Publication Summary

Five dams, on the Columbia River in eastern Washington, generate nearly one-quarter of the power created by the Columbia River within Washington State. While they are a vital source of electricity, they also have some side effects which can produce high levels of total dissolved gas, increase river temperatures, and change fish habitat. When hydropower project operators for these dams renew their federal licenses they must show that they will meet Washington State water quality standards. This story describes how several government agencies, tribes, and other interested parties worked together, during the dam relicensing process, to identify actions which may help to reduce or remove negative impacts caused by the dams.
