Mainstem amendments

In April 2003, the Council followed a nearly two-year public process by adopting mainstem amendments to its Columbia River Basin Fish and Wildlife Program with a description of river conditions and tests of dam operations intended to protect all fish and wildlife that utilize mainstem rivers as habitat.
