Notes:
Prior to the 2008 Section 305(b) cycle, this river segment was designated only for Class B(WW1) 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 and the results of an Use Attainability Analysis, this segment is also now 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).
Use Designations
  • Class A1 Recreation : Primary contact
  • Class BWW1 Aquatic Life : Warm Water Type 1
