The building of dams and other human-related activities are a significant source of habitat loss for salmon. Specifically, hydroelectric dams on the Columbia and Snake rivers have contributed to habitat loss for key species, mainly Chinook, sockeye, and steelhead. That said, hydropower-funded programs have helped to restore and protect that same important habitat. In 2018 alone, the Bonneville Power Administration spent over $123 million on habitat restoration and protection programs. BPA has spent close to $17 billion since 1981 on fish and wildlife-related activities.
