Assessment Comments
Stream use assessment in Linn County.
Basis for Assessment
Used results of DNR stream use assessment in September 1991 to assess support of the B(LR) aquatic life uses as FST due to (1) habitat score (24) better than the overall average score (22) for DNR stream use assessments, (2) fish score (9) slightly lower than 75th percentile for DNR stream assessments made with seines (10), but field notes indicate that rocky substrate hindered seining, and (3) personal communication from DNR biologist Paul Sleeper that Indian Creek is a high quality stream with a very diverse fish population. Much of the watershed of Indian Creek is urban and impacts due to urban NPS runoff are likely.
