Snowpack is a crucial component of California’s water supply. While heavy winter or spring rains can bring replenishment to streams, rivers, and reservoirs snowpack levels also have a significant impact on water storage and supply. In spring months, long after rains have ceased, warm weather melts snowpack, replenishing reservoirs and rivers.
A slow start to the water year has brought only 11 percent of April 1 averages, and only 26 percent of historic average snowpack. February is typically the wettest month of the water year, so water managers are hopeful that the months ahead will be more plentiful.
