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
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
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.

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
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.

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.
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
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
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
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
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

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

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

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

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.

Here’s something worth celebrating: In a rare bipartisan
resolve to prevent a water crisis in the Southwest, Congress
has authorized a plan to reduce consumption from the Colorado
River – a major conservation milestone. It shows that when we
work together as Americans, we can address some of the biggest
challenges facing our nation today.
Congress passed an historic Colorado River drought deal on
Monday, which is now on its way to President Trump’s desk for
his signature. That leaves Arizona back to wrestling with water
issues that it mostly set aside during the two years it fixated

The Colorado River Basin was already running near empty before
the Trump administration approved a new deal allowing
additional extractions from one of its main tributaries. While
the administration found the deal would not have a significant

negotiations: Southern California’s Salton Sea, a public health
and ecological disaster.
If, as being widely reported, the Colorado River basin states
… ultimately decide to proceed with a Lower Colorado River

The Metropolitan Water District of Southern California on
Tuesday sealed California’s participation in a landmark
Colorado River drought management plan, agreeing to shoulder
more of the state’s future delivery cuts to prevent Lake Mead
from falling to dangerously low levels. With California signed
on, the plan can move to Congress, which must approve the
multi-state agreement before it takes effect. The MWD board
took the step over the objections of the Imperial
Irrigation District, which holds senior rights to the biggest
allocation of river water on the entire length of the Colorado.
The Metropolitan Water District is positioning itself to
shoulder California’s entire water contribution, with its board
voting Tuesday on a proposal to essentially write out of the

California is now the lone holdout on an emergency drought plan
for the Colorado River, and the other river states are turning
up the heat to get the deal done. Representatives from Nevada
and five other Western states sent a letter to California on
Saturday urging water officials there to set aside their
concerns and “and immediately and unconditionally approve” the
so-called Drought Contingency Plan.
The Colorado River’s federal managers have projected that if
dry conditions continue, they could be unable to deliver any
water at all to downstream users (including Phoenix, Tucson,
Los Angeles, and San Diego) within five years. That’s the
doomsday scenario that has led the Colorado River’s water
managers and users to the cusp of adopting the Drought
Contingency Plan, a temporary yet broad agreement to reduce
water use and ensure that the reservoirs continue to provide a
reliable water supply.
With another deadline missed Monday, the head of the Bureau of
Reclamation is now looking for the governors in the states in
the Colorado River basin to tell her what they think she should
do to keep water levels from dropping even lower. But there’s
just two weeks for them to do that.
Days after Imperial Irrigation District officials said there
had been a breakthrough in negotiations with federal
officials to commit to the restoration of the Salton Sea
in a mammoth Colorado River drought plan, a top federal
official offered a different assessment. … The
Reclamation statement said it’s up to IID to decide when they
want to join the drought plan, indicating a possible avenue for
them to join later that would not stymie the entire agreement.
Winter storms have blanketed the mountains on the upper
Colorado River with snow. But even this year’s above-average
snowpack won’t be nearly enough to make up for the river’s
chronic overallocation, compounded by 19 years of drought and
the worsening effects of climate change.
With a Monday deadline looming, the Metropolitan Water District
of Southern California has offered to break an impasse on a
seven-state Colorado River drought contingency package by
contributing necessary water from its own reserves on behalf of
the Imperial Irrigation District. It’s not help that IID is
seeking, but Metropolitan general manager Jeffrey Kightlinger
said he had no choice.

All eyes have been on the Colorado River recently with
headlines across the west announcing the progress – or lack
thereof – of the efforts of the seven basin states to reach
agreement on the Drought Contingency Plan. So is the Colorado
River in crisis? At the 2019 California Irrigation Institute
conference, Dr. Brad Udall’s keynote presentation focused on
answering that question.
During the past two decades, the federal government’s spending
on sewer projects along the U.S.-Mexico border has declined
dramatically. The decrease in funding has left a long list of
needed sewer fixes unbuilt, while raw sewage and industrial
pollution have continued to pour into the New River, the
Tijuana River and other rivers that flow across the border.
Now, Congress has started to put more money toward combating
water pollution on the border.
Arizona’s efforts to finish a Colorado River drought plan are
moving forward after leaders of the Gila River Indian
Community announced that they will proceed with their

The odds are looking increasingly poor that Arizona and other
Western states will meet a March 4 federal deadline for
wrapping up Colorado River drought plans. That’s not just
because of the ongoing conflict over a now-shelved water rights
bill for Eastern Arizona that prompted a threat from the Gila
River Indian Community to bolt this state’s drought plan. It’s
also not just because of a Southern California irrigation
district’s efforts to secure $200 million in U.S. funds to
shore up the dying Salton Sea.
Rising temperatures can lower flow by increasing the amount of
water lost to evaporation from soil and surface water, boosting
the amount of water used by plants, lengthening the growing
season, and shrinking snowpacks that contribute to flow via
meltwater. … The researchers found that rising
temperatures are responsible for 53% of the long-term decline
in the river’s flow, with changing precipitation patterns and
other factors accounting for the rest.
House Speaker Rusty Bowers on Tuesday withdrew his bill that
would repeal state laws on when farmers forfeit their water
rights — legislation that the Gila River Indian Community said
would cause it to withdraw from the multi-state drought
contingency plan. But Bowers’ move did not get the tribe to
sign the papers agreeing to provide Arizona with the 500,000
acre-feet of water it needs to make the drought plan a reality.
As awful as the constant spills from Tijuana’s broken sewage

Arizona Governor Doug Ducey steered away from the term “climate
change” in order to garner political support for the
state’s Colorado River drought plan, he indicated Friday in an
interview with a Pima Community College newspaper. In that
interview, he also avoided making any connection between
climate change and the “drier future” (his preferred phrase)
that Arizona faces. His omission bordered on a denial of the
established links between the two.

regulation at all. In Pinal County, which falls under
these groundwater rules, the return to a total reliance on
wells reflects a major turning point and raises the possibility
that this part of Arizona could again sink into a pattern
of falling groundwater levels — just as it did decades
ago, before the arrival of Colorado River water.
Gov. Stephen Roe Lewis of the Gila River Indian Community said
in a statement Thursday that a decision by House Speaker Rusty
Bowers to move forward with a contentious water bill threatens
the community’s plan to support the drought agreement. The
Gila River Indian Community’s involvement is key because it’s
entitled to about a fourth of the Colorado River water that
passes through the Central Arizona Project’s canal.
It’s all up to the Imperial Irrigation District. The fate of a
seven-state plan to address dwindling Colorado River water
supply now appears to rest squarely with the sprawling
southeastern California water district. Its neighbor to the
north, the Coachella Valley Water District, voted unanimously
on Tuesday to approve interstate agreements that would conserve
water for use by 40 million people and vast swaths of
For generations, residents of the Southern California border
town of Calexico watched with trepidation as their river turned
into a cesspool, contaminated by the booming human and
industrial development on the other side of the border in
Mexico. As Washington debates spending billions to shore
up barriers along the 2,000-mile southwest border, many
residents in California’s Imperial Valley feel at least some of
that money could be spent to address the region’s public health
The Imperial Irrigation District holds among the oldest and
largest rights to water from the Colorado River and is using
that as leverage to get what it sees as a better deal in
current drought contingency plan negotiations involving states
that draw from the river. Among the hardball tactics IID
is putting in play: A demand that the federal government
provide $200 million for efforts to bolster the beleaguered
The Colorado river crisis ought to be upsetting markets. The
U.S. waterway supports some $4 trillion in GDP and at least
$1.3 trillion in stock value across seven U.S. states. The
river was already virtually tapped out last century, and
continuing troubles have now led the federal government to step
in to help manage its water use. Yet investors have barely
caused a ripple.
Arizona and California aren’t done finishing a plan that would
establish how states in the Colorado River Basin will ensure
water for millions of people in the Southwest, said the head of
the agency running the negotiations. … One challenge
comes from the Imperial Irrigation District, a water utility
that serves the Imperial Valley in southeastern California. It
hasn’t signed California’s plan because it wants $200 million
to restore the vanishing Salton Sea, the state’s largest lake.
A major deadline just passed without unanimous agreement among
Western states over the future of the Colorado River, so the
federal government is one step closer to stepping in on the
dwindling river that provides water for 1-in-8 Americans. The
path forward has become murkier for the drought-stricken region
now in its 19th year of low water levels after a January 31
deadline failed to garner signed agreements from Arizona and
Did the goalposts just move on us? … Media reports suggest
that Reclamation is lumping Arizona with California, which
clearly did not meet the deadline, in its reasoning for taking
an action that we had all hoped to avoid. It’s easy to feel
betrayed by that, to conclude that Arizona was asked to move
mountains and then when we did, we were told it still wasn’t
All eyes were on Arizona this week as state lawmakers took a
last-minute vote on their part of the pact. They approved the
plan Thursday afternoon, just hours before the deadline, but
Arizona officials still haven’t finalized a variety of
documents. In addition, a California irrigation district with
massive river rights has yet to sign off on the
agreement. On Friday, Bureau of Reclamation Commissioner
Brenda Burman … said the agency would start the
formal legal process of soliciting comments on how it should
Communities along the Colorado River are facing a new era of
drought and water shortages that is threatening their future.
With an official water emergency declaration now possible,
farmers, ranchers, and towns are searching for ways to use less
water and survive. Third in a series.
Gov. Doug Ducey signed a drought contingency plan Thursday
afternoon, six hours ahead of the deadline set by a key federal
official for the state to act or face having its Colorado River
water supply determined by her.That came despite objections
from some legislators who questioned why the state will allow
Pinal County farmers to once again pump groundwater for their
crops and will also provide cash to help them do it.
The Bureau of Reclamation, the Interior Department’s Western
water bureaucracy that saw its dam-building heyday in the
1960s, has risen in stature once again in the Trump
administration. Reclamation has flexed its muscles on Colorado
River drought management plans… And it has been the
administration’s key player in trying to fulfill President
Trump’s campaign promise to deliver more water to California
farmers, squeezing the state and forging ahead on a dam project
California says it doesn’t want.
California’s Imperial Irrigation District will get the
last word on the seven-state Colorado River Drought Contingency
Plans. And IID could end up with $200 million to restore the
badly polluted and fast-drying Salton Sea. Thursday, as the
clock ticked toward a midnight deadline set by a top federal
official, all eyes had been on Arizona. But lawmakers there
approved the Colorado River drought deal with about seven hours
to spare. IID, an often-overlooked southeastern California
agricultural water district, appears to have thrown a
last-minute monkey wrench into the process.
Arizona lawmakers appear on track to pass a Colorado River
drought plan, with less than 30 hours to go before a critical
federal deadline. A state Senate committee voted 6-1
Wednesday evening to pass a pair of measures that outline
how the state would share looming cutbacks on the
river’s water and work with other states to take less. The
bills now head to the full Senate and House. Both chambers are
expected to pass the bills Thursday, an effort that could
stretch into the night as they rush to meet a federal deadline.
The 32-page Layperson’s Guide to the Colorado River covers the
history of the river’s development; negotiations over division
of its water; the items that comprise the Law of the River; and
a chronology of significant Colorado River events.
Warnings of doomsday on the river are nothing new. Too many
people, farms and factories depend on too little water, which
is why the Colorado now rarely flows to its end point at the
Gulf of California. The sprawling Southwest has sucked the
river dry. Yet the region has thrived in spite of the
naysayers. Until now, it appears.
The city of San Diego decided Tuesday to back California Atty.
Gen. Xavier Becerra’s lawsuit that seeks to hold the Trump
administration accountable for sewage and other toxic flows
that routinely spill over the border from Tijuana and foul
beaches as far north as Coronado. The City Council voted
unanimously in closed session on Tuesday to join the legal
action. Councilman Chris Cate was absent.
Avoiding a long-expected crisis on the Colorado River, a water
source for 40 million people, is coming down to a final few
days of frenzied negotiations. A 19-year drought and decades of
overuse have put a water shortfall on the horizon. If
California and six other states, all with deeply entrenched
interests, can’t agree on a plan to cut their water consumption
by Jan. 31, the federal government says it will step in and
decide the river’s future.
In Arizona, the Colorado River Drought Contingency Plan now
hinges on the approval of tribal nations. The plan is meant to
levy water cuts to seven Western states in order to prevent the
river and its reservoirs from reaching critical levels — but
after a state lawmaker introduced legislation that undermines
parts of the Gila River Indian Community’s water settlement,
the tribe has threatened to exit the plan. Without tribal
buy-in, Arizona’s implementation design will collapse….
Federal Reclamation Commissioner Brenda Burman has drawn a line
in the sand for Arizona and other Western states: Finish a deal
to take less water from the Colorado River by Thursday, or the
federal government will be forced to step in and decide how to
prevent reservoirs from falling to critical levels. … The
plan’s success or failure will turn on the actions of a
few key players, including leaders of the Legislature, tribes,
farmers, cities and the state’s water managers.
Arizona’s water leaders and lawmakers are running out of time
to complete the state’s Drought Contingency Plan, a
blueprint for how Arizona water users would share a likely
shortage on the Colorado River. … There are a lot of
moving parts to understand and a lot of concepts that may seem
overwhelming. Here are the things you need to know in advance
of the Jan. 31 deadline to finish the plan.
This is not quite anyone’s vision of the California dream,
popularly imagined as variations based on building a safe,
secure and successful life. … Instead, Imperial County is
emblematic of life for millions of people around the state who
live under an umbrella of bad air quality or who have
contaminated soil or lack access to clean water.
The restoration site is one of three south of the
U.S.-Mexico border, in the riparian corridor along the last
miles of the Colorado River. There, in the delta, a small
amount of water has been reserved for nature, returned to
an overallocated river whose flow has otherwise been
claimed by cities and farms. Although water snakes through
an agricultural canal system to irrigate the restoration sites,
another source is increasingly important for restoring these
patches of nature in the delta’s riparian corridor:
With the Southwest locked in a 19-year drought and climate
change making the region increasingly drier, water managers and
users along the Colorado River are facing a troubling question:
Are we in a new, more arid era when there will never be enough
The Gila River Indian Community is threatening to blow up the
drought-contingency plan because of efforts it says will
undermine its claim to water rights. House Speaker Rusty Bowers
is proposing changes to state laws in a way he said will
protect the rights of farmers in the Safford Valley who have
been “scratching it out” to water from the Gila River. But
attorney Don Pongrace, who represents the Gila River Indian
Community, said … courts have ruled those rights — and the
water that goes with it — belong to the tribe.
For decades, the New River has flowed north across the
U.S.-Mexico border carrying toxic pollution and the stench of
sewage. Now lawmakers in Washington and Sacramento are pursuing
legislation and funding to combat the problems. “I feel very
optimistic that we’re going to be able to get some things done
on the New River issue,” said Assemblymember Eduardo
With Lake Mead now 39 percent full and approaching a first-ever
shortage, Western states that rely on the Colorado River are
looking to Arizona to sign a deal aimed at reducing the risk of
the reservoir crashing. The centerpiece of Gov. Ducey’s
proposed legislation is a resolution giving Arizona Department
of Water Resources Director Tom Buschatzke the authority to
sign the Drought Contingency Plan. The package of proposed
bills also would appropriate $35 million and
tweak existing legislation to make the plan work.
The draft legislation compiled by the Department of Water
Resources looks similar to how water leaders described the
measures at a Drought Contingency Plan Steering Committee
meeting last week. … But the legislation as drafted
barely delves into the nitty-gritty details of a far more
complex intrastate agreement that Arizona water users have been
hashing out for months.
Following one of the hottest and driest years on record, the
Colorado River and its tributaries throughout the western U.S.
are likely headed for another year of low water. That’s
according to a new analysis by the Western Water Assessment at
the University of Colorado Boulder. Researcher Jeff Lukas, who
authored the briefing, says water managers throughout the
Colorado River watershed should brace themselves for diminished
streams and the decreasing likelihood of filling the reservoirs
left depleted at the end of 2018.
A proposed Colorado River drought plan that will cost well over
$100 million is just the beginning of what’s needed to protect
the over-allocated river, says Bruce Babbitt, the former
governor who rammed through Arizona’s last big water
legislation nearly four decades ago. After Gov. Doug Ducey
urged legislators to “do the heavy lifting” and pass the
proposed drought-contingency plan for the Colorado, Babbitt
said Monday that authorities will have to start discussing a
much longer-term plan immediately after it’s approved.
As the Southwest faces rapid growth and unrelenting drought,
the Colorado River is in crisis, with too many demands on its
diminishing flow. Now those who depend on the river must
confront the hard reality that their supply of Colorado water
may be cut off.
Up against a federal deadline to approve a Colorado River
drought plan — a “generational change” in Arizona water
management — four key legislators say they’re optimistic
they’ll meet it. Led by House Speaker Rusty Bowers, a Mesa
Republican, they see the Legislature as ready — finally — to
officially endorse the plan. That’s even though competing water
interest groups still have highly visible disagreements about
Gov. Doug Ducey will use his fifth State of the State speech
Monday, Jan. 14, to try to corral the votes to approve a
drought-contingency plan in the next 17 days or risk federal
intervention. “We’re in a position now where we have a sense of
urgency and focus on Arizona’s water situation,” the governor
told the business community Friday in previewing the speech
that kicks off the legislative session.
The Colorado River may not look like it, but it’s one of the
world’s largest banks. The river is not only the source of
much of the American West’s economic productivity – San Diego,
Phoenix and Denver would hardly exist without it – but its
water is now the central commodity in a complex accounting
system used by major farmers and entire states. … This
month, the nation’s largest water agency, the Metropolitan
Water District, began what amounts to a run on the bank.
With a federal deadline to sign a Colorado River drought deal
three weeks away, Arizona water managers are still
grappling with several unresolved issues that could get in the
way of finishing an agreement. The outstanding issues,
some of which are proving contentious, range from developers’
concerns about securing future water supplies to lining up
funding for Pinal County farmers to drill wells and begin to
pump more groundwater.
First, the good news: The negotiators of Arizona’s Drought
Contingency Plan have crafted the most detailed, concrete
proposal to date laying out how Arizona will deal
with expected cutbacks to its supply of Colorado
River. Now, the bad: The partial shutdown of the federal
government is squeezing these negotiators.
Gov. Doug Ducey used his second inaugural speech Monday to
exhort lawmakers and others with a claim to Colorado River
water to approve a drought contingency plan before a solution
is imposed by the Bureau of Reclamation. “It’s simple: Arizona
and our neighboring states draw more water from the Colorado
River than Mother Nature puts back,” the governor told his
audience. “And with critical shortfall imminent, we cannot kick
the can any further.”
Colorado River water managers were supposed to finish drought
contingency plans by the end of the year. As it looks now,
they’ll miss that deadline. If the states fail to do their job,
the federal government could step in. Luke Runyon, a
reporter with KUNC who covers on the Colorado River Basin
recaps what’s been happening and why it’s so important.
It has been called speculative, foolhardy and overly expensive,
but Aaron Million’s plan to pump water from the Utah-Wyoming

has fashioned a winning proposal to feed Colorado’s thirsty,
[Serge] Dedina, mayor of Imperial Beach, expressed frustration
after a pipe in Tijuana ruptured on Monday and began spilling
as many as 7 million gallons of raw sewage daily into the
Tijuana River, which feeds into the Pacific Ocean. Dedina urged
city leaders in San Diego to join a lawsuit to force the
federal government to take action.
A sewage spill that federal officials said started Monday night
south of the border continues to flood the Tijuana River with
millions of gallons of raw effluent. A ruptured collector pipe
in southeast Tijuana is leaking roughly 7 million gallons a day
of sewage into the river, according to the U.S. section of the
International Boundary and Water Commission.
The equivalent of more than six million gallons a day of raw
sewage has been spilling into the Tijuana River since Monday
night, according to federal officials. The U.S. section of the
International Boundary and Water Commission, or IBWC, said
Tuesday that counterparts in Mexico informed the agency that
the cause of the sewage leak was a ruptured collector pipe.
The Río Nuevo flows north from Mexico into the United States,
passing through a gap in the border fence. The murky
green water reeks of sewage and carries soapsuds, pieces of
trash and a load of toxic chemicals from Mexicali, a city
filled with factories that manufacture products from
electronics to auto parts.
Cross-border water pollution between Tijuana and South San
Diego is not new, but in recent years, the problem has grown
worse. The reasons are complicated: There is Tijuana’s
topography, with its steep hillsides and canyons that drain
towards the border; the factories that get away with illegal
dumping; the city’s rapid population growth, aging wastewater
infrastructure and inadequate garbage collection. In the U.S.,
funding cuts to the Environmental Protection Agency have
prevented improvements to the Borderlands’ sewage system.

A group of powerful Imperial Valley farmers and their
irrigation district need to work together for the benefit of
the region, according to Superior Court Judge L. Brooks
Anderholt. He warned a fight between the two sides over rights
to Colorado River water and the need to address a prolonged
drought across the Southwest could spur action by Congress, or
end up in the U.S. Supreme Court.
It’s hard to find a bucket, pail or plastic receptacle in this
city of millions that isn’t full of water. That’s no
exaggeration. Sales of buckets and plastic containers have been
sky high as residents prepare for the Great Water Cut-off, or
Megacorte that’s hit Mexico City.
Still officially listed as endangered, the olive ridley has
nonetheless made a spectacular recovery. … While the species
still faces threats such as floating fishing tackle, climate
change, beach erosion, plastic and other sources of pollution,
biologists say the upswing in nests here is a clear sign that
the reptile’s numbers may be stabilizing, if not increasing.
Experts called on Mexico’s government Wednesday to use floating
barriers to enclose a small area of the Gulf of California
where a half dozen critically endangered vaquita porpoises were
spotted in September.
Wastewater flowing from Mexico into Arizona fills a stretch of
the lower Santa Cruz River through the state’s southern
desert—but keeping the water clean and sewer pipe repaired
rankles both sides of the border. The 8.5-mile sewer pipeline
has caused issues for at least a decade and leaked raw sewage
last year, prompting Gov. Doug Ducey ® to briefly declare a
state of emergency.
It’s the rainy season now in Mexico. … Despite the rainfall,
for five months of the year, many of the metropolitan area’s
more than 20 million residents don’t have enough water to
drink. Nearly all that rainwater runs off the streets and
highways into the city’s massive drainage system built to stave
off perennial flooding.
California Atty. Gen. Xavier Becerra filed a lawsuit Tuesday
night against the Trump administration, alleging that the

on the International Boundary and Water Commission.
A lawsuit brought by South Bay cities alleging the federal
government is not doing enough to prevent and treat the flow of
Tijuana sewage into the U.S. can move forward, a San Diego
federal judge ordered this week. The ruling, filed Wednesday,
comes a day after U.S. District Judge Jeffrey Miller toured
pumps and water-capture basins in the Tijuana River Valley to
get a first-hand look at the issue.
Federal court judge Jeffrey T. Miller toured the Tijuana River
Valley for several hours on Tuesday to observe pumps and canyon
collectors along the border intended to prevent sewage from
spilling into San Diego. The unusual move comes as the result
of a contentious legal battle in which Miller must decide
whether the Trump administration is doing enough to stop sewage
that routinely pours into the United States from Mexico.
California farmers are poised to receive hundreds of millions
of dollars worth of aid from the U.S. Department of Agriculture
to help offset the impact of rising tariffs. But most of the
state’s top agricultural exports will not receive direct cash
payments, as they and members of the state’s congressional
delegation had pushed for.
All along the 1,250 miles of border between Texas and Mexico,
hidden under hundreds of feet of soil and rock, lie more than a
dozen underground aquifers—areas of permeable earth that hold
water—that crisscross the national boundaries. They might be
the only sources of water the region will have left when the
Rio Grande, hit by a one-two punch of climate change and a
booming population, inevitably dries up.
Florida and Mexico are having a food fight over tomatoes and
other fresh produce. Will farmers in California and Washington
get caught in the crossfire? That’s one question that swirls
around the final negotiations between the Trump administration
and Mexico on a revamped North American Free Trade Agreement.
To protect one of the most endangered species in the world, an
international trade court judge ordered the Trump
administration Thursday to ban all seafood harvested with gill
nets in Mexico’s northern Gulf of California — a bold move with
significant political and economic consequences.
For Americans, what probably matters most in this story are the
strawberries. For most Mexicans in the northern Baja peninsula,
what matters is the robust economy strawberries bring. For
some, what matters most is the steady loss of the fresh

Nowhere is the domino effect in
Western water policy played out more than on the Colorado River,
and specifically when it involves the Lower Basin states of
California, Nevada and Arizona. We are seeing that play out now
as the three states strive to forge a Drought Contingency Plan.
Yet that plan can’t be finalized until Arizona finds a unifying
voice between its major water players, an effort you can read
more about in the latest in-depth article of Western Water.
Even then, there are some issues to resolve just within
It’s high-stakes time in Arizona. The state that depends on the
Colorado River to help supply its cities and farms — and is
first in line to absorb a shortage — is seeking a unified plan
for water supply management to join its Lower Basin neighbors,
California and Nevada, in a coordinated plan to preserve water
levels in Lake Mead before
they run too low.
If the lake’s elevation falls below 1,075 feet above sea level,
the secretary of the Interior would declare a shortage and
Arizona’s deliveries of Colorado River water would be reduced by
320,000 acre-feet. Arizona says that’s enough to serve about 1
million households in one year.
Rescuers searching Tuesday for seven people missing after a dam

pollution has been part of Imperial Beach life for generations,
particularly for the surf community.
The state Attorney General has joined San Diego’s regional
water regulators in pressuring the White House to do more to
address sewage from Tijuana that routinely spills over the
border fouling beaches as far north as Coronado. The San Diego

Attorney General Xavier Becerra’s office, on Monday filed a
60-day notice of intent to sue the federal government for
violations of the Clean Water Act.
The top United States official at the international agency
charged with overseeing efforts to stem ongoing water pollution
in the Tijuana River Valley stepped down on Friday. The

Sin City has never been a place that thinks small. So it should
come as no surprise that Las Vegas – about 300 miles from the
Pacific Ocean – is pondering seawater desalination to meet its
long-term water demand. That doesn’t mean Vegas plans to build
a pipeline to the ocean. More likely, it would help pay for a
desalination facility in a place like Mexico, then trade that
investment for a piece of Mexico’s water rights in the Colorado
A plan to pipe treated wastewater from Tijuana to the Guadalupe

Members of the San Diego Regional Water Quality Control Board
gathered in a closed session on Monday afternoon, debating
whether to file a lawsuit against the federal government to
stem the cross-border flow of sewage, sediment and other

The problem with focusing on Trump’s pipe dream of a wall is
that real border problems that can actually be solved are being
ignored. The Tijuana River, for instance, which crosses the

side, is said to be one of the most polluted waterways in the
Not if, but when. That’s the future of water desalination
plants in Arizona, according to the head of the state’s water
department. They are controversial and expensive, but Arizona’s
current leadership views desalinated water – or “desal” – as
key to the state’s long-term water plans. Arizona sits atop an
estimated 600 million acre-feet of brackish water.
As executive director of the environmental group Wildcoast,
[Imperial Beach Mayor Serge] Dedina has led a years-long fight
by his city to sue the federal government for failure to

a “tsunami” of raw sewage, toxic sludge and solid waste that
spills through the border region via the Tijuana River Valley,
threatening the health of millions.
With health complaints continuing from Border Patrol agents who
work the polluted areas of the Tijuana River Valley, the
federal Customs and Border Protection agency is quietly trying
to solve some of the problems of toxic sewage flows from Mexico
— on its own.
In the wake of rising outcry in San Diego of cross-border flows
of contaminated water, trash and sediment from Tijuana, Mexico
is moving ahead with a series of short-term upgrades to
Tijuana’s sewage collection and treatment system aimed at
preventing such incidents, and responding with greater speed
should they occur.
The cities of Imperial Beach and Chula Vista and the Port of
San Diego said the International Boundary and Water
Commission’s U.S. section has failed to meet obligations under
the federal Clean Water Act to treat the runoff from Tijuana,
allowing toxins and bacteria to spread in the Tijuana River
Valley and out to the Pacific Ocean.
South Bay elected officials said they are filing a lawsuit
