About this map

The Agassiz No 2 State Wildlife Management Area anchors the eastern edge of this 1960s landscape, protecting the wetland complex surrounding Lockhart Swamp. This region on the border of Polk Co and Norman Co is defined by an extensive network of drainage infrastructure, including County Ditch No 38, County Ditch No 66, and State Ditch No 68. These engineered waterways reflect the transformation of the Red River Valley for agricultural use, redirecting natural flows like Spring Creek to manage the flat terrain.
