SHASTA LAKE, Calif. (AP) - California officials have relaxed water quality rules to help protect endangered salmon in the Sacramento River after a dry winter.
At issue is the temperature of the river water. Water that is too warm could kill the salmon, so officials typically release water from Shasta Lake to keep the river cool.
But with the low amount of precipitation this year, there isn't enough water available.
So the State Water Resources Control Board in May loosened certain water quality rules, among them the location in the river where officials have to meet a 56-degree temperature standard.
The Sacramento Bee reports that the goal is to reduce the amount of cold water released from the lake through the summer, allowing the supply to stretch into the fall
