Latest DWR Snow Survey Reveals Big Gains in Snowpack Levels by Matt Veeh Feb 28, 2019 Water News The Department of Water Resources (DWR) conducted its third snow survey of the year on Feb. 28 at Phillips Station in the Lake Tahoe region of Northern California. The survey results showed significant increases in both snow depth and snow water equivalent levels, which is expected to considerably boost California’s water supply this year, but also comes at the risk of increased flood conditions. Powerful February storms have continued to push statewide precipitation and snowpack levels to well above average for this time of year, with Feb. 28 recorded snow depth and snow water equivalent levels both more than doubling from their Jan. 31 recorded levels. Snow depth: Feb. 28: 113 inches Jan. 31: 50 inches 126% increase Snow water equivalent: Feb. 28: 43.5 inches Jan. 31: 18 inches 142% increase DWR is expected to conduct an additional snow survey in April and possibly another in May, at which time much of the snowpack in California normally begins to melt and turn into runoff that feeds the state’s streams, rivers, lakes, and reservoirs.
