It decimated the area. The dams cut the salmon off completely from more than 400 miles of open river. They also degraded water quality and supported the growth of toxic algae.

On top of that, the hydropower dams were underperforming and causing more problems than they were worth. COPCO, now PacifiCorp, got only about 2% of its energy from the dams, and it simply wasn’t worth the investment to upgrade them to meet current standards.

Something had to be done.

Four dams were finally destroyed in 2024
