AHSAHKA, Idaho – Water discharge from Dworshak Dam near Orofino, Idaho, will increase moderately beginning tonight from 8 p.m to 9 p.m. and each night through late next week as regional water managers work to control flows from the reservoir into the North Fork of the Clearwater River to meet flood-risk-management requirements.
Dworshak flows are about 12,500 cfs (cubic feet per second) early this evening. Flows will increase 1,000 cfs beginning tonight at 8 p.m., then be increased 1,000 cfs each night between 8 p.m. and 9 p.m. until flows reach 22,000 cfs late next week. The elevation of the Clearwater River is expected to minimally fluctuate during this gradual increase in flows.
Boaters, anglers and other people using waterways both in Dworshak Reservoir and below the dam on the Clearwater River are advised to be alert to changes in water elevation and volume of flow. Current water-management conditions can be viewed on the District website at www.nwd-wc.usace.army.mil/nww/rreports.htm.
Dworshak Powerhouse Unit 3 is out of service from September 2016 through mid-2017 and unable to pass water from the reservoir. The 220,000-kilowatt generator is capable of passing 5,600 cfs through the powerhouse. Units 1 and 2 combined pass 4,800 cfs.
