Avista to Begin Lake Spokane Drawdown
Water level to drop up to a foot per day over a two-to-three week period
SPOKANE, Wash. Dec. 28, 2015: Avista Utilities will start to draw down the water level at Lake Spokane (Long Lake Reservoir) on Dec. 31, 2015. Operators expect to lower the reservoir, up to one foot per day over a two-to-three week period, until it reaches its winter drawdown elevation of 13 to 14 feet below the normal summer elevation of 1,536 feet.
Under the right weather conditions, which include sustained periods of single-digit temperatures and little or no snow on the exposed lakebed, the drawdown is expected to help control Eurasian watermilfoil and other invasive aquatic weeds found in Lake Spokane. The drawdown also allows shoreline homeowners the opportunity to complete state and locally permitted repair and construction projects along the lake shoreline.
Property owners and lake-users are reminded to make necessary preparations, including removing boats from the water, and removing or securing docks and boathouses to accommodate shifting ice and low-water conditions. Floating and removable docks are less susceptible to damage from shifting or changing ice levels.
The lower winter elevation will be maintained as long as river flows allow. However, during the drawdown period water levels are subject to change due to a variety of factors, such as weather (rain on snow events in the upper drainages) or maintenance 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.
Customers can access waterflow information at avistautilities.com/waterflow or if you prefer the information is available on a 24-hour telephone information line. You will find notification of anticipated elevation changes on Lake Spokane, the Spokane River and Coeur d’Alene Lake. In Washington call (509) 495-8043 and in Idaho call (208) 769-1357.
The recorded information is provided to advise shoreline property owners, commercial and recreational users of changes in the lake and river elevation levels that may affect plans for water use.
