Assessment Comments

Assessment based on the following: (1) DNR fish kill database, three kills in Jones/Linn County and (2) DNR Biocriteria sampling: fish 31 spp., 6 families, Fish IBI = 80 (excellent), BM-IBI= 72 (good).

Basis for Assessment

SUMMARY:  The Class B(WW) aquatic life uses remain assessed as "fully supported / threatened" (minor impacts).   Fish consumption uses remain "not assessed."  EXPLANATION:  Continue to use the assessment of the Class B(WW) uses developed for the 1998 report (see above).   This assessment was based on results of the DNR biocriteria survey conducted in August 1996.   No fish kills have been reported for this reach since August 1996.   Fish consumption uses remain "not assessed" due to lack of fish contaminant monitoring in this stream reach.
