mouth (S4 T95N R39W O'Brien Co.) to headwaters in S15 T96N R40W O'Brien Co.
Assessment Comments
Assessment is based on results of 1996 biocriteria sampling: Fish IBI = 55 (good) 14 species, 4 families, BM-IBI = 53 (fair).
Basis for Assessment
SUMMARY: The general aquatic life uses remain assessed as "fully supported / threatened" (minor impacts). The assessment category, however, is changed from "monitored" to "evaluated." EXPLANATION: Continue to use the assessment developed for the 1998 and 2000 reports that was based on results of the 1996 IDNR/UHL biocriteria assessment. However, because these data are now considered too old (greater than five years) to accurately characterize current water quality conditions, the assessment category is changed from "monitored" (indicating an assessment with relatively high confidence) to "evaluated" (indicating an assessment with relatively low confidence).
