Assessment Comments

Previous assessment was based on occurrence of fish kill in August 1998.

Basis for Assessment

SUMMARY:  The general aquatic life are "not assessed."  EXPLANATION:  The previous (2000) assessment of the aquatic life uses ("partially supported") was based on the occurrence of a fish kill im 1998 (see assessment for the 2000 report above).   According to IDNR's assessment methodology, however, the absence of a fish kill in the three-year period following a fish kill suggest that impacts from the kill have dissipated.   Thus, due to the lack of a subsequent kill in this stream reach over the last three years (1999, 2000, and 2001), and due to the lack of other water quality information upon which to base an assessment of support of the aquatic life uses, the previous assessment of the aquatic life uses was changed to "not assessed."
