Dingmans Ferry is an unincorporated community in Delaware Township, Pike County, Pennsylvania, United States. As of 2014, it had a population of 7,477 people. It was originally sited on the Delaware River, in an area now included in the Delaware Water Gap National Recreation Area. When the Corps of Engineers acquired the land by eminent domain in the mid-twentieth century for the creation of the Tocks Island Dam project, it relocated the community further up the hill.Local objections to the dam and purchasing of land willingly or by eminent domain had delayed the project for years, but preparations ended for certain when it was learned that the proposed dam site was on a fault line. When the dam project was cancelled, the National Park Service was tasked with managing the property for the Corps so far as public use was concerned. The land purchased by the Corps was converted to the Delaware National Recreation Area.
