Mud Creek IA 06-BSR-1546

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, this segment was presumptively designated for Class A1 (primary contact recreation) uses. Due to changes in Iowa’s surface water classification that were approved by then Iowa Department of Natural Resources on June 17, 2015, this segment is now designated as Class A1 (primary contact recreation) uses and is no longer considered a presumptive Class A1 water. The stream remains designated for aquatic life uses (now termed Class B(WW2) aquatic life uses).
