Basis for Assessment

Comments of DNR Wildlife Biologist indicate, in addition to nutrient impacts previously identified, the marsh is impacted by dewatering caused by a drainage ditch that runs adjacent to the wetland.   According to the biologist, "pumping is required nearly every year."  Continue to assess support of the Class B(LW) aquatic life uses as PS.
