AHSAHKA, Idaho – Water discharges from Dworshak Dam near Orofino, Idaho, will increase from 5,800 cubic feet per second (c.f.s.) to 9,900 c.f.s. on Saturday, Feb. 14, to manage the reservoir for seasonal flood-control-space objectives, U.S. Army Corps of Engineers water-management staff at the Walla Walla District announced today.
The increase in flows will begin at about 1 a.m. and gradually ramp up to 9,900 c.f.s. during the next two to three hours which will raise water levels near the Clearwater River confluence less than foot, according to Walla Walla District water managers.
“Based on the Feb. 1 water-supply outlook, we are targeting an end-of-month reservoir elevation of 1,560 feet to ensure adequate room for anticipated inflows,” said Steve Hall, the District’s water management program manager. “Right now, the reservoir level is about 35 feet from full pool (elevation 1,600 feet), so we have quite a bit of water to release in order to meet that target elevation.”
Corps officials advise boaters, anglers and other people using waterways both in Dworshak Reservoir and below the dam on the Clearwater River to be alert to changes in water elevation and volume of flow.
