But the dam met its match this year when releases into the river from Shasta and Keswick dams were cranked up to more than 80,000 cubic feet per second.
Heavy steel stanchions were twisted and in some cases broken off. The base plates that hold the stanchions were also damaged and warped; some were knocked off their concrete abutments.
