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 siltation and extreme water level fluctuations associated with a large contributing watershed area, in addition to a serious exotic macrophyte (purple loosestrife) infestation, are impairing wetland uses. Biologist recommeded that the support of the aquatic life uses of this wetland be assessed as PS.
