mouth (S24 T77N R21W Marion Co.) to headwaters in NE1/4 SE30 T79N R21W Jasper Co.
Assessment Comments
Assessment is based on results of chemical and biological monitoring conducted as part of the Walnut Creek Watershed Resoration project from 1995-1997.
Basis for Assessment
SUMMARY: The general aquatic life uses remain assessed as "fully supported." EXPLANATION: The aquatic life uses remain assessed as "fully supported" based on results of the chemcial and biologica monitoring conducted on this stream segment in 1995-1997 as part of the Walnut Creek Watershed Monitoring Project (see assessment for the 2000 report above). In part, 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.
