The reservoir is called Franklin Delano Roosevelt Lake, named after the United States President who presided over the dam's authorization and completion. Creation of the reservoir forced the relocation of over 3,000 people, including Native Americans whose ancestral lands were partially flooded. While the dam does not contain fish passage, neither does the next downstream dam, Chief Joseph Dam. This means no salmon reach the Grand Coulee Dam. The third large dam downstream, Wells Dam, has an intricate system of fish ladders to accommodate yearly salmon spawning and migration.
