Rain-snowfall year comes up short
SACRAMENTO – (INT) – California’s 2020-21 rainy season turned out to be a dud and new mountain snowpack statistics bear it out.
The fourth Sierra snowpack survey of the season issued Thursday found it only 59 percent of average for April 1st which is when California’s snowpack is the deepest.
The few storms that impacted California have been colder, bringing more snow than rain. This is a positive sign for the Sierra snowpack which accounts for 30 percent of California’s fresh water supply in an average year. For the 2020-21 water year, the snowpack in the Northern and Central Sierra peaked at 70 percent of average, however rain is below 50 percent of average, which ties this year for the third driest year on record.
California’s major reservoirs are at just 50 percent of overall capacity. The amount of water expected to enter California’s reservoirs when the snowpack melts is projected to be just 58 percent of average.
