DWR via Maven’s Notebook —
The Department of Water Resources (DWR) today conducted the second snow survey of the season at Phillips Station. The manual survey recorded 22.5 inches of snow depth and a snow water equivalent of 8 inches, which is 46 percent of 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. Statewide, the snowpack is 65 percent of average for this date.
On January 1, the statewide snowpack was 108 percent of average after a series of large storms in November and December boosted snow totals in the Northern Sierra, but significant regional differences kept the Central Sierra just below average and the Southern Sierra well below average. An excessively dry January has pushed the Northern Sierra back to near average, the Central Sierra to 58 percent of average, and has led the Southern Sierra Nevada to fall to under 50 percent of average.
“Despite a good start to the snowpack in the Northern Sierra in November and December, we can look back as recently as 2013 and 2021 to show how quickly conditions can change for the drier,” said DWR Director Karla Nemeth. “California missed out on critical snow-building storms in January which has pushed the state down below average for this time of year. While we are excited to see some storm activity in the coming days, sustained periods of no precipitation can dry the state out very quickly. For each day it’s not snowing or raining, we are not keeping up with what we need.”
