After years of being used as a sportsman’s club, investigations showed that the marsh had high levels of lead. The U.S. Fish and Wildlife Service, River Action, Quad City Audubon Society, and Iowa DNR came together to try to save the marsh and conserve its biotic community. The EPA declared the marsh a Superfund Site and began an extensive cleanup of the lead. After the cleanup, wildlife and plant life showed a vast improvement. So much so, that it was decided to make the wetland a nature preserve and Nahant Marsh Education Center was born. Click here for our EPA Cleanup Presentation.
The Nahant Marsh preserve is the largest urban wetland on the Upper Mississippi River. It is comprised of marshy areas, mesic, wet and sand prairie, and bottomland forest. A spring-fed quarry, known as Carp Lake, and the surrounding grounds, are part of the Nahant Marsh preserve as well. The 305-acre preserve is owned by the City of Davenport and the Nahant Marsh Board, a 501(c)(3) nonprofit organization. Conservation and restoration efforts on the preserve are directed by the Nahant Board. The educational programming is overseen by Eastern Iowa Community Colleges (EICC).
