The mighty Columbia and Snake Rivers once produced the most abundant salmon runs on Earth. Today 13 different populations of salmon are listed as threatened or endangered under the Endangered Species Act, primarily due to the presence and operation of dams. We have a multi-pronged, basin-wide strategy to help salmon that includes modernization of the Columbia River Treaty, removal of four dams on the lower Snake River, improving water quality and restoring fish passage at the three dams that make up the Hells Canyon Complex.
