Basis for Assessment
Changed the assessment of overall support for the Class A primary contact recreation uses from "not supporting" to "partially supporting at the recommendatin of the DNR Fisheries Bureau. DNR Fisheries indicated that the water quality impairments and WQ trend previously identified for this lake (i.e., organic enrichment, nutrients, and aquatic plants due to natural shallowness and internal nutrient cycling, with a stable water quality trend) remain accurate.
