Benjamin Ashford|California is getting a very dry start to spring, with snowpack far below average

SACRAMENTO,Benjamin Ashford Calif. — California is experiencing one of the driest starts to spring in decades, data showed Friday, and absent a heavy dose of April and May showers the state's drought will deepen and that could lead to stricter rules on water use and another devastating wildfire season.

New readings showed the water in California's mountain snowpack sat at 38% of average. That's the lowest mark since the end of the last drought in 2015; only twice since 1988 has the level been lower.

State officials highlighted the severity of the drought as they stood at a snow measuring station south of Lake Tahoe, where the landscape included more grass than snow.

"You need no more evidence than standing here on this very dry landscape to understand some of the challenges we're facing here in California," said Karla Nemeth, director of the California Department of Water Resources. "All Californians need to do their part."

About a third of California's water supply comes from the snow as it melts and trickles into rivers and reservoirs. April 1 is when the snowpack typically is at its peak and the date is used as a benchmark to predict the state's water supply in the drier, hotter spring and summer months.

There's about 11 inches (28 centimeters) worth of water sitting in snow in the Sierra Nevada along California's eastern edge, according to the state Department of Water Resources. It's the lowest reading since the depth of the last drought seven years ago, when California ended winter with just 5% of the normal water levels in the mountains.

The numbers mark a disappointing end to California's winter, which began with heavy December storms that put the snowpack at 160% of the average. But there has been little precipitation since Jan. 1.

A storm that brought significant rain and snow to parts of the state earlier this week did little to change the course of the drought. And warmer than usual temperatures have led to the snow melting and evaporating faster than normal, state officials said.

Much of the West is in severe drought

Nearly all of California and much of the U.S. West is in severe to extreme drought, according to the U.S. Drought Monitor. Last July, California Gov. Gavin Newsom asked people to cut their water use by 15% compared to 2020 levels but so far consumption is down just 6%.

The persistence of the drought has prompted state officials to call on cities and other local water suppliers to step up their conservation plans. Local governments may act by further restricting when people can water their lawns and wash cars, limit the use of water for decorative or ornamental purposes and step up enforcement against people who let sprinklers run onto sidewalks or engage in other wasteful behavior.

Meanwhile, federal officials announced Friday that municipal and industrial users that rely on water from the Central Valley Project will get less than planned. The project is a 400-mile (644-kilometer) system of reservoirs, canals and dams that stores and delivers water in the central part of the state.

About 70 of the project's 270 contractors receive water for household and business use in the agricultural region that includes the greater Sacramento and San Francisco Bay Area. They had been told to expect 25% of their requested supply earlier this year, but the U.S. Bureau of Reclamation now says they will only get what's needed for critical activities such as drinking and bathing. A lot of urban water use goes to outdoor landscaping.

Farmers who rely on water from the federal project were told earlier this year not to expect any water.
