Basis for Assessment

SUMMARY: The Class A (primary contact recreation uses) were "not assessed." Continued to assess support of the Class B(LW) aquatic life uses as "fully supported / threatened." Other beneficial uses remain "not assessed." EXPLANATION: The level of support of the Class A (primary contact recreation) uses was changed from "fully supported / threatened" to "not assessed" due to the lack of information on levels of indicator bacteria at this lake. This change in assessment reflects a change in the DNR's Section 305(b) assessment methodology and does not reflect any known change in water quality. The previous (1998) assessment of support of the Class B(LW) uses ("fully supported / threatened") was reviewed and approved by the DNR Fisheries Bureau in 2000. Fish consumption uses remain "not assessed" due to the lack of fish contaminant monitoring at this lake.
