Assessment Comments
Assessment based on results of October 1995 IDNR stream use assessments conducted near Diamond Center and the results of assessments conducted near Aurelia in 1992.
Basis for Assessment
Combined results of the DNR stream assessments in October 1995 near Diamond Center with results of assessment near Aurelia in 1992 to assess support of the Class B(LR) aquatic life uses as PS due to continued impacts from (1) extensive channelization, (2) pasturing of riparian zone, and (3) lack of substrate diversity (i.e., domination by sand/silt substrates).
