Established by the Iowa Department of Transportation as a wetland mitigation site, Blue Flag adjoins the Great Western Trail. The area emphasizes constructed wetlands in the lowlands 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. The plentiful game and diverse songbird populations make the 138-acres of Blue Flag Marsh a popular destination for hunting and wildlife observation. Many game species including deer, squirrels, raccoons, pheasant, quail, waterfowl, and many furbearing animals are found here. There are no designated trails at Blue Flag, but it is a great area to explore off trail.
