Snow is forecast every day this week in the heart of the Colorado Rockies, and snowpack levels have climbed to nearly 150% as warmer spring temperatures near.
It could be the winter we remember as one of the bright spots in a drought that defined the past two decades in the Colorado River Basin.
After a relatively dry February, the spigot has turned back on over the North State, thanks to a series of late-winter storms in March that have brought water levels up at Lake Shasta to almost 40 feet from its crest.
The lake — the state’s largest reservoir — has risen 8 feet over the past week and more than 100 feet since Dec. 1, U.S. Bureau of Reclamation numbers show.
Tom Brundy, an alfalfa grower in California’s Imperial Valley, thinks farmers reliant on the shrinking Colorado River can do more to save water and use it more efficiently. That’s why he’s installed water sensors and monitors to prevent waste on nearly two-thirds of his 3,000 acres.
But one practice that’s off-limits for Brundy is fallowing — leaving fields unplanted to spare the water that would otherwise irrigate crops. It would save plenty of water, Brundy said, but threatens both farmers and rural communities economically.
There is an old saying in the water world that it is better to be upstream with a shovel than downstream with a law book, which is the position California finds itself in as it stands apart from its neighbors on the Colorado River in negotiations over the use of the river’s water.
On Jan. 31, representatives for the six other basin states submitted a proposal to the U.S. Bureau of Reclamation, describing the measures by which the supply deficit on the Colorado River should be closed in the near term.
California farms and cities that get their water from the Central Valley Project are due to receive a large increase in water allocations this year after snowpack and reservoirs were replenished in winter storms, the U.S. Bureau of Reclamation announced Wednesday.
Most recipients of the Central Valley Projects are irrigation districts that supply farms, and some are cities, including those served by the East Bay Municipal Utility District and Contra Costa Water District in the Bay Area.
Figures from the federal government show Nevada used 8% less water from the Colorado River in 2022 as conservation ramped up during one of the drought’s worst years.
Southern Nevada continues to make “tremendous progress” in water savings, according to John Entsminger, general manager of the Southern Nevada Water Authority.
The Colorado River, which allows the desert to sustain itself and powers millions of American homes, is currently engaged in the fight of its life. The rapidly sinking river—victim of a nearly 23-year-long megadrought—stretches 1,450 miles, snaking its way from Colorado through Arizona, Nevada, and California, and finally into Mexico, where it should theoretically dump out into the Sea of Cortez.
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.

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.
Because of these extreme weather swings, DWR and Reclamation are taking proactive measures to manage the state’s water supply to store and capture more water in preparation for a return to hot, dry weather in the next two months.
Both agencies submitted a Temporary Urgency Change Petition (TUCP) to the State Water Resources Control Board requesting approval to modify compliance with Delta water quality conditions specified in their water right permits, while proposing measures to avoid impacts on Delta smelt.
DWR and Reclamation typically would seek this kind of change during extremely dry conditions. But the swing to extremely wet conditions after extremely dry conditions has created challenges, and the projects are acting to enable additional opportunities for water storage north and south of the Delta while maintaining protections for species.
The request for the TUCP follows protective actions taken by DWR and Reclamation under state and federal endangered species permits in late December and early January, including the “first flush” action to reduce pumping and allow storm runoff to flow through the system for the benefit of native fish species. Recent monitoring information shows the actions worked as intended, with key fish species moving downstream of the Delta and away from the direct influence of the SWP and CVP pumps.
The water quality and water right permits that dictate SWP and CVP operations require certain water quality conditions to be met at specific compliance points in the Delta to provide for favorable conditions for endangered fish species. In consultation with the Department of Fish and Wildlife, DWR and Reclamation are requesting that the State Water Resources Control Board temporarily move the compliance point in the projects’ water rights permits from Port Chicago six miles east to Chipps Island. The alternative compliance point is anticipated to ensure water quality sufficient to protect beneficial uses.
If approved by the State Water Board, these actions would allow DWR and Reclamation to move and retain more stormwater and runoff in the state’s reservoirs in preparation for continued dry periods. A total of approximately 300,000 acre-feet would be saved for later use by the State Water Project alone.
While the January storms provided much-needed rain and snowfall, they did not end drought conditions for much of the state and California remains in a drought emergency. Regions that rely on the Colorado River system face increasingly severe water shortage conditions, and groundwater basins that serve communities in the Central Valley will not recover quickly from back-to-back years of drought and chronic overdraft.
DWR will continue to work with federal and state partners to be proactive and respond in real time to balance multiple water supply needs.
Dueling plans for how to save the fast-drying Colorado River have been submitted by California and six other states to federal authorities, who have made clear they may impose draconian cuts if consensus is not reached regionally on deep reductions. That agreement could be hard to come by.
California swung hard at six other Western states late Tuesday, submitting its own proposal for more than 3 million acre feet in reductions — both from current and future agreements — if necessary from the river’s dwindling reservoirs, Lake Powell and Lake Mead.
