WENATCHEE, Wash. (AP) -- The big drawdown of the reservoir behind Wanapum Dam has stabilized a cracked spillway there, but it's coming at the cost of lost power generation.
Wanapum Dam has the ability to generate some 700 megawatts this time of year. The drawdown, which dropped the level of the reservoir by 26 feet, has reduced generation to 360 megawatts.
The Wenatchee World reports that no financial-impact estimates were available from the Grant County Public Utility District, owner of the Columbia River dam.
But the Chelan County PUD, owner and operator of the two dams immediately upriver of Wanapum, has had to stop all power generation at its Rock Island Dam. That means power with an estimated daily market value of more than $400,000 is no longer being generated there.
