This is a Legacy Assessment. Assessments prior to 2016 were developed under the previous USPEA guidelines, and have a different format.

Assessment Comments

Assessment is based on results of IDNR/UHL biological (biocriteria) monitoring in 1998: Fish IBI= 49(fairly good), BM-IBI= 56(good).

Basis for Assessment

SUMMARY: The Class B(LR) aquatic life uses are assessed (monitored) as "fully supported / threatened" (minor impacts) based on results of IDNR/UHL biological (biocriteria) sampling in1998. This is the same assessment as that developed for the 2002 reporting cycle.

EXPLANATION: The aquatic life uses remain assessed as "fully supported / threatened" based on results of the biological monitoring conducted on this stream segment in 1998 (see assessment for the 2000 report). These data are less than five years old and, according to IDNR's methodology for Section 305(b) assessments, are thus appropriate for characterizing current water quality conditions.
