Assessment Comments
Assessment is based on results of a DNR stream use assessment in August 1994.
Basis for Assessment
[Note: For the 2002 report, the previous waterbody segment for Bear Creek (IA 02-IOW-0180-2), which extended 21 miles from Little Bear Creek to Highway 146 in Poweshiek County, was split into two subsegments: (1) from L. Bear Cr. (S16, T80N, R13W, Poweshiek Co.) to confluence with unnamed tributary in SW 1/4, S9, T80N, R14W, Poweshiek Co. (IA 02-IOW-0180-2) and (2) unnamed tributary (SW 1/4, S9, T80N, R14W, Poweshiek Co.) to confluence with unnamed tributary at Hwy 146 crossing at west line, S21, T81N, R16W, Poweshiek Co. (IA 02-IOW-0180-3).]
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 IDNR stream use 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).
