Assessment Comments

Basis for Assessment

Stream assessment form indicates above avg. habitat quality. Very diverse substrate and good pool/riffle sequences observed. Max. depth in pools unknown - too deep to wade. Good diversity of depth, current velocity, and substr. should support a productive and diverse aquatic community. Moderate diversity of fish observed including ch. catfish. Too much water was present to electrofish effectively. River was sampled for RAFT in 1990 and 1991: levels of tech. chlordane in 1991 sample = 0.210 ppm; follow-up in 1991 showed < 0.050 ppm; thus, assess as FST.
