Assessment Comments

Previous assessments were based on 1995 DNR biocriteria sampling (habscr/fshscr = 29/11 (shock)).

Basis for Assessment

SUMMARY:  The Class B(CW) aquatic life uses are "not assessed."  Fish consumption uses remain "not assessed."  EXPLANATION:  The information upon which the previous assessment of aquatic life uses was based was collected in 1995 (see above); these data are now considered too old (greater than five years) for accurately characterizing current water quality conditions.   Thus, support of the aquatic life uses was changed to "not assessed."  Fish consumption uses remain "not assessed" due to the lack of recent fish tissue monitoring data for this stream reach.
