Fish ladders will cost $7 million

WENATCHEE — The thousands of spring chinook already headed up the Columbia River have no idea the amount of work they’ve mobilized at Rock Island and Wanapum dams.

Wanapum Dam investigation delayed by winds

BEVERLY — High winds, including gusts up to 70 mph, convinced Grant County PUD to halt its drilling tests on the fracture of Wanapum Dam until a safe platform to work from is built.

Private wells could also be affected

Private wells for irrigation or drinking water situated near the Columbia River could also be affected by the drawdowns behind Wanapum and Rock Island dams, state Department of Ecology officials say.

Speak out, learn more

The Chelan and Grant PUDs and state Department of Ecology begin outreach to learn about impacts to irrigators from low Columbia River levels.

Wanapum fallout: Power lost, fish migration at risk
