Drought ravages California's reservoirs ahead of hot summer

The drought in the western United States is putting California's reservoirs at dangerously low levels

OROVILLE, Calif. -- Each year Lake Oroville helps water a quarter of the nation’s crops, sustain endangered salmon beneath its massive earthen dam and anchor the tourism economy of a Northern California county that must rebuild seemingly every year after unrelenting wildfires. But now the mighty lake — a linchpin in a system of aqueducts and reservoirs in the arid U.S. West that makes California possible — is shrinking with surprising speed amid a severe drought, with state officials predicting it will reach a record low later this summer. While droughts are common in California, this year's is much hotter and drier than others, evaporating water more quickly from the reservoirs and the sparse Sierra Nevada snowpack that feeds them. The state's more than 1,500 reservoirs are 50% lower than they should be this time of year, according to Jay Lund, co-director of the Center for Watershed Sciences at the University of California-Davis. Over Memorial Day weekend, dozens of houseboats sat on cinderblocks at Lake Oroville because there wasn't enough water to hold them. Blackened trees lined the reservoir's steep, parched banks.
