Basis for Assessment

[NOTE:  For the 2002 report, the waterbody identification number for this wetland was changed from "IA-WETLAND-20" to "IA 06-WED-00015-L."  This wetland is not in the current (2002) version of the Iowa Water Quality Standards and is thus classified only for "general uses."  This wetland has not been proposed for inclusion to the standards as a Class B(LW) waterbody.]

SUMMARY:  The general aquatic life uses were assessed (evaluated) as "fully supported / threatend" based on information from the IDNR Wildlife Bureau.   Other beneficial uses are "not assessed."  This assessment is the same as that developed for the 2002 reporting cycle.  

EXPLANATION:  Based on a review of the previous (2000) assessment by the DNR Wildlife Bureau, the support of the aquatic life uses of this wetland remain "fully supported / threatened."  According to the local IDNR biologist (Priebe), the primary threat remains flooding-related siltation from agricultural nonpoint sources and problems with water level fluctuation related to the controlled flows of the nearby Missouri River.
