14-031 Dworshak to decrease discharge flows tonight at midnight plus Saturday midnight to begin refilling reservoir; Boaters and anglers should remain alert to changes in water elevation and flow

Published May 2, 2014

AHSAHKA, Idaho – Discharge flows from Dworshak Dam into the North Fork of Clearwater River will be decreased late Friday night and again on Sunday morning to begin refilling Dworshak Reservoir, according to U.S. Army Corps of Engineers water-management officials. Flows will decrease Friday night at midnight from approximately 10,700 c.f.s. (cubic feet per second) to about 5,000 c.f.s. At midnight on Saturday, flows will be further reduced from 5,000 c.f.s. to about 2,400 c.f.s.

The Corps has been releasing water from Dworshak Reservoir for flood risk reduction purposes during spring runoff. The Corps adjusts space for flood risk reduction operations as the reservoir refills to augment fish recovery operations in the lower Columbia-Snake rivers system later in the season.

Corps officials advise boaters, anglers and other people in or near the reservoir or Clearwater River to be alert to changes in water elevation and volume of flow, especially this time of year.

Current water-management conditions can be viewed online 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 2012, 1.98 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.
