Oil sheen
Oil sheen seen in at The Dalles Dam on the Columbia River, Dec. 3, 2020. On Thursday, 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.
