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 results of an Use Attainability Analysis, this segment is now designated for Class A1 (primary contact recreation) uses. The stream remains designated for aquatic life uses (now termed Class B(WW2) aquatic life uses).
Use Designations
  • Class A1 Recreation : Primary contact
  • Class B(WW-2) Aquatic Life : Warm Water Type 2
