AHSAHKA, Idaho – Dworshak will be releasing water during the next two weeks to manage reservoir refill and provide flood control. Reservoir managers will maintain Dworshak Dam releases at 1,700 cubic feet per second (cfs) through Feb. 19.

Flows may vary from Feb. 20 to Feb. 28 in the range of 1,700 to 4,000 cfs to meet the flood risk management (FRM) target elevation of 1536.2 feet in the Dworshak reservoir. There will not be within day load shaping for power during the remainder of February.

The Corps works with regional water managers, other agencies and tribes, and fish managers and hatcheries in joint efforts to keep total dissolved gasses below the Idaho State maximum threshold, when possible.

For safety, the public is advised to be aware of the danger associated with fluctuating river flows and elevations. The river at this time of year is deep, cold and fast, so extreme caution should be used near riverbanks. 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 up or down in water elevation and volume of flow.
