Avista: Water levels can f luctuate


Avista is reminding customers that water level fluctuation on Noxon Rapids and Cabinet Gorge reservoirs is normal and can occur daily.

Avista is able to drawdown the reservoirs in order to generate the power needed to meet demand. Avista does not use drawdowns to suppress fish populations. Drawdown limits were established as a result of negotiations with multiple agencies as well as the public and recorded in the 1999 Clark Fork Settlement Agreement. The protection of the fisheries was a fundamental consideration in setting the drawdown limits we have today and many populations of recreational fish are at all-time highs.

The drawdown limits outlined in the settlement agreement for Cabinet Gorge Reservoir is up to seven feet of elevation any time of the year.

For Noxon Rapids Reservoir, the drawdown limit varies based on the time of year. From mid-May until late September, Noxon Rapids Reservoir is generally held within four feet of full pool, and from October 1 to May 14, drawdowns can be up to 10 feet.

Reservoir users should always be alert to signs of such changes and exercise the highest level of personal caution and safety when using the waterways.
