Basis for Assessment

SUMMARY:  The Class A (primary contact recreation) uses were considered "not assessed."  The Class B(LW) aquatic life uses were assessed as "fully supported / threatened."  Fish consumption uses were "not assessed."  EXPLANATION:  The Class A uses were considered "not assessed" due to lack of information on levels of indicator bacteria at this lake.   At the recommendation of the DNR Fisheries Bureau, the Class B(LW) uses were changed from "partially supported" to "fully supported / threatened."  The water quality trend for this lake is "improving."  According to the DNR Fisheries Bureau, the water quality improvements at Five Island Lake reflect results of the lake dredging project.   The fish consumption use remain "not assessed" due to lack of fish tissue monitoring at this lake.
