Assessment Comments
Assessment is based on results of fish surveys conducted by DNR Fisheries Bureau in 1997 and students from Cornell College in 1997.
Basis for Assessment
SUMMARY: The Class B(LR) aquatic life uses remain assessed as "fully supported." EXPLANATION: The aquatic life uses remain assessed as "fully supported" based on results of the biological monitoring conducted on this stream segment in 1996 and 1997 (see assessment for the 1998 and 2000 reports). These data are approximately five years old and, according to IDNR's methodology for Section 305(b) assessments, are thus appropriate for characterizing current water quality conditions.
