UPDATE: Central and So California can expect little rain through end of January suggests forecast models
SACRAMENTO, Calif. – The Department of Water Resources (DWR) today conducted the first Phillips Station snow survey of the season. The manual survey recorded 30.5 inches of snow depth and a snow water equivalent of 10.5 inches, which is 93 percent of the January 1 average for this 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. While conditions were positive at Phillips Station, statewide the snowpack is just 52% of average for this date.
“The snow survey results reflect California’s dry start to the water year and provide an important reminder that our state’s variable weather conditions are made more extreme by climate change,” said DWR Director Karla Nemeth. “We still have several months left to bring us up to average, but we should prepare now for extended dry conditions. The Department, along with other state agencies and local water districts, is prepared to support communities should conditions remain dry.”
On average, the Sierra snowpack supplies about 30 percent of California’s water needs and the snowpack 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.”
