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.
As summer temperatures increase, snowpack has begun to melt causing flood concerns for some already high rivers. However, the snowpack is still very deep in the mountains and skiers are expected to enjoy the snow through the summer.
