A U.S. Federal Court in Seattle, last month issued a ruling intended to protect salmon and steelhead in the Columbia River from rising water temperatures that can exceed 70 degrees in lakes created by hydropower dams. The Clean Water Act bars the temperature in the river from exceeding 68 degrees. Cold water species such as sockeye and steelhead become stressed at temperatures over 68 degrees and stop migrating when the temperature exceeds 74 degrees. The ruling instructs the Environmental Protection Agency to come up with a plan to address the dam’s impact on water temperature. The ruling comes at the same time EPA and state officials are trying to address a request from the Trump Administration to increase water deliveries to farms and cities.
