Prairie Creek IA 02-CED-510

Prior to the 2008 Section 305(b) cycle, this stream segment was designated only for Class B(LR) aquatic life uses. Due to changes in Iowa’s surface water classification that were approved by U.S. EPA in February 2008, and due to completion and approval of a use attainability analysis, the lower portion of this assessment segment is now designated for Class A3 (children’s recreation) use. The upper potion of this segment, however, remains presumptively designated for Class A1 (primary contact recreation) use. Because (1) the water quality criteria to protect Class A1 and A3 uses are identical and (2) incorporation of the new Class A3 designation would require a split in this assessment segment, the entire segment (IA 02-CED-0220_2) will be assessed as a Class A1 (primary contact recreation) water. The stream remains designated for aquatic life uses (now termed Class B(WW2) aquatic life uses.
