Assessment Comments
Assessment is based on results of three DNR stream use assessments in August 1995.
Basis for Assessment
[NOTE: In November 2001, the original waterbody segment (IA 02-CED-0480-0, from confluence with Burr Oak Cr. to the IA/MN state line) was split into the following segments (1) from Burr Oak Creek to Stacyville Impoundment (IA 02-CED-0480-1) and (2) from Stacyville Impoundment to the IA/MN state line (IA 02-CED-0480-2). The assessment for the 2002 report is based on the assessment for the original waterbody (IA 02-CED-0480-0).]
SUMMARY: The Class B(WW) aquatic life uses remain assessed as "fully supported / threatened" (minor impacts). The assessment category, however, is changed from "monitored" to "evaluated." Fish consumption uses remain "not assessed." EXPLANATION: Continue to use the assessment developed for the 1998 and 2000 reports (see above) that was based on results of the three 1995 IDNR stream use assessments. 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). Fish consumption uses remain "not assessed" due to the lack of fish contaminant monitoring in this stream segment.
