Assessment Comments
There was not enough recent data (<5 years old) to complete an assessment.
Basis for Assessment
SUMMARY: The Class A (primary contact recreation) uses and the Class B(WW) aquatic life uses are considered "not assessed." Fish consumption uses remain "not assessed." EXPLANATION: The assessment of support of the Class A and Class B(WW) uses developed for previous reports (see above) were based, in part, on results of DNR quarterly water quality monitoring near Larabee (station 911060). Data from this station, however, were last collected from October 1993 through September 1995 and are thus considered too old (greater than five years) for characterizing current water quality conditions. As part of DNR's expanded water quality monitoring program, monthly monitoring at the Larabee station began in October 1999. Results from this monitoring will allow development of an updated assessment of support of beneficial uses for the 2002 report. Fish consumption uses remained "not assessed" due to the lack of recent fish tissue monitoring in this river reach. The most recent monitoring was conducted in 1992 near the Linn Grove Dam as part of the EPA/DNR fish tissue (RAFT) monitoring program. These data are considered too old (greater than five years) for characterizing current levels of fish contaminants.
