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.
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…
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.
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.
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.
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.
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.
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…
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.
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.
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.
Imperial Beach Mayor Pro Tem Paloma Aguirre joined Good Morning
San Diego to discuss a new report claiming that an audit done
by Baja California governor accuses big US companies of water
theft and contributed to raw sewage and hazardous pollutants
ending up in the Tijuana River.
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
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.
An independent audit of Baja California’s water agency alleges
that former employees of the utility colluded with
international corporations to defraud the state out of at least
$49.4 million… Local and international corporations —
including such well-known U.S. names as Coca-Cola, FedEx and
Walmart — for years took water for their Mexican factories,
retail stores and distribution centers without fully paying for
it…
Researchers in the Grand Canyon now spend weeks at a time,
several times a year, monitoring humpback chub, which has
become central to an ecosystem science program with
implications for millions of westerners who rely on Colorado
River water.
The city of Imperial Beach, environmental advocacy group
Surfrider Foundation and the San Diego Regional Water Quality
Control Board agreed to put down their proverbial legal swords
for a period of 12 months while the U.S. Environmental
Protection Agency puts a stack of cash to work on the
decades-long sewage issue plaguing the Tijuana River watershed.
An independent audit of Baja California’s water agency alleges
that former employees of the utility colluded with
international corporations to defraud the state out of at least
$49.4 million, according to an auditor and the governor of the
state.Local and international corporations — including such
well-known U.S. names as Coca-Cola, FedEx and Walmart — for
years took water for use in their Mexican factories, retail
stores and distribution centers without fully paying for it,
Baja California officials have alleged.
The state of California, city of Imperial Beach, and the
Surfrider Foundation have agreed to a 12-month stay in
litigation over cross-border sewage flowing in from Mexico
while the U.S. Environmental Protection Agency focuses work on
the Tijuana River Valley.
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
contingency plan will expire in 2026. Arizona water officials
are gathering Thursday to start talking about what comes next,
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.
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.
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.
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.
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.
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.
Water shutoffs aren’t uncommon in the growing cities of Tijuana
and Rosarito. But they’re rarely announced beforehand, and
they’re often isolated to certain neighborhoods after pipes or
pumps fail. Earlier this month, however, Tijuana officials
announced that it was planning wide-ranging shutoffs for the
next two months, in an attempt to replenish a vital reservoir
that is perilously low.
Ambiguity exists in the language of the river’s foundational
document, the Colorado River Compact. That agreement’s language
remains unclear on whether Upper Basin states, where the
Colorado River originates, are legally obligated to deliver a
certain amount of water over a 10-year period to those in the
Lower Basin: Arizona, California, and Nevada.
Declining flows could force Southwest water managers to
confront long-standing legal uncertainties, and threaten the
water security of Upper Basin states of Colorado, Wyoming, Utah
and New Mexico.
The problem in the 1920s was neither the lack of good science
nor the inability of decision-makers to understand the basin’s
hydrology. … In an era driven by politics of competition for
a limited supply of river water and federal dollars, those
decision-makers had the opportunity to selectively use the
available science as a tool to sell their projects and vision
for the river’s future to Congress and the general public.
Arizona’s portion of the Drought Contingency Plan became a
unique example in the basin of tribal leaders asserting
themselves in broader discussions about the river’s management.
… With the drought plan done, some tribal leaders say their
water rights can’t be ignored any longer.
Here’s the nut: Water supply in the Colorado River could drop
so far in the next decade that the ability of the Upper
Colorado River Basin states – Colorado, Utah, Wyoming, and New
Mexico – to meet their legal obligations to downstream users in
Nevada, Arizona, California, and Mexico would be in grave
jeopardy.
Starting Monday, authorities in Tijuana and Rosarito will
ration water for the next two months because of a limited
supply, according to the Baja California Public Service
Commission. Roughly 140,000 households and business in the
border cities will go without water service for up to 36 hours
every four days.
Jaime Bonilla was sworn into office Friday as governor of
California’s neighboring Mexican state. … In his first major
speech since taking office, Governor Bonilla promised to
address poverty, public safety issues and end cross-border
sewage flows within six months. Bonilla, a dual U.S.-Mexico
citizen, formerly served as an elected member of the Otay Water
District in Chula Vista.
Mexico says it will rehabilitate five pumping stations in the
border city of Tijuana to prevent cross-border sewage spills
that have angered U.S. communities in the San Diego area.
It was on the Colorado River that González, now 82, taught her
children, just like her parents and grandparents taught her, to
fish with canoes and traps made from willow trees which
flourished on the riverbanks. Now, the river stops at the
US-Mexico border and the lakes are dry and native vegetation is
confined to reforestation projects.
The Colorado River serves over 35 million Americans before
reaching Mexico – but it is dammed at the border, leaving
locals on the other side with a dry delta.
The Senate approved almost $20 million in funding to address
sewage flows along the border. Sen. Dianne Feinstein, who
secured language in three different appropriations bills for
the 2020 fiscal year, called the spills that send millions of
gallons of raw sewage from Tijuana to San Diego,
“unacceptable.”
Pulling weeds is not usually a great way to start a party. But
filling a dumpster with invasive species was just the right
activity to commemorate the 10th anniversary of Tijuana River
Action Month on Saturday.
Lake Powell’s long decline may be on hiatus after this year’s
snowy winter, but activists still are raising concerns that
climate change could render Glen Canyon Dam inoperable. This
time, they are taking their concerns to court, asking a federal
judge to invalidate the federal Bureau of Reclamation’s 20-year
operating plan for the towering dam..
We now have an opportunity to build on the successful Arizona
process that led to the DCP signing. Arizona is stronger
together. And that will serve us well as we work toward the
next step – maintaining a stable, healthy Colorado River system
as we face a hotter and drier future.
The United States-Mexico border region is enduring the latest
in a series of massive cross-border sewage tainted spills.
Federal officials in charge of monitoring the trans-border
sewage situation on the U.S. side of the border said nearly 8
million gallons of tainted water flowed across the border in
the Tijuana River channel.
Senate Bill No. 690 seeks to reduce exposure to dangerous
pathogens, limit beach closures and address water quality
issues in the Tijuana River Valley. The bill will also allow a
$15 million budget allocation for cleanup efforts as well as
prioritizing projects that will address water quality, flood
control, trash and sediment.
There was more buzz this week at two big Colorado River Basin
events about the idea of a “grand bargain” to deal with coming
collisions between water overallocation and the Law of the
River.
The mayor of this beach town, which abuts Tijuana, Mexico at a
point that is visible by a border wall marking the two
countries, is fed up with sewage and toxic chemicals flowing
into the United States, and he is heading to Washington, D.C.,
to ask the Trump administration to do something about it.
Tijuana’s sewage system appears to be incapable of handling the
sewage generated in the Mexican city, and Imperial Beach Mayor
Serge Dedina called the situation unacceptable. Dedina hoped to
get the attention of President Donald Trump, who is in San
Diego on Wednesday for a fundraiser.
The Colorado River Basin’s 20 years of drought and the dramatic
decline in water levels at the river’s key reservoirs have
pressed water managers to adapt to challenging conditions. But
even more extreme — albeit rare — droughts or floods that could
overwhelm water managers may lie ahead in the Basin as the
effects of climate change take hold, say a group of scientists.
I’ve spent half a day tormented by a problem that has already
tormented me many times before in my career: Where can one find
a Colorado River Basin map that is accurate? It seems like such
a simple task, but as others have noted before, it is an
ongoing problem. The list of problem areas is long, and many
seem to have a strong political motivation.
However, this is brackish water. For a few months we will see
it in the Colorado below Morelos Dam, reminding us of the river
that once flowed there. It is agricultural drainage that comes
from farms in southwestern Arizona that use the Colorado River
to irrigate in the desert.
The only bi-national financial institution dedicated to funding
environmental infrastructure projects along the border unveiled
six possible solutions to slowing down the cross-border sewage
spills that routinely shut down southern San Diego’s beaches.
Water users in the Colorado River Basin have survived the
drought through a combination of water storage infrastructure
and voluntary actions to protect reservoir storage and water
supply. Adoption of drought contingency plans this summer,
developed over years of collaborative negotiation, takes the
next step by implementing mandatory action to reduce risk and
protect limited water supplies.
ASU Now spoke to Sarah Porter, director of the Kyl Center for
Water Policy at ASU’s Morrison Institute for Public Policy,
about the cutbacks and what they will mean for Arizona’s
agriculture and the state’s roughly 7 million residents.
The Colorado is the most significant water supply source in the
West, but it carries an annual salt load of nine to 10 million
tons, said Don Barnett, executive director of the Colorado
River Basin Salinity Control Forum. … For the past 40 years,
the the forum has been “silently working away” at improving
water quality and lowering salt content on the Colorado, which
supplies water to 40 million people in seven states and Mexico.
Rocky Mountain water managers worried about climate-driven
depletion across the Colorado River Basin are mulling a “grand
bargain” that would overhaul obligations among seven
southwestern states for sharing the river’s water. This
reflects rising concerns that dry times could turn disastrous.
Just a few months after completing the Drought Contingency Plan
for the Colorado River states, water managers in the southwest
will likely have to implement it starting in 2020. That’s
according to new projections for the levels of key reservoirs
in the southwestern river basin, and Arizona is first in line
to take water cutbacks.
Arizona, Nevada and Mexico will be required to take less water
from the Colorado River for the first time next year under a
set of agreements that aim to keep enough water in Lake Mead to
reduce the risk of a crash.
With big western cities clamoring for a share of the
river’s diminishing supply, desert farmers with valuable claims
are making multimillion dollar deals in a bid to delay the
inevitable. … But if the river’s water keeps
falling, more radical measures will be needed to protect
what remains.
The U.S. Bureau of Reclamation on Thursday will release its
projections for next year’s supply from Lake Mead, a key
reservoir that feeds Colorado River water to Nevada, Arizona,
California and Mexico. After a wet winter, the agency is not
expected to require any states to take cuts to their share of
water. But that doesn’t mean conditions are improving long
term.
The recently adopted Drought Contingency Plan (DCP) was an
important step toward addressing the Colorado Basin’s chronic
water shortages, but more work is needed to prepare for a
hotter, drier future. We talked to Doug Kenney, director of the
Western Water Policy Program at the University of Colorado and
a member of the PPIC Water Policy Center research network,
about managing the basin for long-term water sustainability.
Customs and Border Protection commissioned a six-month study,
published earlier this year, of 42 samples from the river and
two culverts during dry, wet, post-rain, and standing water
conditions. … Justin Castrejon, a Border Patrol agent and
regional spokesman, said the report validated the claims of
agents who have complained of physical health ailments after
patrolling the affected areas.
San Diego County officials are finalizing a list of projects
that could help fix the region’s sewage problems. Sewage flows
from Tijuana regularly foul San Diego’s ocean waters. That
prompted the state, the Port of San Diego, a clean water group
and several municipalities to sue the federal government to fix
the problem.
The solution lies in filling the sea with water. But what
source would produce enough water to cover the lakebed (playa)
years into future years? Where would we get such huge
quantities of fresh or salt water? There is but one realistic
source: the Sea of Cortez.
Described in a comprehensive new study published Wednesday in
the journal Science Advances, scientists now understand the
causes of the megadroughts common during the medieval period.
With climate change, they predict more megadroughts in the
future.
Water managers on the Colorado River are facing a unique
moment. With a temporary fix to the river’s scarcity problem
recently completed, talk has begun to turn toward future
agreements to manage the water source for 40 million people in
the southwestern U.S. … Some within the basin see a window of
opportunity to argue for big, bold actions to find balance in
the watershed.
Today, Rep. Juan Vargas (CA-51) along with Reps. Susan Davis
(CA-53), Scott Peters (CA-52), and Mike Levin (CA-49), hosted a
press conference to announce the introduction of their Tijuana
River Valley Pollution Solution bill package. The combined
legislation would further support mitigation efforts in the
region.
The state drought plans move gingerly toward encouraging
transfers of water by using clever euphemisms that avoid any
mention of water marketing. … These euphemisms are tools that
usher in a new frontier in western water law that will increase
resilience in the face of droughts, floods and forest fires
fueled by climate change.
In black and white, John Trotter documents the use of water
from the Colorado River, tackling the social, political, and
environmental impact of the way it’s dealt with. Spanning over
years and kilometres, his ongoing essay is a dire political
outcry.
Despite being on opposite sides of the immigration debate,
environmental groups who oppose border barriers generally
mirror cattle rancher John Ladd’s concerns about the river.
They say a wall or fence across the San Pedro could have
devastating consequences to its hydrology, as well as the
endangered species that call the river home.
The plan is historic: It acknowledges that southwestern states
need to make deep water use reductions – including a large
share from agriculture, which uses over 70% of the supply – to
prevent Colorado River reservoirs from declining to critically
low levels. But it also has serious shortcomings. It runs for
less than a decade. And its name suggests a response to a
temporary problem.
Only one undammed river in the American Southwest still flows
freely, and it begins just south of the border, in Sonora,
Mexico. From there, the San Pedro River courses north into
Arizona, a rare and unbarricaded corridor that is a haven and
vital water source for a vast array of plants and wildlife…
The unusually wet winter (with an assist from new Colorado
River Drought Contingency Plan water reduction rules) has
substantially reduced the near-term scare-the-crap-out-of-me
risks on the Colorado River for the next few years, according
to new Bureau of Reclamation modeling.
From sea to shining sea may take on a new meaning in
California, as state officials are reviewing billion dollar
plans to import water from Mexico’s Sea of Cortez to help raise
water levels at the Salton Sea.
It will take as many as 13 water years exactly like this one to
erase the impacts of long-term drought in the West, Colorado
River District engineers say.
In the long-term puzzle of ensuring that the Colorado River —
the main artery of the American West — provides water to the
millions of people in the basin who depend on it, the
challenges are mounting. Does 2019’s water stand a chance of
making a meaningful impact? Water experts say the answer is:
Sadly, not likely.
The Lower Basin will not drop into a Tier One shortage next
year because Lake Mead will almost certainly remain above 1,075
feet in elevation. At the same time, Mead will likely remain
under 1,090 feet. That triggers a Tier Zero shortage. “Under
Tier Zero conditions, Arizona takes a reduction of 192,000
acre-feet in its annual Colorado River entitlement,” said
Suzanne Ticknor, assistant general manager at the Central
Arizona Project.
Leaving more water in the Colorado River Basin could help
rivers resume their natural role. But amid this push for upper
basin residents to use less, Colorado’s booming Front Range
economy is driving cities in the opposite direction: of
manipulating rivers more by installing new dams, reservoirs and
diversions.
The Colorado River Drought Contingency Plan, divided into plans
for the river’s upper and lower basins, is the product of years
of interstate negotiations, business transactions and political
dealings. What, though, does it mean for Nevada and other
Western states as a whole?
Most of the seven states that get water from the Colorado River
have signed off on plans to keep the waterway from crashing
amid a prolonged drought, climate change and increased demands.
But California and Arizona have not, missing deadlines from the
federal government.
The states that share the river completed a drought plan
earlier this year that brings them closer to living within
currently available supplies, and a new round of negotiations
on long-term management of the river is due to begin next year.
However, a new report warns that planning for gradually
declining water supplies, as difficult as that is, may not be
enough to adequately prepare for the future.
The question of whether the Colorado River system is a reliable
source of water for the future was the topic of a presentation
held at the Washington County Water Conservancy District on
Thursday. … Utah is entitled to 23%, or about 1.4 million
acre feet under the compact. Utah currently uses 1 million acre
feet, Millis said. This leaves the state with 400,000 acre feet
to left to develop.
States that share the river’s water finalized a big agreement
last month, but an even larger challenge determining the
river’s future is just around the bend, expert John Fleck
explains.
A local advocacy group held a rally Sunday morning calling on
the federal government to stop the pollution of coastal waters
caused by untreated sewage from the Tijuana River Valley.
Rather than unquestioningly celebrating Powell and his legacy,
this year gives us the chance to think about a couple of
points: First, how are we telling Powell’s story now, and how
have we told it in the past? Is it, and has it been, accurate
and useful? Second, whose stories have we excluded, ignored,
and forgotten about in the focus on Powell?
I ran down a quick summary this morning of the relevant data,
comparing recent use with the cuts mandated under the DCP. It
shows that, at this first tier of shortage, permitted use is
less than the voluntary cuts water users have been making since
2015. In other words, all of the states are already
using less water than contemplated in this first tier of DCP
reductions.
The Colorado River just got a boost that’s likely to prevent
its depleted reservoirs from bottoming out, at least for the
next several years. Representatives of seven Western states and
the federal government signed a landmark deal on Monday laying
out potential cuts in water deliveries through 2026 to reduce
the risks of the river’s reservoirs hitting critically low
levels.
The Colorado River — of which the Green is the biggest
tributary — is the main water source for 40 million people.
It’s already overallocated, and climate change is predicted to
shrink flows by up to 50 percent by the end of the century.
We’re finally coming to grips with those forecasts and
beginning to heed Powell’s century-and-a-half-old warnings. But
it’s taken drought and desperation to get us there, and we have
to do better.
After months of tense, difficult negotiations, a plan to spread
the effects of anticipated cutbacks on the drought-stricken
Colorado River is nearing completion. On Monday,
representatives of the seven states that rely on the river will
gather for a formal signing ceremony at Hoover Dam, the real
and symbolic center of the Lower Basin Drought Contingency
Plan.
It takes more than one wet year to not only refill reservoirs
but also recharge aquifers and return moisture in parched soils
to normal levels. … All this upstream snowpack and rain is
predicted to boost Powell to 47% of capacity by the end of the
year, another three or four feet, but there’ll still be plenty
of the “bathtub ring” visible. It’s been 36 years since Powell
was full. It’s not likely it’ll ever fill again.
Stakeholders throughout the Colorado River Basin just wrapped
up arduous negotiations on a drought plan. There’s little time
to rest, however. Stakeholders are expected to begin the even
more difficult task of hammering out sweeping new guidelines
for delivering water and sharing shortages that could
re-imagine how the overworked river is managed.
This river provides water for one-third of Latinos in the
United States. Latinos make up the bulk of agricultural workers
harvesting the produce this river waters. We boat, fish, swim
and recreate along its banks. We hold baptisms in its waters.
Therefore, it is critical to engage the growing Latino
population on water-smart solutions.
The DCP … provides assurance against curtailments for water
stored behind Hoover Dam. This is especially important for the
Southern California water agencies, whose ability to store
water in Lake Mead is crucial for managing seasonal demands.
Some significant challenges must still be addressed, however.
People who live along the southern border all say the same
thing: When it rains, it stinks. The reason is a failing, aging
network of pipes that run from Mexico to wastewater treatment
plants in the U.S. When heavy rains fall, the pipes often break
and spill raw sewage on both sides of the border, causing not
only a putrid odor but public health and environmental
concerns.
Set to expire in 2026, the current guidelines for water
deliveries and shortage sharing, launched in 2007 amid a
multiyear drought, were designed to prevent disputes that could
provoke conflict. … But as the time for crafting a new set of
rules draws near, some river veterans suggest the result will
be nothing less than a dramatic re-imagining of how the
overworked Colorado River is managed…
According to the Bureau of Reclamation, the snowpack in the
Upper Basin is nearly 140% above average as of April 15 and it
forecasts that seasonal inflow to Lake Powell will be at 128%
of average. … “These developments may lessen the chance of
shortage in 2020,” Terry Fulp, BOR’s Lower Colorado regional
director, said in a prepared statement.

The giant reservoir, formed by Glen Canyon Dam, was under 40
percent full the last week of April. And a lot of water is
still being released from the reservoir, more demands on the
water are expected, and the water supply above the reservoir,
in the sprawling Colorado River system, is expected to
decrease.
DCP puts safeguards in place to help manage water use now and
better deal with a potential shortage. Utah, Arizona and the
five other Colorado River basin states wisely chose to include
conservation measures in the DCP — and shared in their
sacrifice to avoid costly litigation and imposed cuts. Congress
and the states should be commended for this bipartisan,
collaborative process.
A group of Democratic senators and San Diego County-based
congressional representatives sent a letter to multiple federal
agencies Tuesday urging them to address sewage runoff in the
Tijuana River … Local and state officials as well as
environmental activists have decried the condition of the
Tijuana River for years, which regularly causes beach closures
along the county’s coastline, particularly after heavy rain.
Some lawyers say the Drought Contingency Plan, or DCP, may be
built on shaky legal ground and could be vulnerable to
litigation — depending on how the Bureau of Reclamation
implements it. One California water district has already sued
to block it.
The Colorado River Sustainability Campaign has been an
important behind-the-scenes player for environmentalists
working on the waterway, which provides water to 40 million
people. … When asked who funds his project, Sam Tucker listed
five foundations. Those foundations’ grant databases showed
that his campaign has received at least $8.6 million since
2016. … Almost half — $4 million — of the campaign’s money
came from one source: the Walton Family Foundation. (Second of
two parts.)
Arizona’s top water official says a lawsuit filed Tuesday by
California’s Imperial Irrigation District could pose a threat
to the newly approved multistate drought contingency plan. But
Tom Buschatzke, director of the Department of Water Resources,
said he’s not worried the plan will fall apart — at least not
yet.
The petition, filed in Los Angeles Superior Court,
alleges violations of the California Environmental Quality
Act by the Metropolitan Water District of Southern California,
and names the Coachella Valley, Palo Verde and
Needles water districts as well. It asks the court to
suspend the Lower Basin Drought Contingency Plan until a
thorough environmental analysis has been completed.
There are at least six high-profile projects in Utah, Colorado,
and Wyoming that combined could divert more than 300,000
acre-feet of water from the beleaguered Colorado River. That’s
the equivalent of Nevada’s entire allocation from the river.
These projects are in different stages of permitting and
funding, but are moving ahead even as headlines about the
river’s dwindling supply dominate the news.
An unlikely advocate seems to be around every bend of the
Colorado River these days: the Walton Family Foundation. The
$3.65 billion organization launched by Walmart founder Sam
Walton has become ubiquitous in the seven-state basin that
provides water to 40 million people, dishing out $100 million
in grants in the last five years alone. … The foundation’s
reach is dizzying and, outside the basin, has received scant
attention. (First of two parts.)
A new study released by the U.S. Bureau of Reclamation predicts
a release of up to 9 million acre-feet of water from Lake
Powell to Lake Mead this year, which means a possible shortage
declaration looming in 2020 might be averted. The snowpack in
the Colorado River Basin is about 130 percent of average, with
flows into Lake Powell predicted to be 128 percent of average
during the runoff season.
President Donald Trump signed a bill Tuesday authorizing a plan
for Western states to take less water from the overburdened
Colorado River. The president’s signing capped a years-long
process of sometimes difficult negotiations among the seven
states that rely on the river. … Next, representatives from
Arizona and the other Colorado River basin states who had a
hand in crafting the deal are expected to meet for a formal
signing ceremony.
