If Cougar were to completely fail, that water would rush 60 miles down the McKenzie River, washing away everything in its path, until it reached the Eugene and Springfield area.
The deluge could make Eugene and Springfield look like Corvallis, Oregon City and Portland after the Flood of 1996; although no dams failed during that event. That image, and the desire to do everything possible to keep it from becoming reality, was the backdrop for a recent inspection at Cougar Dam, May 24.
