Assessment Comments
Assessment based on surveys by IDNR Wildlife Bureau.
Basis for Assessment
SUMMARY: The aquatic life uses remain assessed (evaluated) as "fully supported / threatened" (minor impacts). Fish consumption uses remain "not assessed." EXPLANATION: The aquatic life uses remain assessed as "fully supported / threatened" based on information from the Iowa DNR Wildife Bureau (see assessment for the 1998 and 2000 reports above). Fish consumption uses remain "not assessed." In general, Iowa wetlands are not managed for recreational fisheries; thus, fish contaminant monitoring is not typically conducted at these waterbodies.
