Basis for Assessment

The assessments developed for the 1994 and 1996 reports were reviewed and approved by the DNR Fisheries Bureau.   Thus, continue to assess support of both the Class A (primary contact recreation) uses and Class B(LW) aquatic life uses as NS due to high levels of turbidity, and continue to assess support of the fish consumption uses as FS based on results of RAFT fish tissue monitoring in 1991.   Due to the continuing problems with high levels of turbidity, as well as high levels of siltation and nutrients, this lake was placed on the 1998 list of Section 303(d) waters.
