On March 25, 1999, the National Marine Fisheries Service (NMFS) listed the anadromous Oncorhynchus mykiss (O. mykiss), or steelhead, population in the Middle Columbia Evolutionarily Significant Unit (ESU) as threatened under the Endangered Species Act, and deemed that the federal Columbia River Hydropower System (FCRPS) posed jeopardy to this ESU. To mitigate for the impacts of the dams, the FCRPS Biological Opinion issued by NMFS, emphasized improving spawning and juvenile rearing habitat in the tributaries to achieve recovery of the population.
