Raritan in Somerset County, New Jersey — The American Northeast (Mid-Atlantic)
Raritan Water Power Canal
1840
The Raritan Water Power Canal was completed in 1842. The Somerville Water Power Company leased waterpower and land along the canal to industry, but was heavily in debt for the expenses of initial construction. In 1863, the company reorganized as the Raritan Water Power Company and improved the dam. By 1881, the company had sold $35,000 in property along the canal, which powered seven businesses, including a gristmill, machine shop and foundry, a paint factory, flour mills, woolen mills, the Somerset Manufacturing Company and the pumping station of the Somerset Water Company. The steady wages received by the mill workers were a major factor in the economic growth of Raritan, which became a town in 1869. By the mid 20th Century, the mills had closed, and the canal was used to provide drinking water to area towns.
In the 1970s, this portion of the canal was filled, and Somerset County Park was built. Because of the significance to local history, on August 27, 2001, The New Jersey State Historic Preservation Office determined that the Raritan Water Power Canal Historic District is eligible for the National Register of Historic Places.
