Assessment Comments
Assessment is based on results of biocriteria sampling data from the biocriteria sampling location (47A6) in O'Brien county.
Basis for Assessment
Divided the B(LR) segment into two equal subsegments. Used the 1990 stream assessment for the dwnstream subsegment and data from biocriteria sampling location for upstream subsegment (this one). Fish and habitat metrics from 1994 stream assessment protocol were applied to the biocriteria data to make assessment.
