Lower Snake River Juvenile Salmon Migration Feasibility Report/ Environmental Impact Statement. Appendix F: Hydrology/Hydraulics and Sedimentation. Appendix G: Hydroregulations. Appendix H: Fluvial Geomorphology

摘要

This Final Feasibility Report/Environmental Impact Statement (RE/EIS) and its 21 appendices document the results of a comprehensive analysis of the four dams on the lower Snake River (collectively called the Lower Snake River Project) and their effects on four lower Snake River salmon and steelhead stocks listed for protection under the Endangered Species Act (ESA). The U.S. Army Corps of Engineers (Corps), along with Bonneville Power Agency (BPA), U.S. Environmental Protection Agency (EPA), and U S Bureau of Reclamation (BOR) as cooperating agencies, analyzed four alternatives to evaluate the best way to improve juvenile salmon migration through Lower Snake River Project.
