Assessment Comments

Assessment based on reports by IDNR Wildlife Bureau.

Basis for Assessment

Comments from the DNR Wildlife biologist indicate that the aquatic life uses of this wetland are "partially supported" due to siltation from agricultural nonpoint sources and due to an infestation of purple loosestrife that is causing substantial habitat degradation.
