The California Department of Water Resources first manual snow survey of the season Tuesday at Phillips Station recorded 55.5 inches of snow depth and a snow water equivalent of 17.5 inches, which is 177% of average for the location. The snow water equivalent measures the amount of water contained in the snowpack and is a key component of DWR’s water supply forecast. Statewide the snowpack is 174% of average for this date.

California is expected to see continued rain and snow over the next seven days, with the threat of flooding in parts of California. Conditions so far this season have proven to be strikingly similar to last year when California saw some early rainstorms and strong December snow totals only to have the driest January through March on record.
“The significant Sierra snowpack is good news but unfortunately these same storms are bringing flooding to parts of California,” said DWR Director Karla Nemeth. “This is a prime example of the threat of extreme flooding during a prolonged drought as California experiences more swings between wet and dry periods brought on by our changing climate.”
One year ago, the Phillips survey showed the seventh highest January measurements on record for that location. However, those results were followed by three months of extremely dry conditions and by April 1 of last year, the Phillips survey measurements were the third lowest on record.
More telling than a survey at a single location are DWR’s electronic readings from 130 stations placed throughout the state. Measurements indicate that statewide, the snowpack’s snow water equivalent is 17.1 inches, or 174% of average for January 3.

“After three consecutive years of drought, the recent series of storms is a good start to the season,” said Jeff Stephenson, water resources manager with the San Diego County Water Authority. “However, we had a similarly strong early winter last year, which did not continue. While the Water Authority and its 24 member agencies have worked and continue to develop diverse water supply sources, there are still opportunities, including rebates, to save more water.”
In San Diego County, watersmartsd.org, provides sources of residential and business rebates, including indoor and outdoor incentives, and free landscape makeover classes.
Stephenson added that the region has reduced its reliance on imported water supplies, including from the Sacramento-San Joaquin Bay Delta, which means more of that source is available for other parts of California.

The January 2023 manual snow survey results are similar to results in 2013 and 2022 when the January 1 snowpack was at or above average conditions, only for dry weather to set in and lead to drought conditions by the end of the water year (September 30).
In 2013, the first snow survey of the season also provided promising results after a wet December similar to today’s results. However, the following January and February were exceptionally dry, and the water year ended as the driest on record, contributing to a record-breaking drought. In 2022, record-breaking December snowfall was again followed by the driest January through March period on record.
“Big snow totals are always welcome, but we still have a long way to go before the critical April 1 total,” said DWR’s Snow Surveys and Water Supply Forecasting Unit Manager Sean de Guzman. “It’s always great to be above average this early in the season, but we must be resilient and remember what happened last year. If January through March of 2023 turn out to be similar to last year, we would still end the water year in severe drought with only half of an average year’s snowpack.”
On average, the Sierra snowpack supplies about 30% of California’s water needs and is an important factor in determining how DWR manages the state’s water resources. Its natural ability to store water is why the Sierra snowpack is often referred to as California’s “frozen reservoir.” A below-average snowpack impacts water users across the state, putting further stress on the environment and critical groundwater supplies.
Due to these increasing swings from dramatically wet to dry conditions, Governor Newsom’s recently released “California’s Water Supply Strategy, Adapting to a Hotter, Drier Future” calls for investing in new projects and technologies that will modernize how the state manages water.

Current climate research indicates the state will see bigger swings from extreme heat and dry conditions to larger and more powerful storms that deliver temporary large boosts to the state snowpack as well as flood risk.
DWR encourages Californians to visit SaveOurWater.com for water saving tips and information, and to continue to conserve California’s most precious resource, rain or shine. DWR conducts five snow surveys at Phillips Station each winter near the first of each month, January through April and, if necessary, May. The next survey is tentatively scheduled for February 1.
As California enters what is expected to be a fourth year of drought, the State Water Resources Control Board is reviewing a request from environmentalists to suspend Los Angeles Department of Water and Power diversions from Mono Lake in the Eastern Sierra Nevada. In its request, the nonprofit Mono Lake Committee argues that the combination of drought and diversions from streams that feed the lake are exposing the lake bottom near islands that host one of the world’s largest nesting gull populations.
Folsom Lake is letting the water flow while rains pick up across the valley. December has provided higher-than-average precipitation for the capital region giving way to cautious optimism about just how much longer the state will be in a drought. But the rainfall also prompted questions about why, in a drought, dams and reservoirs are letting water out instead of holding it in.
All good stories start with a question. So here are five questions for journalists to consider as the record-breaking accumulation of greenhouse gases continues into the opening days of 2023. Climate change, of course, can’t be divided into parts. The answers to these questions, however you devise them, may start small and specific and then, like climate change itself, to borrow the title of a popular 2022 film, illustrate how it is “everything everywhere all at once.”
A series of storms bringing much-needed rain to the San Diego region is also a reminder for residents and businesses to turn off irrigation systems when wet weather is predicted and for at least a week after significant rainfall.
While a series of atmospheric rivers is boosting the Sierra snowpack and easing dry conditions statewide, there is still a long way to go to overcome three arid years. Water-saving actions today can help conserve more of our most precious natural resources when needed.
“Outdoor watering accounts for at least half of a typical household’s water use, which means that cutting back on irrigation during damp and cool periods is one of the easiest ways to live WaterSmart,” said Efren Lopez, a water resources specialist for the San Diego County Water Authority. “With a half-inch of rain in many areas on Tuesday night and several more damp days in the forecast, this is the perfect time to turn off the sprinklers for an extended period.”

Despite the most severe drought conditions in more than 1,200 years, San Diego County continues to have enough water to meet demands due to significant investments in water conservation and supplies. The region’s long-term supply reliability depends on a continued commitment to water-use efficiency indoors and outdoors by homes and businesses both large and small.
Rain barrels are one easy way to save water. “Water stored in rain barrels can gradually be released into landscapes between rains,” said Lopez. “With our region’s traditionally wet months just ahead, this is a great way to increase your outdoor water efficiency.”
The grass beneath the palm trees at the Foothills has no function other than to look lush and inviting for people driving up to the gated community’s entrance. The homeowners’ association there, like many that govern such developments dating to the 1980s and 1990s, was still sprinkling Colorado River water on about 50,000 square feet of turf this year.
Deep uncertainty looms over the Colorado River and the 40 million people who depend on it for their water supply as the basin enters a critical year that could determine its future stability. Plagued by decades of overuse and human-caused climate change, demand for the river’s water has vastly outpaced its supply.
