Located in a complex of mills including an early linseed oil mill, an old saw mill, a grainary and the main 1877 stone mill built Samuel Stover on the earlier 1795 stone mill foundations of John Prall's Mill. An earlier frame mill was built here by David Howell, 1711-1720. He sold the mill concern to John Prall in 1794.

Prall's stone mill burned in 1874 and was rebuilt in 1877 by Samuel Stover, who at one time, owned about 30 grist mills in Hunterdon Co, N.J. and Bucks Co., Pa.

The 1877 mill operated into the 1950's before closing and sitting idle. It began to deteriorate with time. In 1976, the Delaware River Mill Society was formed by local citizens to restore and preserve the mill site. The State of New Jersey acquired the site in 1973 in a timely move along with Donald Jones, a local resident who in 1969 saved the mill site from the developers clutches and then sold it to the State. The state hadn't the money for restoration at that time, so the Delaware River Mill Society was formed.
