Assessment Comments
Assessment is based on surveys by the DNR Wildlife Bureau.
Basis for Assessment
Assessed support of the general aquatic life uses as PS based on information from DNR Wildlife Bureau that this wetland is impaired by excessive siltation from nonpoint source delivery of sediment from the watershed and by grass carp that can potentially remove the natural wetland vegetation. Unstable water levels are also a problem for management of this wetland. DNR Wildlife recommended changing the acreage of this waterbody from 450 to 2,500 acres.
