Segment Memos 1
Prior to the 2008 IR cycle, this segment had Class A (primary contact recreation), Class B(WW) warmwater aquatic life (including fish consumption), and Class C (drinking water) designated uses. Due to changes in Iowa’s surface water classification approved by U.S. EPA in 2008, this segment now has Class A1 (primary contact recreation), Class BWW1 warmwater aquatic life, Class C (drinking water), and Class HH (human health/fish consumption) designated uses.
