Assessment remains based on information from the IDNR Wildlife Bureau.

Basis for Assessment

This waterbody is not in Iowa's current surface water classification (http://www.iowadnr.gov/water/standards/files/swcdoc2.pdf) and is thus classified only for general uses.   As such, only the general use protection for aquatic life will be assessed.    

SUMMARY/EXPLANATION:  The aquatic life uses remain assessed (evaluated) as "fully supported” based on information from the IDNR Wildlife Bureau.   This assessment is the same as that developed for the previous assessment/listing cycles (not impaired).
