The federal government on Tuesday laid out two options for preventing the Colorado River’s depleted reservoirs from falling to critically low levels, saying it could either impose cuts across the Southwest by following the water-rights priority system or by using an across-the-board percentage.
The San Diego County Water Authority supports a consensus-based approach for long-term solutions to water supply issues in the Colorado River Basin. The U.S. Bureau of Reclamation on April 11 released a draft environmental document that considers changes to near-term operations on the Colorado River, including potential reductions in water supplies for California and across the Lower Colorado River Basin.
Reclamation’s draft Supplemental Environmental Impact Statement (SEIS) analyzes two alternatives, plus a no-action alternative, to protect critical elevations at Lakes Mead and Powell, the two reservoirs California depends on for its river supplies. Both reservoirs have declined due to unprecedented low levels from more than two decades of drought.
The release of the draft SEIS, which would modify the set of operating guidelines that manage river operations through 2026, comes even as heavy snows this winter signal some relief on the river.
“While this winter’s storms delivered an incredible snowpack, the release of the draft SEIS highlights that we need to continue to work with all Basin states, the tribes and Mexico toward a consensus-based approach that provides real and lasting solutions for all water users,” said Dan Denham, deputy general manager for the San Diego County Water Authority.

The first of the two action alternatives in the draft SEIS acknowledges the priority system for water rights under existing agreements and laws. The San Diego region’s river supplies are largely protected from reductions because they are tied to California’s senior rights within the Lower Colorado River Basin as well as the Imperial Irrigation District’s (IID) high priority rights through the Water Authority’s conserved water transfer agreement with IID.
The second alternative calls for Reclamation to analyze the effects of reductions “distributed in the same percentage” for all water users in the Lower Basin states – California, Arizona and Nevada – despite there being no precedent or foundation for this approach under existing laws. It would mean across-the-board reductions for all water users in the region, including those with senior water rights.
Reclamation has stated it is expecting input from states, tribes and water agencies to fine-tune and adjust these alternatives. Discussions are ongoing between stakeholders.

“The Water Authority will continue to work in collaboration with our partners on the Colorado River Board of California to ensure California’s high priority water rights on the river are upheld through this SEIS process while we also work with all river stakeholders to develop long-term, durable solutions for the river,” Denham said.
The draft SEIS will be available for public comment for 45 calendar days and the final SEIS is anticipated to be available with a Record of Decision in Summer 2023, according to the Bureau of Reclamation. Comments on the draft SEIS are due May 30. This document will inform the August 2023 decisions that will affect 2024 operations for Glen Canyon and Hoover Dams.
The proposal to address immediate water supply challenges complements Reclamation’s ongoing process to develop new guidelines for Colorado River Operations when the current interim guidelines expire at the end of 2026.
The San Diego County Water Authority will host water leaders from throughout Southern California March 15 for the monthly meeting of the Colorado River Board of California. On Tuesday, March 14, before the formal meeting, CRB board members will tour projects in the region that promote water resiliency.
The CRB will consider the complex water supply issues facing the Southwest U.S. during its meeting. San Diego Congressman Scott Peters is also scheduled to address the CRB.

The tour is part of a new program implemented by CRB, under the leadership of Chair JB Hamby, Imperial Irrigation District’s representative, and Vice Chair Jim Madaffer, the Water Authority’s representative and Water Authority board member, to build greater awareness of each CRB member agency’s efforts to serve their region and manage their river supplies.
“The Colorado River Board is so important to ensuring California’s voice is heard on the river, especially during these difficult times as we work to find collaborative solutions to the river’s challenges now and into the future,” Madaffer said. “We look forward to showcasing the local supply projects, online now and planned, that create water resiliency locally, but that also reduce the demand on the river.”

Established in 1937, the CRB is a state agency tasked with protecting the interests and rights of the state and its agencies in water and power resources from the Colorado River.
The Water Authority is a member of the CRB along with IID, the Metropolitan Water District of Southern California, the Coachella Valley Water District, the Palo Verde Irrigation District, the Los Angeles Department of Water and Power, the California Department of Water Resources, and the California Department of Fish and Wildlife. CRB representatives, including two additional members from the public, are appointed by the Governor.

The CRB represents California in discussions and negotiations with the Basin states, the U.S. Bureau of Reclamation, governmental agencies at all levels, tribes, and Mexico regarding the management of the river.
CRB members on the tour will see two local water supply projects generating water now – the Claude “Bud” Lewis Carlsbad Desalination Plant – and planned – the East County Advanced Water Purification Plant.
The seawater desalination plant, the largest in the nation, came online in 2015 and recently passed the milestone of producing more than one-billion gallons of water for the San Diego region.

“The desalination plant is not only important to our region, but the Water Authority believes the plant could be part of an overall long-term solution to support Lake Mead, California’s critical river reservoir, under a proposal we are considering to expand the plant,” said Madaffer.
Now under construction, the East County Advanced Water Purification facility, or East County AWP, is a collaborative partnership between two Water Authority member agencies, the Padre Dam Municipal Water District and the Helix Water District, and the County of San Diego and City of El Cajon.
The plant is projected to generate a local, reliable and drought-proof drinking water supply utilizing state-of-the-art technology to recycle and reuse the region’s wastewater. The East County AWP is expected to produce 30% of East San Diego County’s water supply by early 2026, and is one of the innovative water purification facilities in the county either in operation or in development.
Scheduled to be operating in 2026, the East County AWP is projected to generate up to 11.5 million gallons per day of purified water— meeting approximately 30% of current drinking water demands for East San Diego County residents and businesses. Photo: San Diego County Water Authority
Following the facility tours on March 14, the CRB will hold its monthly meeting March 15 at the Water Authority’s Kearny Mesa headquarters in San Diego. The meeting is scheduled to start at 10 a.m. and is open to the public.

(Editor’s note: The Helix Water District and Padre Dam Municipal Water District, are two of the San Diego County Water Authority’s 24 member agencies that deliver water across the San Diego County region.)
California water agencies that rely on the Colorado River on January 31, proposed a modeling framework for the U.S. Bureau of Reclamation to evaluate as it considers actions to help stabilize reservoir elevations and protect critical infrastructure to ensure the Colorado River system can continue to support 40 million people, nearly 6 million acres of agriculture, and Tribes across seven states and portions of Mexico.
The modeling framework outlines a constructive approach to achieve additional water use reductions while protecting infrastructure, prioritizing public health and safety, and upholding the existing body of laws, compacts, decrees, and agreements that govern Colorado River operations (known collectively as the Law of the River). The approach builds on the California agencies’ commitments announced last fall to voluntarily conserve an additional 400,000 acre-feet of water each year through 2026 to protect storage in Lake Mead and help stabilize the Colorado River reservoir system.
California’s proposed framework seeks to protect Lake Mead elevation of 1,000 feet and Lake Powell elevation of 3,500 feet by modifying some parameters governing reservoir operations, maximizing the impact of existing plans and voluntary conservation actions, and increasing cutbacks if Lake Mead elevations decline. It also protects baseline water needs of communities across the West by prioritizing water supplies for human health and safety. The proposal was carefully developed to enable workable phased water use reductions and ensures protection of adequate water volumes in Lake Mead and Lake Powell.
“The alternative provides a realistic and implementable framework to address reduced inflows and declining reservoir elevations by building on voluntary agreements and past collaborative efforts in order to minimize implementation delays. California’s alternative protects critical elevations and uses adaptive management to protect critical reservoir elevations through the interim period,” JB Hamby, chair of Colorado River Board of California and California’s Colorado River Commissioner, wrote in a transmittal letter to Reclamation.
The approach differs from a modeling proposal submitted to Reclamation on January 30 by the six other basin states. The six-state proposal would direct the majority of water use reductions needed in the Lower Basin to California water users through a new apportionment method based on “system and evaporative losses.” The proposal directly conflicts with the existing Law of the River and the current water rights system and mandates cutback without providing tools to manage reductions.
In October 2003, the San Diego County Water Authority, Coachella Valley Water District, Imperial Irrigation District, Metropolitan Water District of Southern California, State of California and U.S. Department of the Interior completed a historic set of agreements to conserve and transfer Colorado River water.
For the past several months, California water users have sought a timely, practical and implementable solution with other Lower Basin users that can be implemented over the next three years to protect critical elevations in Lake Mead while longer-term changes are negotiated to update 2007 Interim Guidelines that will expire at the end of 2026. Suggestions to fundamentally change the Law of River are appropriately addressed through this shared process to update the guidelines.
California’s water agencies remain committed to working with all Colorado River basin states to take urgent, fair, and achievable action now to avoid unacceptable risks to communities, farms and economies in California and the rest of the basin.
For decades, California has been a leader in managing its Colorado River water resources and collaborating in basin-wide efforts to more effectively operate and manage the reservoir system and to incentivize water conservation as demands have increased in the face of shrinking supplies due to climate change.
In 2003, California permanently reduced its use of Colorado River water from about 5.2 million acre-feet annually to its basic apportionment of 4.4 million acre-feet, a permanent annual reduction in water use of about 800,000 acre-feet. The reduction in use resulted from implementing a combination of agricultural and urban conservation activities.
Since 2003, water users in California have taken significant actions to conserve Colorado River water, adding over 1.5 million acre-feet and 20 feet of elevation of conserved water to Lake Mead since 2007. California water users committed to further conservation to bolster storage in Lake Mead through the 2019 Drought Contingency Plan. California has invested billions of dollars in urban and agricultural conservation across Southern California, through programs that reach virtually every Colorado River water user in the state.

“Twenty years ago, California adopted the largest water conservation-and-transfer agreement in U.S. history that not only supports the bulk of our nation’s food system but also sustains the environment. This multi-billion-dollar conservation-focused framework – the Quantification Settlement Agreement – is the blueprint for other states to follow. California has done its part and is willing to do more, but it’s time for the other states to step up and create their own conservation programs that sustain the quality of life in their communities,” said Jim Madaffer, vice chair of the Colorado River Board of California, representing the San Diego County Water Authority.
“For over 20 years, Metropolitan has met the challenge of reducing our use of Colorado River water, and we are committed to doing more now. But we must do it in a way that does not harm half of the people who rely on the river – the 19 million people of Southern California. We must do it in a way that does not devastate our $1.6 trillion economy, an economic engine for the entire United States. We must do it in a way that can be quickly implemented, adding water to lakes Mead and Powell without getting mired in lengthy legal battles. We must do it in a way that maintains and strengthens partnerships on the river, allowing us to work together to build longer term solutions. The proposal presented today by California does all of this by equitably sharing the risk among Basin states without adversely affecting any one agency or state. The plan presented yesterday, which shut out California, does not. California knows how to permanently reduce use of the river – we have done it over the past 20 years, through billions of dollars in investments and hard-earned partnerships. We can help the entire Southwest do it again as we move forward,” said Adel Hagekhalil, general manager, Metropolitan Water District of Southern California.
“The Colorado River – Imperial Valley’s only source of water – supports far more than our rural disadvantaged community as it provides for a robust agricultural industry that feeds millions of people and provides food security for this nation. California, and particularly the Imperial Irrigation District, is working to be part of the solution, however we also believe in upholding the Law of the River and not shouldering the burden of supply limitations for states and agencies that have outgrown their water rights. California has spent the past two decades successfully working together to resolve intra-state supply and demand imbalances to sustain the Colorado River. Since the signing of the Quantification Settlement Agreement, the largest ag-to-urban water conservation and transfer agreement in U.S. history, IID’s water management programs have generated over 7.2 million acre-feet in support of the Colorado River system. Today, IID and its California partners have proposed a balanced and implementable plan that begins to address the monumental challenges we face with the ongoing Colorado River drought,” said Henry Martinez, general manager, Imperial Irrigation District.
“Historically, CVWD and our agricultural community have invested heavily in its irrigation delivery system to minimize water loss, including canal lining projects, a closed pipe irrigation distribution system and installing drip irrigation. We have prioritized the efficient use of Colorado River water over the long term. We also took action last year with other California agencies to voluntarily identify a collection of Colorado River water conservation and reduction actions to save 400,000 acre-feet annually through 2026. We support our California partners and are committed to reaching a 7-basin state consensus on a framework for additional water use reductions through 2026,” said Jim Barrett, general manager, Coachella Valley Water District.
“One-hundred and forty-six years ago, the original developers of our Palo Verde Valley filed and were granted the very first water rights to Colorado River water. Secured by those rights, farmers and farm workers have invested multiple generations of farm loans and hard work to produce food and fiber for consumers. Surrounding our agriculture are small rural cities that depend exclusively upon Colorado River water for their domestic supply. Farmers and landowners in Palo Verde Irrigation District want to be part of a solution to the current mismatch of supply and demand on the River in a manner that honors existing Public Law, and Administrative Law,” said Bart Fisher, president, Palo Verde Irrigation District Board of Trustees.
“The Colorado River has been the lifeblood of the Quechan people since time immemorial, and we have a deep and abiding responsibility to be good stewards of the River – for the Tribe and its members, for the species and ecosystems that it sustains, and for the benefit of our fellow tribes and non-Indian neighbors throughout the Basin. It is why we have always fought for and will continue to defend our water. The modeling proposal submitted by the State of California to the Bureau of Reclamation for inclusion as part of its development of the SEIS reflects a meaningful effort to address the hydrologic challenges facing the Basin while respecting the senior water rights of the Tribe and others and ensuring that the Colorado can continue to exist as a living river,” said Quechan Tribal Council President Jordan Joaquin.
No state reliant on the Colorado River will be immune to water usage cuts as climate change worsens the drought. It’s critical that an agreement has support from all seven states impacted to protect the long-term sustainability of our region.

Established in 1937, CRB consists of agency representatives from the Water Authority, IID, Metropolitan Water District of Southern California, Coachella Valley Water District, Palo Verde Irrigation District, and the Los Angeles Department of Water and Power. Additional representatives include the directors of the California Department of Water Resources and Department of Fish and Wildlife, along with two public representatives.
Seven counties in Southern California receive water and hydroelectric energy from the Colorado River. Colorado River water is used for drinking water by over 19 million people in Southern California and irrigates over 600,000 acres of agricultural lands that produce fruits, vegetables,and other crops that help feed our nation’s families.
(Editor’s Note: Jim Madaffer has been the San Diego County Water Authority’s CRB representative since 2019, and is serving a four-year term as vice chair following his election on January 11 during the CRB meeting in Ontario, Calif. He joined the Water Authority Board in November 2012 representing the City of San Diego and served a term as Board Chair.)
Predicting the amount of water the Colorado River can provide in a given year has always been a challenge. The river’s flow is famously erratic, dictated by the size of the often-fickle Rocky Mountain snowpack and other variables such as soil moisture and changes in temperature. The old expectations of the Compact signers is giving way to a new reality on the river. Over the last century, the river’s flows in the Upper Basin have dropped by 20%. Scientists have pinned warming temperatures as the main cause of the disappearing flows and predict the trend will worsen as the Upper Basin, source of most of the river’s water, becomes even hotter and drier.
San Diego County Water Authority Board Member Jim Madaffer has been elected vice chair of the Colorado River Board of California. The CRB represents California in river management discussions with other Basin states, federal agencies, tribes, and Mexico.
Madaffer, the Water Authority’s CRB representative since 2019, will serve a four-year term as vice chair following his election on January 11 during the CRB meeting in Ontario, Calif. He will serve alongside Imperial Irrigation District Board Vice President JB Hamby, who was elected chair.

CRB’s role has been pivotal in protecting the state’s share of the river during this period when two decades of drought have caused a sharp supply/demand imbalance, leading to a severe decline in water levels in the river’s two main reservoirs, Lake Mead and Lake Powell.
Led by CRB, California has proposed conserving up to 400,000 acre-feet annually through 2026 to support the river. Though that conservation will not affect the San Diego region’s high-priority Quantification Settlement Agreement supplies, the region is continuing to take active steps to conserve as it has over the past three decades.
“The San Diego region is committed to doing our part to be good stewards of our water supplies,” said Water Authority Board Chair Mel Katz. “We also believe in working collaboratively with all stakeholders on the river, and Jim’s leadership on the Colorado River Board in his new role as vice chair will only advance those efforts.”
