A lake in a Northern California town went dry overnight, killing thousands of fish.

Walker Lake, a popular fishing hole near Folsom Lake, is also known as the Mountain Meadows reservoir, and dried up last Saturday, according to CBS13.

"The reservoirs are all continuing to be far below normal," Doug Carlson, a member of the Department of Water Resources, said to CBS13. "We are reliant upon rainfall to fill those lakes of course and until we get more rain we're not likely to see any appreciable increase in the reservoir levels."

Residents said the lake, which is owned by Pacific Gas & Electric Company, drained like a bathtub. The energy company uses the water for hydroelectric power.

"This makes me feel like (electric company officials) didn't want to do a fish rescue and that it was easier to open that sucker up Saturday night," resident Eddie Bauer said to CBS13.

No one opened the dam, the water just ran out, electric company officials said.

"It's the situation we worked hard to avoid but the reality is we're in a very serious drought," Paul Moreno, a spokesman for the electric company, said to CBS13.
