Assessment Comments

Assessment remains based on surveys by IDNR Wildlife Bureau.

Basis for Assessment

SUMMARY:  The aquatic life uses remain assessed (evaluated) as "fully supported" based on information from the IDNR Wildlife Bureau.   The primary contact recreation and fish consumption uses remain "not assessed" due to the lack of water quality information upon which to base an assessment.   This assessment is the same as that developed for the previous (2004, 2006, and 2008) assessment/listing cycles.  

EXPLANATION:  The aquatic life uses remain assessed as "fully supported" based on information from the Iowa DNR Wildlife Bureau.   This waterbody remains in IR Category 2a.  

The primary contact recreation uses remain "not assessed" due to a lack of water quality information upon which to base an assessment.   In general, Iowa wetlands are not managed to support primary contact recreation.  

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.
