Assessment Comments

Assessment is based on results of an IDNR stream use assessment in October 1994.

Basis for Assessment

SUMMARY:  The Class B(LR) aquatic life uses remain assessed (evaluated) as "fully supported."  Due to the age of the data, however, the assessment category, however, is considered "evaluated."   This assessment is the same as that developed for the 2002 reporting cycle.

EXPLANATION:  Continue to use the assessment developed for the previous reporting cycles that was based on results of the 1994 IDNR stream use assessment (see the assessment developed for the 1998 report for more information).   However, because these data are now considered too old 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).
