PORTLAND, Ore. --
On Thursday, Dec. 3, a thrust hub cooling water pipe broke, spilling up to 200 gallons of oil into the Columbia River at The Dalles Dam. The equipment is part of a fish unit turbine designed to provide attraction water for migrating fish.
The U.S. Army Corps of Engineers, Portland District is dedicated to rapid spill responses and is in the process of containing as much oil as possible. The turbine is now isolated from the river.
“Our goal is to respond swiftly during oil spill responses,” said Dwane Watsek, Operations Division chief. “Our team at The Dalles took immediate actions to remove the unit from service and contain and clean up oil with booms and skimmers,” he said. “The unit will remain out of service and isolated from the river until technicians assess and repair it.”
Corps technicians are assessing how much oil actually spilled into the river, as some of the 200 gallons may be contained in a draft tube or collection channel within the dam.
Corps officials notified partner agencies, including National Response Center, Oregon and Washington emergency management offices and the Columbia River Intertribal Fish Commission.
