Presque Isle Bay is the oldest harbor on the Great Lakes. It is formed as Presque Isle peninsula arches north and east into Lake Erie, forming the Bay. Presque Isle State Park forms the northern shore of the Bay. Most of the southern shore of the Bay is bordered by the City of Erie. The western end of the Bay borders Millcreek Township. There are numerous marinas (mostly private) along the south shore of the Bay. The Port of Erie Marine Terminal, Dobbin's Landing, the Maritime Museum and the home of the Flagship Niagara are all located along the southern shore of the Bay. The Bay is about 4.6 miles in length, and about 1.8 miles across at its widest point. The Bay has an average depth of about 20 feet. Use NOAA Chart 14835 (Erie Harbor) for a detailed map of the Bay.
