Basis for Assessment
Waterbody not designated for beneficial uses in the Iowa Water Quality Standards as of June 1996. This publicly-owned waterbody was added to the list of Iowa wetlands in 1994 at the suggestion of the DNR Wildlife Bureau.
Comments of DNR Wildlife Biologist indicate the wetland is impacted by siltation and nutrients from agricultural nonpoint sources. The use support status would be FST if the wetland was designated for B(LW) uses. For purposes of Section 305(b) reporting, consider the aquatic life uses of this wetland to be fully supported/threatened.
