The most recent round of storms to bring precipitation to the area gave us a good soaking and certainly piled it on for the Sierra snowpack.
Professor Jay Lund from UC Davis' center for watershed sciences explains current calculations are only making up some of the difference. there have been years where we saw good amounts of precipitation early on, only to see the rainy season end up being a dry one, but by the end of March into April the numbers won't lie. The Central Sierra Snow Lab reported 214 inches of snowfall for December, and the anual snow survey recorded 78.5 inches of snow depth and a snow water equivalent of 20 inches, 202% of average for this location on this date. The snow water equivalent measures the amount of water contained in the snowpack and is a key component of the Department of Water Resources’ water supply forecast.
Statewide, the snowpack is 160% of average.
