Resident Fish in the Columbia River Basin

Abstract

Abstract Development and operation of Columbia River Basin hydroelectric facilities have contributed to the reduction in diversity and abundance of some native resident fish. To mitigate for effects of hydroelectric development and operations, the Bonneville Power Administration (BPA) annually funds fisheries research and management efforts. In 2003, the BPA provided $19.2 million for the implementation of 54 resident fish projects that were recommended for funding by the Columbia Basin Fish and Wildlife Authority and Northwest Power and Conservation Council through the council's Columbia River Basin Fish and Wildlife Program.

Managers must ensure that power, water management, and land-use dec...
