Columbia River Basin salmon and steelhead populations were once the world's largest. Before 1550, an estimated 16 million salmon and steelhead returned to the basin annually to spawn. Over the past 25 years, however, the number of salmon and steelhead returning to the Columbia River Basin has averaged around 660,000 per year, although annual population levels have varied widely. Various factors have contributed to the long-term decline including over-harvesting, the construction and operation of dams, the degradation of spawning habitat, increased human population, and unfavorable weather and ocean conditions. The population decline has resulted in the listing of 12 salmon and steelhead populations in the basin as threatened or endangered under the Endangered Species Act (ESA). Once a species is listed as threatened or endangered, the ESA requires that efforts be taken to allow the species to recover. The Department of Commerce's National Marine Fisheries Service (NMFS) is the lead agency responsible for the recovery of the threatened or endangered populations of Columbia River Basin salmon and steelhead. The recovery of a species entails the development and implementation of a plan for the species' conservation and survival. The ESA also requires other federal agencies to consult with NMFS before they take any action that may jeopardize the continued existence of listed salmon or steelhead populations in the Columbia River Basin. You asked us to (1) identify the roles and responsibilities of the federal agencies involved with the recovery of Columbia River Basin salmon and steelhead, (2) determine how much they have spent collectively on recovery efforts, and (3) determine what recovery actions they have undertaken and what they have accomplished.

Return to the River will describe a new ecosystem-based approach to the restoration of salmon and steelhead populations in the Columbia River, once one of the most productive river basins for anadromous salmonids on the west coast of North America. The approach of this work has broad applicability to all recovery efforts throughout the northern hemisphere and general applicability to fisheries and aquatic restoration efforts throughout the world. The Pacific Northwest is now embroiled in a major public policy debate over the management and restoration of Pacific salmon. The outcome of the debate has the potential to affect major segments of the region's economy - river transportation, hydroelectric production, irrigated agriculture, urban growth, commercial and sport fisheries, etc. This debate, centered as it is on the salmon in all the rivers, has created a huge demand for information. The book will be a powerful addition to that debate. A 15 year collaboration by a diverse group of scientists working on the management and recovery of salmon, steelhead trout, and wildlife populations in the Pacific Northwest Includes over 200 figures, with four-color throughout the book Discusses complex issues such as habitat degradation, juvenile survival through the hydrosystem, the role of artificial production, and harvest reform

Columbia River Basin salmon runs were once the world's largest. By 1996, however, returning adult salmon had been greatly reduced in number. This report addresses how well the U.S. Army Corps of Engineers is implementing its Columbia River Fish Mitigation program. Provides information on (1) the Corps' decision-making process for identifying, setting priorities for, & funding actions to help the recovery of salmon runs, & (2) whether the Corps has been completing its fish mitigation actions on schedule & within budget. Determines why the Corps had not entered into an agreement with the Bonneville Power Administration for the cost of operating their dams in the Basin. Charts & tables.
