Established by the Iowa Department of Transportation as a wetland mitigation site, Blue Flag adjoins the Great Western Trail.  The area emphasizes constructed wetland in the lowland and reestablished prairie on the associated uplands.
Blue Flag is named for the Blue Flag Iris that can be found here.  They are a perennial plant found in shallow water along the shoreline.
