Avista to lower Long Lake reservoir

Thu., Jan. 6, 2011, 11:14 a.m.

Beginning Friday, Avista Corp. will start lowering the reservoir behind Long Lake Dam.

Water levels will drop about a foot per day over the next two to three weeks to help control Eurasian milfoil, an invasive water weed. The 14-foot drawdown from summer lake levels also allows waterfront property owners to undertake state and locally permitted shoreline projects.

Avista officials said property owners and lake-users should prepare for the shifting ice and low water conditions by removing boats from the water, securing docks and boathouses and taking other measures to prevent property damage. Boaters should be alert to changing water levels.

Weather conditions and dam maintenance work can affect the drawdown rate.
