Established by the Iowa Department of Transportation as a wetland mitigation site, Bulrush emphasizes constructed wetlands in the lowlands and bottomland timber. Bulrush named for one of the wetland plants that can be found there. The plentiful game and diverse songbird populations make the 151-acres of Bulrush Marsh a popular destination for hunting and wildlife observation. Many species including deer, squirrels, raccoons, waterfowl, and many furbearing animals are found here. Access to this area is from County Road R63. There is a small parking lot and a narrow pedestrian lane leading to to main area. Currently, a canoe or kayak would be needed to cross North River to the main area.
