The Department of Water Resources (DWR) today conducted the fourth snow survey at the Phillips Station snow course. The manual survey recorded 49.5 inches of snow depth and a snow water equivalent (SWE) of 21 inches, which is 83 percent of average for this location. The SWE measures the amount of water contained in the snowpack and is a key component of DWR’s water supply forecast. Measurements from DWR’s electronic snow survey stations indicate that statewide the snowpack’s SWE is 16.5 inches, or 59 percent of average for the date. April 1 is typically when California’s snowpack is the deepest and has the highest SWE.
