Basis for Assessment
SUMMARY: The Class B(LW) aquatic life uses were assessed as "fully supported / threatend." EXPLANATION: Based on a review of the previous (1998) assessment (see above) by the DNR Wildlife Bureau, the support of the Class B(LW) aquatic life uses was changed from "partially supported' to "fully supported / threatened." The primary threat remains siltation from agricultural nonpoint sources.
