Haneys Mill is a section of Walpack. A grist mill was built there around 1860. It appears on the Sussex County wall map of that year with a nearby sawmill, a lime kiln, and residences of C. Haney, J.W. Fuller and B.D. Fuller. Serving at various times as a gristmill, a sawmill and a cidermill, the last operator was Jake Haney. The mid-nineteenth century farmhouse of the Haney family also stood nearby. Some of the scenes from the 1933 Ford Motor Company promotional film "These Thirty Years" were filmed here. In the movie, the place was known as the Haines farm; across the road in front of the house were the barns where the auction scene was filmed.
After the floods in the 1950s, which raised the water of the Delaware above the level of the roads alongside it, a
controversial project to build a hydroelectric dam and reservoir on the Delaware River in the 1950s and 1960s led to government's seizure of land in northwestern New Jersey and northeastern Pennsylvania under the authority of the U.S. Army Corps of Engineers. The construction of the dam would have created a lake reservoir that would have flooded the Walpack Valley. For political and geological reasons, the dam project was deauthorized and the land transferred to the management of the
