How California’s reservoirs will change after atmospheric river hits
California will escape much of the rainfall from an incoming atmospheric river, but the storm will still benefit some of the state’s reservoirs. An atmospheric river is forecast to saturate much of the Pacific Northwest over the next week. … The incoming storm could bring up to 2 inches of rain to two of the state’s northern lakes. … Lake Shasta is at 126 percent its historical average, but still at only 68 percent capacity. Trinity Lake is at only 49 percent capacity, a far cry from its historical average of 86 percent. Rainfall is anticipated to begin on Friday and continue through Wednesday.
