Basis for Assessment
SUMMARY/EXPLANATION: The Class B(LW) 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 previous assessment/listing cycles. The fish consumption uses remain "not assessed" due to the lack of water quality information upon which to base an assessment.
Fish consumption uses remain "not assessed" due to the lack of fish contaminant monitoring. In general, Iowa wetlands are not managed for recreational fisheries; thus, fish contaminant monitoring is not typically conducted at these waterbodies.
