Water storage in the state is supposed to be at its highest this time of year, a sobering forecast of how low water levels may be this coming summer. Lake Oroville is at about 55% of its usual capacity, the LA Times reported. Shasta Lake reservoir is a bit worse—it’s currently at 40% of regular capacity, which is the lowest the lake has been this time of the year since record-keeping began in 1977. The levels are low enough in this reservoir that hydropower generated may be affected for residents in the area, KRCR-TV reported.
