Des Moines River IA 04-UDM-1212

Prior to the 2008 Section 305(b) cycle, this stream segment was designated only for Class B(WW) aquatic life uses, including fish consumption uses. Due to changes in Iowa’s surface water classification that were approved by U.S. EPA in February 2008, this segment is also now presumptively designated for Class A1 (primary contact recreation) uses. This segment remains designated for warmwater aquatic life use (now termed Class B(WW1) uses) and for fish consumption uses (now termed Class HH (human health/fish consumption uses). Also, the Class C designation is applied to this segment to allow retrieval of data for assessing the support of the Class C uses of the downstream segment: IA 04-UDM-1211.
