Assessment Comments

Assessment is based on results of IDNR/UHL biological (biocriteria) sampling in 1998 (Fish IBI= 62 (good), BM-IBI= 62 (good)).

Basis for Assessment

SUMMARY:  The Class B(LR) aquatic life uses are assessed (monitored) as "fully supported"  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 use support was upgraded to fully supported (FS) based on a comparison of the re-calculated 1998 F-IBI and BM-IBI scores [62 (good), 62(good)] with biological assessment criteria established specifically for the 2002 Section 305(b) report.   See the assessment developed for the 2000 reporting cycle for more information.
