Charts Show Where California Reservoir Levels Stand After Weeks of Dry Weather

A dry January with little rainfall across much of Northern California actually didn’t hurt the state’s water storage levels, according to data from the California Department of Water Resources.

In fact, thanks to a little snowmelt, water levels were up for all reservoirs from December to January. Lake Mendocino, which has a capacity of 122,400 acre feet, saw the biggest boost from 17% of storage capacity in December to 35% in January. One acre foot is the equivalent of one acre of land covered in one foot of water. Trinity Lake, with a capacity of 2,447,650 acre feet, had the smallest increase from 29% in December to 30% in January.
