Old Woman Creek (NERR) State Nature Preserve


Old Woman Creek is protected as a State Nature Preserve and National Estuarine Research Reserve (NERR) because it is one of Ohio's best remaining examples of a natural estuary. The estuary serves as a field laboratory where scientists can study this naturally functioning system and as a place where visitors can learn about estuarine ecology in a natural setting.

An estuary is traditionally defined as that place where the land's fresh waters meet and mix with the saltwater of the sea and where water levels are affected by tides. Although salt concentration or salinity is not a factor here, the waters of the lake and Old Woman Creek combine in the estuary to form a third type of water, chemically different from that of either the creek or lake. 

Old Woman Creek features a variety of aquatic and terrestrial habitats: marshlands, open water, a barrier sand beach, upland forests and old crop fields in early plant succession. Attracted by the water supply and abundance of food and shelter, birds, mammals, fish, reptiles, amphibians and insects are drawn here. Lake Erie and its coastal zone are among Ohio's most valuable natural resources. As many of Ohio's once expansive coastal wetlands have disappeared, the preservation of these natural features is critical.

Trails and Barrier Beach

Nearly three miles of hiking trails wind through an oak-hickory forest to an observation deck overlooking the estuary and through several other habitats. A barrier beach is also located at the north side of the Reserve. Separating the estuary from Lake Erie, the wind-swept barrier beach is a dynamic environment, continually being altered by pounding waves and shifting sand. Shorebirds and migratory waterfowl are common visitors. Only walking/hiking is permitted. Swimming and fishing are not permitted.
