# Delaware Township, Hunterdon County, New Jersey

Delaware Township is a township in Hunterdon County, in the U.S. state of New Jersey. Part of the township is on the Hunterdon Plateau, while the southern portions are in the Amwell Valley. As of the 2020 United States census, the township's population was 4,560, a decrease of three people (−0.1%) from the 2010 census count of 4,563, which in turn reflected an increase of 85 (+1.9%) from the 4,478 counted in the 2000 census.
The historic community of Sergeantsville is located within Delaware Township, as well as the unincorporated community of Raven Rock.

## History

The township was first settled in the early 18th century by Colonel John Reading (1657–1717), who was instrumental in the creation of Amwell Township in 1708 and also worked for the creation of Hunterdon County in 1714. The Township adjoins the Delaware River on the southwestern portion of Hunterdon County, which provides its name. The state's lone surviving historic covered bridge, Green Sergeant's Covered Bridge, crosses the Wickecheoke Creek between Sergeantsville and Rosemont. The Delaware and Raritan Canal parallels the Delaware River along the southern border of the township. Sergeantsville is at the township's center and includes the municipal building, local public school and Post Office. A "Thanksgiving in the Country" offers a tour of notable homes in Sergeantsville, which raises funds for the Facial Reconstruction Unit of the Children's Hospital of Philadelphia.
Delaware was incorporated as a township by an act of the New Jersey Legislature on April 2, 1838, from a portion of a larger municipality then known as Amwell Township (now defunct). Historian and cartographer John P. Snyder has erroneously stated that a referendum was held on that date, but there was in fact no referendum and the people of Amwell knew nothing about the division until after the Legislature passed the bill. A portion of the township was taken to form Stockton borough (April 14, 1898).

According to the United States Census Bureau, the township had a total area of 37.05 square miles (95.95 km$^2$), including 36.66 square miles (94.94 km$^2$) of land and 0.39 square miles (1.01 km$^2$) of water (1.06%).
