Reservoir levels will fluctuate during turbine tests for Nine Mile Dam

Water levels in the reservoir behind Nine Mile Dam on the Spokane River will fluctuate when Avista Utilities starts testing new turbines for the dam’s generator.

The testing will begin Sunday, with a reservoir drop of up to 4 feet expected over a two-day period. Other short-term drawdowns will occur during the turbine testing, which will continue through late August. Discharges from the dam will also vary.

Avista is encouraging property owners to secure docks and recreationists to be aware of the potential for changing water levels.
