Water Board Waives Delta Rules That Protect Salmon

California’s water board decided Tuesday to temporarily allow more storage in Central Valley reservoirs, waiving state rules that require water to be released to protect salmon and other endangered fish.

The waiver means more water can be sent to the cities and growers that receive supplies from the San Joaquin-Sacramento Delta through the State Water Project and the federal Central Valley Project. The state aqueduct delivers water to 27 million people, mostly in Southern California, and 750,000 acres of farmland, while the Central Valley Project mostly serves farms.

Will California’s Excess Snow Become Usable Water This Year?

After three of the driest years in California history, this winter’s storms brought some of the wettest and snowiest weeks on record to parts of the state. Snowpack accumulated during winter is vital to the state’s water system because the natural form of water storage melts during the spring and fills reservoirs that can then distribute water downstream where needed.

DWR, Reclamation Submit Request to Adjust Water Right Permit Conditions to Conserve Storage

Following the driest three-year period on record, California experienced one of the wettest three weeks in January. But now those extreme wet conditions have activated a water quality standard in the Delta that, coupled with the extended dry period since then, could result in a sharp reduction in the amount of water that can be retained or moved into storage for both the State Water Project and federal Central Valley Project.

The Department of Water Resources and the U.S. Bureau of Reclamation are working in real time to operate the state’s water system to maximize water supply while protecting species and the environment. However, California continues to experience unprecedented swings in weather impacting water management operations.

Dramatic Photos Show Lake Oroville’s Rise After Epic Storms

Lake Oroville, a key component of California’s water supply, looks noticeably fuller after a series of January storms.

The atmospheric rivers dumped trillions of gallons of moisture on the state, spurring widespread flooding and destruction but also providing a healthy boost to snowpack and drought-sapped reservoirs.

Big Cities Are Downsizing Their Water Footprints

Forty percent or more of all water use in western US cities goes to outdoor watering of lawns, gardens, pools, and golf courses. One of the most effective urban water conservation strategies is to reduce the area of irrigated landscaping, or switching to less water-intensive vegetation.

My research group spent three years collecting water data and other information from 28 water utilities that serve a total of 23 million people in the American Southwest. The task wasn’t easy: 39 researchers were involved in collecting data from 45 different utility employees. Each of these utilities we surveyed is dependent on the Colorado River for some portion or all of their water supplies.

Water Transfer Facilitates Sweetwater Reservoir Refill

In November 2022 the Sweetwater Authority initiated a controlled transfer of water between the Loveland Reservoir to the Sweetwater Reservoir where water is treated and distributed to Authority customers in National City, Chula Vista and Bonita. The Loveland Reservoir, owned and operated by the water utility, was built in 1945 pooling water from the Sweetwater River. It has been a destination for fishing, birdwatching, and hiking. After a second water transfer in January between the two reservoirs and substantial storms which caused damage to the HUD-funded fishing pier and erosion damage to the trails, Loveland is now closed to the public for all recreational usage for an indefinite period of time.

Sweetwater Authority General Manager Carlos Quintero said, bottom line, with both water transfers there is not enough water to fish. He said Loveland has always been a water supply reservoir.

“Our mission is to provide water to the Sweetwater customers,” he said. “We use both of our reservoirs. They work in conjunction. Sweetwater is in Spring Valley and that is where we have our treatment plant. When conditions are optimal, when we are outside the arroyo toad breeding season, that is when we can transfer water from one reservoir to another. It is a 17-mile trek for every drop of water, and we try to find the optimal conditions to minimize our losses.”

Water Authority Helps Low-Income Customers With Water-Saving Devices

The San Diego County Water Authority has secured $3 million in grant funds to install water-saving devices  — water-efficient toilets and smart irrigation controllers — in underrepresented communities across the region, bolstering the agency’s long-running efforts to enhance water affordability.

The Water Authority will use the money to install 7,300 high-efficiency toilets and smart irrigation controllers covering about 4,000 locations, saving more than 6,000 acre-feet of water and helping enhance water efficiency and affordability for vulnerable customers. The funds are from the California Department of Water Resources’ Urban Community Drought Relief Grant program, designed to advance Governor Gavin Newsom’s strategy to adapt California’s water supply for a hotter and drier future.

Safe, reliable, affordable water

“This is another big step toward our goal of ensuring that everyone in San Diego County has access to safe, reliable and affordable water,” said Water Authority Board Chair Mel Katz. “Helping customers improve water efficiency ultimately saves them money and protects our most precious natural resource.”

In 2022, the Water Authority secured $25 million to cover overdue residential water bills resulting from the economic impacts of COVID-19. The Water Authority also operates an industry-leading asset management program designed to avoid the extreme costs of emergency repairs on large-scale water lines. And, the agency is advocating in Washington, D.C., for federal funds to defray the cost of generational upgrades to local dams and reservoirs.

Water-saving devices

The Water Authority’s Water-Use-Efficiency Direct Installation Program is designed to save residents money on water costs. To be eligible for the direct-install program, residents in manufactured housing communities, multifamily and single-family homes must be a customer within the Water Authority service area.

Reduce water use by 60%

The direct-install program conserves water by replacing inefficient toilets with high-efficiency models through professional installation at no cost to participants. According to the U.S. EPA, the replacement of older toilets with high-efficiency models can reduce water use by up to 60%.  The initiative also includes installing smart irrigation controllers at no cost and providing education on outdoor water-use efficiency. Smart irrigation controllers can make irrigation schedule adjustments more convenient and water-efficient by using local weather data and landscape conditions to tailor the amount, frequency, and timing of landscape watering.

The grant funds will extend the life of the Water Authority’s existing program that has installed 2,213 water-efficient toilets over the past 12 months. The program is funded and implemented through a partnership between the Water Authority, the Metropolitan Water District of Southern California and San Diego Gas and Electric.

Deadline for Colorado River Water Cuts Passes With No Agreement

The decades-old agreements that outline water rights to the Colorado River Basin are leading to an impasse on an issue affecting millions of people in the American Southwest.

On Jan. 31, the seven states that draw water from the basin had to come up with a plan to voluntarily cut back on using water from the basin. Six states — Arizona, Colorado, Nevada, New Mexico, Utah and Wyoming — agreed on one proposal. But California, which is the state the uses the most water, rejected that plan and submitted its own.

Resistance is Futile – Agriculture is Key to Fixing Lower Colorado River Water Shortages

The lower Colorado River has been out of balance for about 40 years, using more water than has been available.  As their reservoirs empty, the three lower basin states, federal government, and water users are getting around to addressing this problem.

California Water Agencies Submit Colorado River Modeling Framework to Bureau of Reclamation

California water agencies that rely on the Colorado River today 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.
