A barrage of atmospheric river events that swept across California during the winter and spring has left the state well-positioned when it comes to water storage. As the peak of the snowmelt season begins to slow down, the majority of California’s major reservoirs are at least 90% full – a promising sign for a state that frequently battles drought and associated wildfires. Shasta Lake, California’s largest reservoir, was last reported to be at around 95% capacity, surpassing its historical average by 117%. The reservoir affects 35 California counties and plays a crucial role in managing water for the Sacramento and San Joaquin River watersheds. … Just as notable is Diamond Valley Lake, located about 80 miles southeast of Los Angeles in Southern California. According to data from the California Department of Water Resources, the water basin was at 97% of capacity and 128% above its historical average.
