Assessment Comments

Assessment is based on results of a DNR stream use assessment in November 1994. See attached document for details.

Basis for Assessment

(Note:  this 33+ mile stream segment was subdivided into smaller segments in 2001 as part of ADB review and update.  See earlier assessments for this older, larger segment under IA 01-WPS-0160_2.)

SUMMARY:  The Class B(LR) aquatic life uses remain assessed as "fully supported / threatened."  The assessment category, however, is changed from "monitored" to "evaluated."  EXPLANATION:  Continue to use the assessment developed for the 1998 report (see above) that was based on results of the 1994 DNR stream use assessment.   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).
