Greens, anglers join Columbia River fight

摘要

Fishing and environmental groups yesterday waded into Washington state's fight with the Trump administration over temperature limits for the Columbia River to protect the Pacific Northwest's rapidly dwindling salmon runs. At issue is a complicated regulatory struggle between the state and the Trump administration over the state's Clean Water Act authority that could have a major impact on the survival of the region's endangered salmon runs. In May, Washington for the first time exercised its authority to require federal dam operators to address the temperature of water in reservoirs. Dams stop the flow of the Columbia River and its tributaries, forcing water to stagnate and heat up to temperatures that are lethal to migrating fish like salmon (Greenwire, May 11).
