A CWA board vote Thursday, Feb. 22, approved the recommendation of the CWA’s Finance Planning Workgroup. The calendar year 2025 changes include apportioning 40% of the transportation charge as a Transportation Fixed Rate allocated to member agencies by a seven-year rolling average with the current volume-based Transportation Rate designed to recover the remaining 60% of the forecasted annual revenue requirement.
In the wake of the arrival of a history-making year in weather, the San Diego County Water Authority is working with two other agencies and the federal government to implement lasting changes to regional water management.
San Diego County and Southern California water industry leaders commemorated the 20th anniversary of the 2003 Quantification Settlement Agreement (QSA), cited as a model of collaboration, relationship building, and voluntary conservation efforts among Southern California’s water agencies.
The QSA is a historic set of water agreements enabling California to live within its Colorado River apportionment, helping provide reliable water supplies for all users. Speakers at the commemoration event highlighted how the QSA continues to meet its goals while protecting agriculture and addressing the environment.

San Diego County Water Authority (Water Authority) Board Chair Mel Katz described the positive change in water management ushered in by the QSA as “a set of more than two dozen agreements that represent the dawn of a new era in water management in San Diego County and the Southwest – an era of water efficiency and supply reliability despite climate extremes.” Katz recognized the conservation efforts of the Imperial Irrigation District (IID) and Imperial Valley farmers.

IID Board President Alex Cardenas reported Imperial County agriculture has conserved 7.5 million acre-feet over the 20 years of the agreement, while still enabling agriculture to succeed. The Valley’s agricultural economy has grown from $1.8 billion in 2003 to $2.6 billion in 2023. according to the latest crop reports.
Water Authority General Manager Dan Denham said the Water Authority, IID, Metropolitan Water District of Southern California (MWD), and the Coachella Valley Water District continue to work together to ensure flexibility in how the river is managed and the needs of each agency are met. “We are getting to a place where we can be creative and do things differently.”
MWD General Manager Adel Hagekhalil called the QSA a great success and a great lesson. “We all came together. It was tough, but it was important.”
California Natural Resources Agency Secretary Wade Crowfoot congratulated the QSA partners on their achievement via a video message, calling it a “game changer” that remains as important today as it was 20 years ago. U.S. Senator Alex Padilla also offered his congratulations via a video message, crediting the leadership of all partners for their efforts to sustain the QSA.

San Diego Assemblyman David Alvarez told those gathered it was important to celebrate what was accomplished through the QSA. “The significance to me of the QSA is the listening that occurred,” he said, noting that the QSA brought agencies together to listen to each other as partners to create a set of mutually beneficial agreements.
Colorado River Board of California Vice Chair and Water Authority board member Jim Madaffer said the QSA provides a model of flexible river management, calling it a lesson “that we are so much better when working together than separately.”
Looking toward the challenges ahead on the river, water industry leaders noted the QSA must be a part of critical water discussions as agencies seek collaborative solutions to ensure the Colorado River can continue to be a reliable water source well into the future.
Thanks to a decades-long supply diversification strategy and continued efficient use of water across the region, the San Diego County Water Authority announced that the region has reliable supplies to meet demands in Water Year 2024, which started October 1.
Hydrologists use Oct. 1 to begin measuring the snow and rain that will help carry water users through dry summer months the following calendar year. This fall, El Niño conditions continue to strengthen and could bring above-average precipitation to Southern California.

Hydrologists use Oct. 1 to begin measuring the snow and rain that will help carry water users through dry summer months the following calendar year. This fall, El Niño conditions continue to strengthen and could bring above-average precipitation to Southern California. In a recent El Niño forecast by NOAA, there is a greater than 95% chance that El Niño continues across the Northern Hemisphere through the winter into 2024. The chance of a “strong” El Niño is 71%.
“San Diego County continues to have the water necessary to support our $268 billion economy and quality of life for 3.3 million residents,” said Mel Katz, chair of the Water Authority Board of Directors. “We are grateful for the reprieve from drought – but we recognize that dry times will return, probably sooner than later. We are ready when they do.”
Despite significant rain and snow over the past 12 months, longer-term trends indicate a hotter, drier Southwest climate. Across the arid Southwest, water agencies are spending billions of dollars to increase water supply reliability as they balance the costs of investments against the costs of not having enough water for homes and businesses.
Since the early 1990s, the Water Authority and its 24 member agencies have made major investments in supply reliability, including in the landmark conservation-based 2003 Quantification Settlement Agreement, which provides over half of the region’s water, the building of the nation’s largest seawater desalination plant, and in the maintaining and upgrading of water infrastructure. That strategy has paid off during dry times. Just one year ago, the situation was dramatically different in other parts of Southern California, as millions of residents were reduced to health and safety water rations – though regional investments meant the San Diego region was spared.
Compared to recent years, the new water year begins with improved supply conditions at the Water Authority’s two imported water sources – the Colorado River and the Sierra Nevada. On the Colorado River, a good water year and conservation efforts raised storage levels, prompting the U.S. Bureau of Reclamation to declare that California will not face supply restrictions through 2024.
Meanwhile, in Northern California, Lake Oroville and San Luis Reservoir – two key State Water Project reservoirs – had 2.76 million more acre-feet in storage combined at the end of August 2023 compared to the prior August. (An acre-foot is approximately 325,900 gallons, or enough water to meet the annual needs of three typical single-family households.)

In the San Diego region, water users also benefit from the Claude “Bud” Lewis Carlsbad Desalination Plant, as well as increased water storage levels in many local reservoirs. At the end of August 2023, member agency local storage was up 137,400 acre-feet, or 80%, compared to the same time in 2022. Meanwhile, the Water Authority had approximately 100,000 acre-feet available in emergency and carryover storage. This represents emergency storage for up to six-months and carryover storage to minimize or avoid potential supply cutbacks during periods of drought or other supply shortage events.
This October marks 20 years since San Diego cut a famous deal that protected it from drought but paved the way for putting a high price on otherwise free water from the Colorado River.
The hard-fought deal – called the Quantification Settlement Agreement, or QSA – dramatically lowered how much water California takes each year from this river that makes life possible in seven western U.S. states and northern Mexico. It ensured, for the first time, that California wouldn’t use any more than its share. And it achieved that by putting a cap, for the first time, on how much water the farmers in Imperial Valley could take. Water officials would now meticulously count every gallon that once haphazardly emptied from farm fields into the Salton Sea. Today, that massive lake is in danger of becoming a massive public health and ecological disaster.
San Diego County water officials said Monday the region should have plenty of water in the coming year, even though there is lingering concern about water coming from the Colorado River basin.
The San Diego County Water Authority (SDCWA) said local customers are reaping the benefits from decades of effort to diversify and secure water supplies.
“Because we’ve invested. We’ve done the work — in our infrastructure, in our reliability and in conservation,” said Efren Lopez, a water resource manager with the SDCWA.
Water is the lifeblood of civilizations, and the management of this precious resource has always been a challenging task. The Imperial Irrigation District (IID) holds a significant stake in water rights, playing a vital role in water distribution and agriculture. This essay delves into the history, challenges, and strategies employed by IID to manage water rights responsibly and sustainably.
U.S. Bureau of Reclamation officials declared the first-ever water shortage on the Colorado River on Monday, Aug. 16, and the Imperial Irrigation District weighed in on Tuesday, Aug. 17.
That declaration has triggered cuts in water supplies to some Arizona farmers and areas of Nevada for 2022.
In the U.S., Arizona will be hit the hardest and lose 18 percent of its share from the Colorado River next year, according to the Associated Press.
That’s around 8 percent of the state’s total water use. Nevada will lose about 7 percent of its allocation, or 21,000 acre-feet of water.
California is spared from immediate cuts because it has more senior water rights than Arizona and Nevada. Mexico will see a reduction of roughly 5 percent, or 80,000 acre-feet.
The Imperial Irrigation District has addressed the cuts, though the district won’t yet be affected by the recently announced shortage reduction.
Tina Shields, the Water Department Manager of IID, speaks on the QSA, why it was implemented, and the contention between the state and IID as water was forced from agricultural communities to urban areas.
