This photo taken in September 1997 shows that this boulder weir on Indian Creek at Mile 11.7 survived high flows. The pool in the foreground was formed partially as a result of scour around the large boulder cluster/root wad placed by Klamath National Forest.

An intact boulder weir at Mile 11.7 of Indian Creek in September 1997. Clean gravels above the weir indicate a redd under construction by fall Chinook salmon. The plunge pool below the weir also provides excellent rearing habitat for juvenile salmonids. Photo provided by Al Olson, Klamath National Forest.
