Basis for Assessment
Continued to use the assessment of support of the Class A primary contact and Class B(LW) aquatic life uses developed for the 1994 report (both=FST). This assessment was reviewed by the DNR Fisheries Bureau. The DNR Fisheries biologist noted that DNR has worked with NRCS to construct a new sediment control pond; thus, the water quality of this lake may be improving. At the recommendation of the DNR Fisheries Bureau, this lake was placed on the 1998 list of Section 303(d) waters due to siltation from nonpoint sources and due to excessive growth of aquatic macrophytes.
