A sparse amount of snowfall on the Sierra Nevada Mountains surrounds the low levels of water at the Union Valley Reservoir in El Dorado County Monday January 27, 2014 . The drought is affecting hydroelectric supplies - usually about 15 percent of the state's total. SMUD and other electric utilities are scrambling to put contingencies in place, and while it appears the state will get through the peak summer season, utility executives are praying for rain like everyone else. "We do not have a forecast for blackouts this summer as a result of the drought. It doesn't mean we're not keeping a close eye on it," said Stephanie McCorkle of the California Independent System Operator, which runs the transmission grid.
