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.
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.
The Colorado River has been dammed, diverted, and slowed by reservoirs, strangling the life out of a once-thriving ecosystem. But in the U.S. and Mexico, efforts are underway to revive sections of the river and restore vital riparian habitat for native plants, fish, and wildlife. Last in a series.
The strategy of turning to groundwater pumping will test the limits of Arizona’s regulatory system for its desert aquifers, which targets some areas for pumping restrictions and leaves others with looser rules or no 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.
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 agricultural lands.
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.
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 threats.
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 Salton Sea.
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 California.
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 good enough.
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 impose cuts.
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.
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 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.
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.
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.
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.
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.
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.
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.
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: groundwater.
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.
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 water?
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 Garcia.
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.
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.
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.
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.
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.
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 it.
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.”
Arizona must identify our next bucket of water. Championing desalination along the California coastline is one long-term solution that can help secure Arizona’s economic and water future.
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 border to Colorado’s Front Range just won’t dry up. Now seeking water rights from the Green River in Utah for a new version of his plan, Million thinks he has fashioned a winning proposal to feed Colorado’s thirsty, growing population.
[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.
Mexico’s demand for natural gas is expected to grow by as much as 10 percent over the next few years, but unlike in the U.S., fracking isn’t expected to help meet much of that demand.
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 federal government violated the Clean Water Act by allowing, in recent years, millions of gallons of raw sewage, heavy metals and other contamination to routinely spill from Tijuana into San Diego.
A top Nevada water and power official has been tapped by the Trump administration to lead the International Boundary and Water Commission for the United States and Mexico. The White House on Friday announced plans to appoint Jayne Harkins, executive director of the Colorado River Commission of Nevada, to head up the U.S. side of the cross-border treaty organization.
The White House plans to nominate Jayne Harkins, head of the Colorado River Commision of Nevada, to represent United States’ international interests related to the Colorado and Rio Grande rivers, both shared with Mexico. In a statement, the White House said it would nominate Harkins as the U.S. Commissioner 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 groundwater that makes strawberries possible here. The San Quintín valley, an arid region 180 miles south of Tijuana, is the crossroads where strawberries, economics, and groundwater meet.
In the rivers of southern Mexico, a lizard-like fish with armor for skin has taken over the habitat of the native fish like róbalo and mojarra. Locals call it the pez diablo, or devil fish, and long assumed it was poisonous.
Coronado’s mayor flew to Oklahoma this week to talk with the head of the Environmental Protection Agency about possible solutions to the recurring Tijuana sewage spills that sully the San Diego County coastline. Mayor Richard Bailey and Administrator Scott Pruitt spoke one-on-one for about 20 minutes Tuesday during an annual meeting between leading environmental experts and regulators from Mexico, the United States and Canada.
The Trump administration has appointed Republican Mike Stoker for the position [Environmental Protection Agency Region 9 administrator]. … KQED Science recently spoke with him at his office in San Francisco. He said a top priority for him is to deal with sewage pollution at the US-Mexico border.
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 California.
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 containing mineral tailings burst at a mine in the northern Mexican border state of Chihuahua found one body that was not yet identified, state officials said.
Mexican President Enrique Pena Nieto has issued a series of decrees establishing water reserves, aiming to preserve sufficient supplies for tens of millions of people.
Last year, after more than 250 gallons of sewage spilled into the Pacific Ocean from the Tijuana River, water pollution in Imperial Beach became an international story. … Although the spills have come to the forefront in the last few years, water 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 Regional Water Quality Control Board, with the backing of 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 departure of Edward Drusina, former commissioner of the U.S. section of the International Boundary and Water Commission, or IBWC, comes as the agency continues to face legal attacks from South Bay cities that routinely shutter beaches due to pollution from south of the border.
A swarm of small earthquakes hit a town near the U.S.-Mexico border Saturday and continued into Sunday. Dozens of quakes were reported in and around Ocotillo Wells in Imperial County, six of them larger than a magnitude 3, according to the U.S. Geological Survey.
The river is so foul that rumors swirl about two-headed turtles and three-eyed fish. If you fall in, locals joke, you might sprout a third arm. So go the stories about the New River, whose putrid green water runs like a primordial stew from Mexico’s sprawling city of Mexicali through California’s Imperial Valley.
[Rep. Susan] Davis, a San Diego Democrat on the House Armed Services Committee, has grown concerned about untreated sewage leaking from Tijuana’s aging and overworked wastewater collection and treatment system, a problem exacerbated by surges of fecal contamination when Mexican pipes break, pumps fail and rain falls.
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 River.
A plan to pipe treated wastewater from Tijuana to the Guadalupe Valley is being championed by authorities who say the project not only would support the state’s wine-growing region, but also solve another problem: reducing the flow to the overburdened San Antonio de los Buenos coastal sewage treatment plant.
Mexico is pledging to spend $4.3 million to clean the Tijuana river channel after two California cities sued a U.S. agency over the decades-old problem of sewage fouling U.S. wetlands and beaches.
It’s a blustery day in the border town of Mexicali in Baja California, Mexico, and five men are huddled inside a makeshift encampment covered with protest signs outside the city’s government offices.
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 contaminants from Tijuana to San Diego.
Beaches as far north as the Hotel del Coronado have been closed following weekend showers that flushed sewage-polluted water through the Tijuana River and into the Pacific Ocean.
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 international border before reaching the ocean on the U.S. side, is said to be one of the most polluted waterways in the world.
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 protect citizens on both sides of the border from what he calls 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 Friday in the most dramatic attempt in decades to force the federal government to plug up the millions of gallons of sewage and polluted water that routinely stream over the border from Tijuana into the San Diego region.
Monarch butterflies migrate from the U.S. and Canada to Mexican pine and fir forests that thrive at about the same altitude as prime avocado-growing land. Previously, deforestation linked to lucrative avocado planting had been seen in areas to the west and south of the reserve.
Mexico City got a substantial warning before the shaking from a distant earthquake arrived Friday — some 30 to 60 seconds broadcast over loudspeakers from an earthquake early warning system. It was another success for Mexico City’s earthquake warning system — one which California, Oregon and Washington state still lack, and one that is an ongoing target for elimination by President Trump.
Lake Powell, which straddles Utah and Arizona, is expected to get 47 percent of its average inflow because of scant snow in the mountains that feed the Colorado River, said Greg Smith, a hydrologist with the Colorado Basin River Forecast Center, part of the National Oceanic and Atmospheric Administration.
Constellation Brands, maker of Modelo and Corona beers, finds itself in the crossfire of a bitter dispute. On one side are government officials who are vowing to see the project through; on the other, opponents determined to shut it down, saying the plant will use a large amount of water that should go to local farmers.
Sen. Dianne Feinstein (D-Calif.) called on the Trump administration Wednesday to help plug Tijuana’s rampant spills of sewage and other polluted water, which routinely foul beaches in San Diego and cause border patrol agents to fall ill.
Drought and climate change are having a noticeable impact on the Colorado River Basin, and that is posing potential challenges to those in the Southwestern United States and Mexico who rely on the river. In the just-released Winter 2017-18 edition of River Report, writer Gary Pitzer examines what scientists project will be the impact of climate change on the Colorado River Basin, and how water managers are preparing for a future of increasing scarcity.
States, federal and Mexican officials hailed a binational agreement this fall that they said could lead to a radical shift in how the region prepares for and responds to drought. But three months later, they appear no closer to a drought contingency plan, as negotiations have pitted states and water districts against one another, as the U.S. tries to hammer out details of the plan.

The Colorado River and its tributaries provide water for about 40 million people and farmlands from Wyoming to Mexico. … In the Mexicali Valley, farmers say they’re concerned that as the pressures on the river grow – and as the [United States-based Constellation Brands'] brewery drinks up more of that precious supply – they’re likely to get less water.
With Tijuana and other rapidly growing coastal cities heavily dependent on the Colorado River, Baja California urgently needs to find new water sources. Baja California Gov. Francisco Vega de Lamadrid’s administration has offered a solution: Build the largest desalination plant in the Western Hemisphere, enough to ensure a supply for decades to come.
San Diego County authorities have lifted a closure of the Imperial Beach shoreline that was impacted by sewage-contaminated flows from the Tijuana River entering the United States.
Precipitation carrying tainted water through the Tijuana River into the Pacific Ocean triggered beach closures Tuesday evening from the international border to Seacoast Drive in Imperial Beach. … The pollution from stormwater runoff adds to spills from aging pipes and potentially hazardous discharges from the deteriorating San Antonio de Los Buenos sewage treatment plant in Punta Bandera, located about six miles south of the border.
The U.S. Section of the International Boundary and Water Commission announced Thursday that it wants to hold a workshop with San Diego-area cities and agencies in hopes of staving off a lawsuit over the flow of sewage from Mexico.
Officials in Imperial Beach said Wednesday that sewage flowing up the coast from Tijuana fouled miles of shoreline over the weekend, severely sickening surfers and other beach goers. Mayor Serge Dedina, who also fell ill, said he received no advanced notice from officials in Mexico about the pollution.
The San Diego County Board of Supervisors voted Tuesday to join the growing legal campaign to force the federal government to do more to stop sewage from spilling over the border from Tijuana that routinely fouls South Bay beaches. “Enough is enough,” Supervisor Greg Cox, whose district includes border region with Mexico, said in a statement.
The effort to prevent sewage from flowing from Tijuana into San Diego County got a small boost Monday when Gov. Jerry Brown signed legislation to provide about $2.1 million in funds for the effort.
A newly signed pact between Mexico and the United States is believed to be the first time that two nations have agreed to allocate part of a shared water resource to the environment. Farmers and cities in both countries will reap benefits from Minute 323, an update to an existing agreement that seeks to sustainably manage the water of the overburdened Colorado River basin.
In March 2014, the staged release of water into the Colorado River Delta was an international spectacle. … Now, a second round of releases is headed to the delta that won’t be nearly as dramatic. But these flows will restore more riverfront with cottonwoods and willows than the last time and their impacts will likely last longer.
Imperial Beach, Chula Vista and the Port of San Diego took the first step toward suing the federal government to stop wastewater and raw sewage from continually pouring over the border from Tijuana into San Diego County. … On Thursday, Lt. Gov. Gavin Newsom, as the chair of the State Lands Commission, announced his support for the efforts by local officials in San Diego to address the situation.
The United States and Mexico expanded a long-term agreement Wednesday that will allow both nations to continue using the Colorado River while also pushing more conservation efforts to ensure that water is available during droughts.
The United States and Mexico unveiled an agreement Wednesday to preserve the overtaxed Colorado River, including spending millions of dollars on conservation and environmental projects and drawing up plans to deal with any shortages amid drought and climate change.
The United States and Mexico have agreed to renew and expand a far-reaching conservation agreement that governs how they manage the overused Colorado River, which supplies water to millions of people and to farms in both nations, U.S. water district officials said.
An agreement amending the longstanding treaty between the U.S. and Mexico on management of the Colorado River will continue the practice of water shortage sharing, but also fund new conservation and environmental programs, and aim to reduce the risk of ruinous drought.
“The network”, as I [John Fleck] call the Colorado River governance structure in my book, is gathering this week in Santa Fe, New Mexico, to among other things celebrate the signing of a new agreement extending the agreement between the United States and Mexico over water sharing and allocation on the Colorado River.
California’s lawsuit claims the federal government violated the U.S. Constitution’s separation-of-powers doctrine “by vesting in the Executive Branch the power to waive state and local laws.” The lawsuit also says the Department of Homeland Security decided to build the walls without complying with the Clean Water Act, the National Environmental Policy Act and the Coastal Zone Management Act.
The U.S. and Mexican governments are close to signing a landmark Colorado River deal that will establish rules for sharing water over the next decade and lay out cooperative efforts intended to head off severe shortages. … The new accord – titled Minute No. 323 to the 1944 Mexican Water Treaty – outlines a series of measures that build on the countries’ current 5-year agreement, which expires at the end of this year.
Federal water-quality officials on Thursday released a list of actions taken in recent years to stop wastewater from flowing from Mexico into the San Diego region, a little more than a week after the city of Imperial Beach threatened a lawsuit.
With Baja California pushing forward on its plan for a massive desalination plant in Rosarito Beach, a ground-breaking proposal to pipe some of that water to the United States has overcome a key hurdle. The U.S. State Department’s approval of a presidential permit marks a step forward for the Otay Water District and its vision for a cross-border pipeline to import the desalinated water from Mexico.
A much-anticipated report on a sewage spill in Tijuana that has sparked tensions with San Diego County gave mixed findings Monday. … The investigation was launched by the International Boundary and Water Commission, which oversees water treaties between Mexico and the United States, among other things.
The Colorado River Delta once spanned nearly 2 million acres and stretched from the northern tip of the Gulf of California in Mexico to Southern California’s Salton Sea. Today it’s one-tenth that size, yet still an important estuary, wildlife habitat and farming region even though Colorado River flows rarely reach the sea.
Baja California’s governor is preparing to declare a state of emergency in the coming days, hoping to draw financial aid for Tijuana’s strained and underfunded sewage system following a massive spill that sent millions of gallons of untreated wastewater from Tijuana across the border and into San Diego last month.
Standing next to the [Tijuana] river valley for a news conference Monday, Rep. Scott Peters said the U.S. Environmental Protection Agency now suspects that discharges may have totaled 230 million gallons, up from an initial figure of 143 million gallons.
Federal officials in the United States and Mexico announced on Thursday a joint investigation into a sewage spill in the Tijuana River that has polluted South County beaches as far north as Coronado — and which now looks to have been intentional as some elected leaders in San Diego suspected.
About 143 million gallons of sewage spilled into the Tijuana River during a period of more than two weeks, said a report released Friday. No other sewage spill in the greater San Diego-Tijuana region has approached this magnitude in years, according to the environmental group Wildcoast.
This issue of Western Water examines the ongoing effort between the United States and Mexico to develop a new agreement to the 1944 Treaty that will continue the binational cooperation on constructing Colorado River infrastructure, storing water in Lake Mead and providing instream flows for the Colorado River Delta.
As vital as the Colorado River is to the United States and Mexico, so is the ongoing process by which the two countries develop unique agreements to better manage the river and balance future competing needs.
The prospect is challenging. The river is over allocated as urban areas and farmers seek to stretch every drop of their respective supplies. Since a historic treaty between the two countries was signed in 1944, the United States and Mexico have periodically added a series of arrangements to the treaty called minutes that aim to strengthen the binational ties while addressing important water supply, water quality and environmental concerns.
As plans move forward for a massive desalination plan in Rosarito Beach, a proposed pipeline to carry some of that water to San Diego County is undergoing scrutiny by the U.S. State Department.
As birds sing and lizards scuttle in the lush vegetation of the Tijuana River Valley, helicopters circle overhead, and Border Patrol agents on all-terrain vehicles comb the area looking to stop illegal border-crossers.
The United States and Mexico are preparing to sign an agreement to address issues of sediment, trash and polluted stormwater that for years have plagued the Tijuana River watershed.
California’s little-known New River has been called one of North America’s most polluted. A closer look reveals the New River is full of ironic twists: its pollution has long defied cleanup, yet even in its degraded condition, the river is important to the border economies of Mexicali and the Imperial Valley and a lifeline that helps sustain the fragile Salton Sea ecosystem. Now, after decades of inertia on its pollution problems, the New River has emerged as an important test of binational cooperation on border water issues. These issues were profiled in the 2004 PBS documentary Two Sides of a River.
Redesigned in 2017, this beautiful map depicts the seven Western states that share the Colorado River with Mexico. The Colorado River supplies water to nearly 40 million people in Arizona, California, Colorado, Nevada, New Mexico, Utah, Wyoming and the country of Mexico. Text on this beautiful, 24×36-inch map, which is suitable for framing, explains the river’s apportionment, history and the need to adapt its management for urban growth and expected climate change impacts.
The Colorado River provides water to more than 35 million people and 4 million acres of farmland in a region encompassing some 246,000 square miles in the southwestern United States. 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.
As part of the historic Colorado River Delta, the Salton Sea regularly filled and dried for thousands of years due to its elevation of 232 feet below sea level.
The most recent version of the Salton Sea was formed in 1905 when the Colorado River broke through a series of dikes and flooded the seabed for two years, creating California’s largest inland body of water. The Salton Sea, which is saltier than the Pacific Ocean, includes 130 miles of shoreline and is larger than Lake Tahoe.
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 between the town of Los Algodones in northwestern Mexico and Yuma County, Ariz.
The Mexican Delta is located at the natural terminus of the Colorado River at the Gulf of Mexico, just south of the U.S.-Mexico border. The desert ecosystem was formed by silt flushed downstream from the Colorado and fresh and brackish water mixing at the Gulf.
The Mexican Delta once covered 9,650 square miles but has shrunk to less than 1 percent of its original size due to man-made water diversions.
This printed issue of Western Water examines how the various stakeholders have begun working together to meet the planning challenges for the Colorado River Basin, including agreements with Mexico, increased use of conservation and water marketing, and the goal of accomplishing binational environmental restoration and water-sharing programs.
This printed issue of Western Water examines the Colorado River Basin Water Supply and Demand Study and what its finding might mean for the future of the lifeblood of the Southwest.
This printed issue of Western Water explores some of the major challenges facing Colorado River stakeholders: preparing for climate change, forging U.S.-Mexico water supply solutions and dealing with continued growth in the basins states. Much of the content for this issue of Western Water came from the in-depth panel discussions at the September 2009 Colorado River Symposium.
This printed copy of Western Water examines the Colorado River Delta, its ecological significance and the lengths to which international, state and local efforts are targeted and achieving environmental restoration while recognizing the needs of the entire river’s many users.
