Assessment Comments

Habscr/fshscr: 20/12 (fish score incorrect on field sheet (14) due to incorrect No. species & % tolerant); 1998 Biocriteria: Fish IBI= 49(fairly good), BM-IBI= 56(good).

Basis for Assessment

SUMMARY:  The Class B(LR) aquatic life uses remain assessed as "fully supported / threatened" (minor impacts).   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.
