Avista to Begin Lake Spokane Drawdown
Water level to drop up to a foot per day


Avista Utilities will start to draw down the water level at Lake Spokane (Long Lake Reservoir) the week of December 28, 2009. It is expected that the reservoir will be lowered up to one foot per day for a two- to three-week period, dropping the level of the lake 13 to 14 feet below its maximum summer elevation of 1,536 feet.


Under the right (extreme cold) weather conditions, the drawdown is expected to help with control of Eurasian milfoil, an invasive weed found in many area waterways. The drawdown also allows for repair and construction by property owners along the lake shoreline.


Property owners and lake-users are reminded to make any necessary preparations, including removing boats from the water and securing docks and boathouses for low-water conditions.


Water levels are subject to change due to a variety of factors, such as weather or equipment problems at the Long Lake dam. Lake users should always be alert to signs of such changes and exercise the highest level of personal caution and safety when using the waterways.


Updated reservoir level information is available by calling Avista's recorded Lake Information Line at (509) 495-8043.
