sediment and trash that flows from the
Tijuana River across the U.S.-Mexico border into San Diego, EPA
Administrator Andrew Wheeler said during a press conference
Wednesday at the U.S. Coast Guard station in San Diego.
U.S. Customs and Border Protection has announced plans to
extend the border wall and have it cut across the Tijuana River
where the river enters the U.S. in San Diego. … Usually, the
river has more debris and old tires in it than it has water.
But there is no barrier between the two countries here.
Above-average temperatures in spring resulted in a paltry 57%
runoff, nowhere near enough water to refill the reservoirs that
remain half-empty. Based on these conditions, the U.S. Bureau
of Reclamation recently determined that 2021 will be a “tier
zero” year under the Lower Colorado River Basin Drought
Contingency Plan, with reduced water deliveries for Arizona,
Nevada, and Mexico.
A friend last week pointed out something remarkable. Arizona,
California, and Nevada are forecast this year to use just 6.8
million acre feet of their 7.5 million acre foot allocation of
water from the main stem of the Colorado River. And that’s not
just a one-off.
The latest forecast from the U.S. Bureau of Reclamation,
released last week, predicts that by the end of 2020, Lake
Mead, which furnishes Central Arizona Project water, will be at
1,085 feet elevation. While that’s 5 feet lower than the lake
stood at the end of 2019, it’s still 10 feet higher than the
water level that would trigger the first major shortage,
slicing more than 520,000 acre feet of water, roughly one-third
of the state’s total supply.
The U.S. Bureau of Reclamation released projections Friday that
suggest Lake Powell and Lake Mead will dip 16 feet and 5 feet,
respectively, in January from levels recorded a year earlier.
Despite the dip, Lake Mead would stay above the threshold that
triggers severe water cuts to cities and farms, giving
officials throughout the Southwest more time to prepare for the
future when the flow will slow.
Arizona, Nevada and Mexico will again receive less water from
the Colorado River next year under a set of agreements intended
to help boost the level of Lake Mead… The federal Bureau of
Reclamation released projections Friday showing that Lake Mead,
the nation’s largest reservoir, will be at levels next year
that continue to trigger moderate cutbacks in the two U.S.
states and Mexico.
The U.S. Bureau of Reclamation is expected to release
projections Friday that suggest Lake Powell and Lake Mead will
dip slightly in 2021. … Despite the dip, Lake Mead’s levels
are expected to stay above the threshold that triggers
mandatory water cuts to Arizona and Nevada, giving officials
throughout the Southwest more time to prepare for a future when
the flow will slow.
Water-efficient succulents and nitrogen-fixing tree legumes may
take five to 12 years to produce their first nutritional
harvests. Nevertheless, they can produce more edible biomass
over a decade with far less water than that used by
conventional annual crops, while sequestering carbon into the
soil to mitigate climate change…
Hot and dry conditions pushed portions of Arizona, southern
Nevada and Southern California either into drought or further
into drought, data from the U.S. Drought monitor show. … The
North American Monsoon, which provides about half of the annual
rainfall in parts of the Southwest, has been a “nonsoon” this
year … The portion of California deemed abnormally
dry grew by almost 7%, mainly in eastern San Bernardino
County.
We deserve complete, dependable information and accurate cost
data including well-reasoned analysis that demonstrates the
need and economic viability of the pipeline. Instead, studies
by the Utah Division of Water Resources and the Washington
County Water Conservancy District are biased, incomplete and do
not fairly consider feasible, much less costly alternatives.
The average annual flow of the Colorado River has decreased 19
percent compared to its 20th century average. Models predict
that by 2100, the river flow could fall as much as 55 percent.
The Colorado River, and the people it sustains, are in serious
trouble.
The newly passed Drought Contingency Plan spurred additional
conservation and left more water in the lake. An unusually wet
year also helped, because it allowed states to fall back on
other supplies. But the fundamental problem remains: The river
still isn’t producing the amount of water we use in a typical
year. We’re still draining the mighty Colorado.
Senator Dianne Feinstein (D-Calif.) today introduced the Border
Water Quality Restoration and Protection Act, a bill to reduce
pollution along the U.S.-Mexico border and improve the water
quality of the Tijuana and New rivers.
Demonstrators in northern Mexico have burned several government
vehicles, blocked railway tracks and set afire a government
office and highway tollbooths to protest water payments to the
United States.
Legal scholars believe that the Lake Powell pipeline would
likely violate the 1922 Colorado River Compact as a
transfer of upper basin water (WY, UT, CO, NM) for lower basin
use (CA, NV, AZ). The lower basin has priority, and the compact
arguably prohibits transfers from the upper to lower basin
absent explicit congressional authorization
Imperial Beach Mayor Pro Tem Paloma Aguirre joined Good Morning
San Diego to discuss a new report claiming that an audit done

Farmers once again clashed with Mexican military forces Sunday
to protest releases of water from a dam to repay a water debt
owed to the United States. … Under a 1944 treaty, Mexico owes
the United States about 415,000 acre-feet yearly that must be
paid by Oct. 24. Mexico has fallen badly behind in payments
from previous years and now has to quickly catch up on water
transfers.
The Imperial Irrigation District and farmer Michael Abatti have
been locked in a years-long legal battle with as many twists as
the river over which it has been fought. The saga might finally
come to an end, though, after a California appellate court
handed down a ruling on Thursday that found IID is the rightful
manager of the portion of the Colorado River guaranteed to the
Imperial Valley.
The Imperial Irrigation District has filed its opening brief in
a case against the Metropolitan Water District of Southern
California that it launched last year in an attempt to halt the
implementation of the Lower Basin Drought Contingency Plan for
the Colorado River. IID wants to see it paused until the Salton
Sea is also considered.
The Consul General of Mexico in San Diego said there are things
happening in Tijuana that will help. In a written statement
responding to questions by KPBS, Carlos González Gutiérrez said
there are several projects underway.
Baja California’s new governor, Jaime Bonilla, says he is
battling to clean up widespread corruption that for years ate
away at the state’s water agency. Even Bonilla’s critics
acknowledge the corruption and the failing water system, which
results in frequent sewage spills that foul Tijuana and San
Diego beaches.
The public last week had its first opportunity to pepper
officials with questions about the Lake Powell Pipeline’s
recently-released draft environmental impact statement, a
313-page document from the Bureau of Reclamation examining how
the controversial project could impact a myriad of resources in
several scenarios.
The city of Imperial Beach, environmental advocacy group

Arizona, New Mexico, Colorado, California, Utah, Wyoming and
Nevada have been operating under a set of guidelines approved
in 2007. Those guidelines and an overlapping drought

while other states have had more informal discussions.
Passengers and employees at the Tijuana international airport
no longer have to use outside portable restrooms because the
company that operates the facility on Monday paid about $1.5
million in outstanding water bills, according to the governor.
A Baja California state water agency shut off services at the
airport last week over the years-long billing dispute.
There’s a reckoning coming, unless cities and farm districts
across the West band together to limit consumption. The coming
dealmaking will almost certainly need to involve the river’s
largest water user, the Imperial Irrigation District. But at
the moment, it’s unclear to what extent the district actually
controls the Imperial Valley’s Colorado River water. That was
the issue debated in a San Diego courtroom last week
Water pollution from Tijuana sewage runoff has once again
shuttered the Imperial Beach shoreline. The County of San Diego
Department of Environmental Health on Saturday extended north
the existing beach water-contact closure area at the Tijuana
Slough shoreline to now also include the Imperial Beach
shoreline.
Both United States and Mexican officials announced separate
plans Tuesday to upgrade Tijuana River wastewater facilities.
The international river has been a longtime problem for
residents of Imperial Beach and Tijuana, as sewage and trash
from the river have spilled into the Pacific Ocean for decades,
often closing beaches near the border and damaging natural
habitats along the river.
The County of San Diego has released a report that identifies
27 projects that could potentially reduce the flow of sewage
from Mexico into the U.S. and Tijuana River Valley each year by
as much as 91%, from 138 days to 12. The report, the Tijuana
River Valley Needs and Opportunities Assessment, identifies
strategies to manage impacts from sewage, trash, and sediment
on the U.S. side of the border.
In his time with the commission, which has the responsibility
for applying the boundary and water treaties between the United
States and Mexico, the two nations have taken huge steps
forward in assuring that commitments to the primary binational
water agreement in the Southwest – the 1944 Mexico-U.S. Water
Treaty – were faithfully upheld.
When former Interior Secretary Bruce Babbitt suggested in a
recent opinion piece that a portion of agricultural water
rights on the Colorado River should be transferred to urban
areas, it no doubt conjured up some strong emotions… But
Babbitt’s proposal makes sense and he is right about the need
to recognize the mismatch in population between the urbanized
West and rural areas where most of the basin’s water is
allocated.
EPA will convene an Interagency Consultation Group comprised of
senior-level members from key U.S. federal, state, and local
agencies, as listed in the USMCA legislation. EPA will also
manage a binational technical expert consultation process to
ensure infrastructure options are informed by the best
available technical and scientific information.
While Imperial Irrigation District has the largest right within
California, it was not the Imperial Valley that was responsible
for California’s overuse. That was the Metropolitan Water
District. We are among the very oldest users on the Colorado
River and have built a community, ecology, and way of life here
in the desert dependent upon the waters of the Colorado that
have sustained us since 1901.
Under the 1944 treaty, the US is committed to sending 1.5mn
acre-feet of water from the Colorado River basin to Mexico in
12-month periods, which represents 10% of the river’s average
flow, according to the US Congressional Research Service.
Meanwhile, Mexico must send 1.75mn acre-feet in five-year
cycles from the Rio Grande’s six major tributaries that cross
its territory.
The imbalance on the Colorado River needs to be addressed, and
agriculture, as the biggest water user in the basin, needs to
be part of a fair solution. But drying up vital food-producing
land is a blunt tool. It would damage our local food-supply
chains and bring decline to rural communities that have
developed around irrigated agriculture.
The term “crisis on the border” typically refers to immigration
issues or drugs being smuggled into the country. But it has one
more meaning, as we discovered, when we went to the border in
early February: tens of millions of gallons of raw sewage that
spill every year into the Tijuana River on the Mexican side and
flow across the border right into Southern California,
polluting the land, air, and sea.
This winter’s decent snowfall has turned into an abysmal runoff
on the Colorado River, thanks to the dry soils heading into the
winter, along with a warm spring. … Our bigger concern is
what happens next year. Are we headed for a multi-year drought?
Cornell engineers have used advanced modeling to simulate more
than 1 million potential futures – a technique known as
scenario discovery – to assess how stakeholders who rely on the
Colorado River might be uniquely affected by changes in climate
and demand as a result of management practices and other
factors.
Sprawled across a desert expanse along the Utah-Arizona border,
Lake Powell’s nearly 100-foot high bathtub ring etched on its
sandstone walls belie the challenges of a major Colorado River
reservoir at less than half-full. How those challenges play out
as demand grows for the river’s water amid a changing climate
is fueling simmering questions about Powell’s future.
As of Monday, the National Oceanic and Atmospheric
Administration’s forecast for this year’s expected water
supplies in the Colorado River is at 59% of average. That’s not
good news. If that prediction proves true, this will be one of
the driest water years since Lake Powell was constructed nearly
60 years ago.
The U.S. Environmental Protection Agency has proposed spending
$300 million to address the problem of toxic sewage flowing
across the border into San Diego County, legislators announced
Tuesday. The money would be part of the United
States-Mexico-Canada Agreement Implementation Act, and will be
used for the engineering, planning, design and construction of
wastewater infrastructure at the border, officials said.
There is a better, more equitable pathway for reducing the
deficit without forcing arbitrary cuts. It involves 3 million
acres of irrigated agriculture, mostly alfalfa and forage
crops, which consume more than 80% of total water use in the
basin. By retiring less than 10% of this irrigated acreage from
production, we could eliminate the existing million acre-foot
overdraft on the Colorado River..
While most of the Earth has been singularly obsessed with an
invisible virus from a foreign land, in this California beach
town, it’s a “crisis on top of crisis’. Not only dealing with
the creepy disease we can’t see, but a river of toxic waste
from a foreign land that we can see, but chose to ignore.
The U.S. Bureau of Reclamation released projections for the
Colorado River’s water supply for the next two years. … Lake
Mead is projected to fall into “Tier Zero” conditions for 2021
and 2022. That’s a new designation under the Drought
Contingency Plan which requires Arizona, Nevada and Mexico take
cuts in their water supply.
In the past decade, environmental groups have had success
bringing back patches of life in parts of the river delta. In
these green islands surrounded by the desert, water delivered
by canals and pumps is helping to nourish wetlands and forests.
Cottonwoods and willows have been growing rapidly. Birds have
been coming back and are singing in the trees.
If they survive to adulthood, these transplanted red-legged
frogs could help California’s state amphibian and largest
native frog west of the Mississippi River repopulate some of
the waterways where it thrived for hundreds of thousands of
years.
This report, “Scaling Corporate Water Stewardship to Address
Water Challenges in the Colorado River Basin,” examines a set
of key corporate water stewardship actions and activities, with
associated drivers and barriers, to identify how the private
sector could help tackle Colorado River water challenges.
Beaches were closed on Tuesday from the Mexico border to
Coronado as rain flushed sewage-contaminated runoff from
Tijuana into the San Diego region. “Things have gotten worse
than ever,” said Imperial Beach Mayor Serge Dedina.
The latest research about the Colorado River is alarming but
also predictable: In a warming world, snowmelt has been
decreasing while evaporation of reservoirs is increasing. Yet
no politician has a plan to save the diminishing Colorado
River.
If you followed the news about the Colorado River for the last
year, you’d think that a political avalanche had swept down
from Colorado’s snow-capped peaks and covered the Southwest
with a blanket of “collaboration” and “river protection.” I
won’t call it fake news, but I will point out errors of
omission.
The San Diego Regional Water Quality Control Board issued an
investigative order in February that requires more monitoring
of sewage-tainted cross-border flows. The order requires the
International Boundary and Water Commission to monitor more
than a dozen locations over an 18-month period.
I have long argued that a robust governance network, both
formal and informal, around the management of the Colorado
River provides the necessary conditions for managing the
problems of the river’s overallocation and the increasingly
apparent impacts of climate change. … But as we approach the
negotiation of the next set of Colorado River management rules
– a process already bubbling in the background – it is not hard
to see how my thesis could break down.
A handful of protesters marched outside the Mexican Consulate
in Little Italy, protesting cross border sewage flows. They
want Mexico to do more to fix the problem. Polluted water has
routinely flowed from Mexico into the United States since
December. “We feel like we’re not getting heard,” said Mitch
McKay, president of Citizens for Coastal Conservancy.
Climate change has dramatically decreased natural flow in the
Colorado River, jeopardizing the water supply for some 40
million people and millions of acres of farmland, according to
new research from the USGS. The decline is expected to continue
unless changes are made to alleviate global warming and the
impacts of drier, hotter temperatures.
The Colorado River’s average annual flow has declined by nearly
20 percent compared to the last century, and researchers have
identified one of the main culprits: climate change is causing
mountain snowpack to disappear, leading to increased
evaporation.
The State Lands Commission and State Controller pleaded with
the Environmental Protection Agency in a letter Friday asking
for immediate action to stop the flow of 50 million gallons per
day of polluted water into the Tijuana River Valley. That
polluted water flow has created significant and ongoing beach
closures in Imperial Beach and Coronado.
Under a 1944 treaty, Mexico and the United States are supposed
to allow cross-border flows of water to each other, but Mexico
has fallen badly behind and now has to quickly catch up on
payments. … Mexico’s federal government dispatched National
Guard officers to protect the La Boquilla dam Tuesday, but
hundreds of farmers pushed and shoved them back hundreds of
yards in a failed bid to take over the dam’s control room.
With the backing of an unusual mix of local Democrats,
Republicans, Border Patrol agents and environmental groups,
House Democrats leveraged their support for the trade bill —
one of Trump’s highest priorities — to secure the
administration’s rare backing for an environmental project.
Each group played a part.
The San Diego region has secured $300 million in federal
funding for a new U.S. facility to capture Tijuana sewage
spills before they foul South Bay shorelines, elected leaders
said Friday.
The U.S.-Mexico border delineates the separation of two
countries, but that doesn’t mean the two sides are completely
isolated from each other. … It’s also why the United States
and Mexico coordinate on public health, and why experts say the
two nations should do more on climate change.
Right now, the April-July runoff is supposed to be 82% of
average. That compares to 145 % of average in 2019, the
second-best runoff season in the past 20 years, says the
federal Colorado Basin River Forecast Center. Despite last
year’s excellent river flows, most experts also say the
Colorado still faces long-term supply issues…
The increasing spills that have polluted the Tijuana River Valley
and ocean off Imperial Beach have resulted in frustration and
anger in recent years, but also triggered broad political
collaboration at the local, state and federal level that has put
the region on the brink of real action.
Along with long-term drought and climate change, the
overcommitment of the Colorado River is a big reason why Lake
Mead has dropped to historic levels in recent years. Fixing it
could be a big problem for Arizona.
When lawmakers in the House of Representatives approved the
Trump administration’s new trade deal with Mexico and Canada
last month, they authorized $300 million to help fix failing
sewer systems that send raw sewage and toxic pollution flowing
into rivers along the U.S.-Mexico border. … But environmental
groups are condemning the new United States-Mexico-Canada
Agreement, or USMCA, saying it fails to establish binding
standards to curb pollution in Mexico’s industrial zones.
In the early years of the 20th century, leaders across the West
had big dreams for growth, all of which were tied to taking
water from the Colorado River and moving it across mountains
and deserts. In dividing up the river, they assigned more water
to users than the system actually produces.
The Lower Basin states of Arizona, California and Nevada need
to cut total water use by 18% from their 2000-2018 average to
bring Lakes Mead and Powell into a long-term state of balance,
says Brian Richter. Richter is president of the nonprofit group
Sustainable Waters and a former director and chief scientist
for the Nature Conservancy’s Global Water program.
It started with last month’s heavy rains that brought an
unprecedented volume of debris tumbling down Tijuana’s Matadero
Canyon: old mattresses, used furniture, discarded construction
material. That led to a clogged storm drain by the border
fence, authorities said, and the flooding of a nearby sewage
pump station. The resulting pool of trash and
sewage-contaminated water has now been raising fears in San
Diego.
In theory, a demand management program would pay users to
conserve in the midst of a crisis in order to boost the river’s
big reservoirs. How it would work, who would participate and
how it would be funded are still unanswered questions. Another
concern is how to make the program equitable — so it doesn’t
burden one user over another.
Passing the new North American free trade agreement would mean
millions of dollars to help upgrade sewage infrastructure on
the border, say the agreement’s backers. But an environmental
group and a local organization on the U.S.-Mexico border say
it’s not enough.
This isn’t just a problem for Mexico. These growers are the
custodians of rare varieties of maize that may hold the secret
to more sustainable agriculture. If they lay down their tools,
their crops could begin to vanish.
Federal water managers are about to start reexamining a
12-year-old agreement among Western states that laid down rules
for dealing with potential water shortages along the Colorado
River. Interior Secretary David Bernhardt said he asked the
Bureau of Reclamation to start the review at the beginning of
2020, rather than by the end of 2020, which is the deadline
under the existing agreement.

States in the U.S. West that have agreed to begin taking less
water next month from the drought-stricken Colorado River got
praise and a push for more action Thursday from the nation’s
top water official. U.S. Bureau of Reclamation Commissioner
Brenda Burman told federal, state and local water managers that
abiding by the promises they made will be crucial to ensuring
that more painful cuts aren’t required.
The new United States-Mexico-Canada trade agreement reached
Tuesday commits the federal government to provide $300 million
for the Border Water Infrastructure Program to address
pollution on the U.S.-Mexico border, including the Tijuana
River Valley region, where millions of gallons of raw sewage,
heavy metals and other contaminants regularly flow from Tijuana
to San Diego.
Arizona, Nevada and Mexico will start taking less water from
the Colorado River in January as a hard-fought set of
agreements kicks in to reduce the risk of reservoirs falling to
critically low levels. The two U.S. states agreed to leave a
portion of their water allotments in Lake Mead under a deal
with California called the Lower Basin Drought Contingency
Plan, or DCP…
Tijuana and Rosarito residents may have gotten a brief reprieve
from scheduled water shut-offs, but the delivery of water
throughout Baja California is a vulnerable system in need of
urgent repairs, state and water officials stressed this week.
Elected leaders from across South Bay San Diego announced
Tuesday a joint effort aimed at pressuring the federal
government to support a long-term fix to the sewage pollution
that routinely flows over the border from Tijuana, fouling
beaches as far north as Coronado.
As conventional wisdom has it, the states were relying on bad
data when they divided up the water. But a new book challenges
that narrative. Turn-of-the-century hydrologists actually had a
pretty good idea of how much water the river could spare, water
experts John Fleck and Eric Kuhn write in Science be Dammed:
How Ignoring Inconvenient Science Drained the Colorado River.
They make the case that politicians and water managers in the
early 1900s ignored evidence about the limits of the river’s
resources.
Through a variety of panel discussions, presentations and a
showcase of student research, the Re:Border conference is
exploring how San Diego State University and its regional
partners can contribute to innovative solutions for
water-related challenges in the transborder region.
Native American tribes, environmentalists, state and federal
agencies, river rafters and others say they have significant
concerns about proposals to dam a Colorado River tributary in
northern Arizona for hydropower.
A bi-national conference at San Diego State University was
aimed at analyzing water resources in the Baja California and
San Diego border region where challenges include cross-border
pollution and water scarcity… Experts at the Reborder 2019
conference discussed ways to improve regional access to “a
secure and reliable water supply” through wastewater treatment
and desalination.
