BOISE -- Time is running out for fans and tourists to see Shoshone Falls at their peak summer splendor.
Idaho Power officials say they are getting ready to lower flows of the Snake River that feed the spectacular water falls near Twin Falls.
The utility intends to lower volumes significantly on the river by Friday. In the last few weeks, Idaho Power has been releasing water stored at the American Falls Reservoir to generate electricity at dams downstream -- and thus boosting volume spilling over Shoshone Falls.
Flows on the Snake River peaked at 2,500 cubic feet per second Thursday. Idaho Power will throttle down flows to about 600 cubic feet per second by Friday night.
