Assessment Comments
Stream use assessment in Linn County.
Basis for Assessment
Used results of DNR stream use assessment in August 1991 to assess support of B(LR) aquatic life uses as FST due to (1) habitat score (25) better than overall avg (22) for DNR stream use assessments, (2) field notes regarding habitat ("very nice pools and riffles; large rocks), (3) fish score (11) better than 75th percentile for DNR stream use assessments made with seines, (4) field notes indicating that seining was difficult due to rocky substrate, thus helping explain the relatively low diversity of species collected.
