WATERSPORTS -- Generator updating at Nine Mile Dam on the Spokane River will require a further drawdown of Nine Mile Reservoir starting Monday, Avista officials say.

The reservoir already has been lowered three feet since mid-August for the project to replace the original 1906 turbine generating units.

The reservoir must be lowered an additional three feet over two days for a total of six feet, officials said.

The Nine Mile Reservoir drawdown does not affect the water level downstream in Lake Spokane.

In addition, Avista will need to draw the reservoir down 12 feet starting the week of Oct. 27 for approximately one week. This drawdown will allow workers to replace additional equipment. 

While the reservoir is drawn down in late October, Avista will also construct the Nine Mile Boat-Take-Out, which is located upstream of the dam, and will continue its efforts toward removing invasive flowering rush plants along the shoreline.
