Old Woman Creek National Estuarine Research Reserve

Old Woman Creek National Estuarine Research Reserve is the smallest reserve in the National Estuarine Research Reserve System at 573 acre. It is one of two Great Lakes-type, freshwater estuaries in the system; the other being Lake Superior National Estuarine Research Reserve. Located in Erie County, Ohio near Sandusky, the reserve features freshwater marshes, swamp forests, a barrier beach, upland forest, estuarine waters, stream and nearshore Lake Erie. Photographic atlases containing descriptions and identifications of many of the invertebrates found at Old Woman Creek have been prepared by Dr. Kenneth Krieger of the National Center for Water Quality Research at Heidelberg University.
