14-090 Dworshak discharge flows to temporarily change

Published Nov. 24, 2014
AHSAHKA, Idaho – Water discharge from Dworshak Dam near Orofino, Idaho, will temporarily fluctuate on Tuesday, Nov. 25, between 7 a.m. and 2 p.m. while U.S. Army Corps of Engineers staff complete required maintenance on a main breaker in the power house, operations officials at the dam announced today.

Discharge flow from the dam will be increased from approximately 1,100 c.f.s. (cubic feet per second) to about 1,600 c.f.s. during the scheduled maintenance outage. This temporary change in flows will likely result in less than a one-half-foot increase in water depth in the Clearwater River near the confluence with the North Fork.

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. Current water-management conditions can be viewed on the District website at www.nwd-wc.usace.army.mil/nww/rreports.htm -- click on “Hourly” and look in the “TOTAL” column under the “OUTFLOW” heading on the reservoir report. Reservoir elevation is found in the “FOREBAY” column under the “EL AT POWERHOUSE” heading.

During fiscal year 2013, 1.84 billion kW hours of electrical power were produced by Dworshak Dam’s three generating units. Since Dworshak Dam became operational in June 1972, it has prevented about $2.8 million in potential local flood damages.
