The Millstone River is a 38.6-mile-long (62.1 km) tributary of the Raritan River in central New Jersey in the United States.

The Millstone River begins in western Monmouth County and flows northward through southern Somerset County into the Raritan River at Manville. Almost three quarters of its length is paralleled by the Delaware and Raritan Canal. Both the Millstone River and parallel canal provide drinking water to portions of central New Jersey and provide recreational uses as well.

Course[edit]

The Millstone River starts in western Monmouth County at 40°11′58″N 74°24′37″W / 40.19944°N 74.41028°W / 40.19944; -74.41028, near CR-524 (Stage Coach Road). It flows northeast and turns north before picking up a tributary and crossing CR-1, Sweetmans Lane. It then crosses Baird Road before crossing SR-33 and flowing past the watershed of the Cranbury Brook. It turns west, crossing Perrineville Road and Applegarth Road. Meanwhile, it receives many small tributaries. It crosses I-95, the New Jersey Turnpike, before flowing through the East Windsor Open Space Acquisition. It then crosses CR-639 and Route 130 before picking up a tributary and flowing into Fischer Acres Associates. It crosses Old Cranbury Road and turns southwest before receiving Rocky Brook and making a turn to the northwest. It then turns west and crosses Old Trenton Road, John White Road, and Southfield Road before flowing alongside the West Windsor Planning Incentive and crossing Cranbury Road. It receives Cranbury Brook and Bear Brook before receiving Devils Brook and crossing US-1 (Brunswick Pike). It then flows into Carnegie Lake and crosses the D&R Canal, which it closely parallels the rest of its downstream journey. It turns northeast, receiving Stony Brook from the southwest before turning north again. It receives Harrys Brook and exits the Carnegie Lake. It then enters the D&R Canal State Park before crossing CR-679 (Georges Rd.). It receives Beden Brook before crossing the Griggstown Causeway and receiving the Simonson Brook directly afterward. By the time it receives Beden Brook, it is paralleled by CR-533, River Road. It then receives the Ten Mile Run and Six Mile Run before crossing Blackwells Mills Road. It receives a tributary from Colonial Park and crosses Weston Causeway. It receives Royce Brook before flowing past the Somerset Christian College, one of the few structures built on the land between the D&R Canal and the Millstone River. By the time it crosses Royce Brook, CR-533 has separated from it and turned into Manville. It joins the Raritan River at 40°32′33″N 74°34′0″W / 40.54250°N 74.56667°W / 40.54250; -74.56667.

Flooding[edit]

The Millstone River basin has suffered a number of severe flooding events over the past 200 years. Hurricane Floyd in September 1999 produced a particularly severe flood in the basin, especially in the Lost Valley section of Manville, which sits on a flood plain between the Millstone River and the Raritan River. Severe flooding once again occurred after Hurricane Irene swept through the area in 2011.

Two Millstone River basin flood control and mitigation studies are currently underway by separate governmental bodies to determine if future flooding can be mitigated or controlled:

Water supply[edit]

The Millstone River provides drinking water to tens of thousands of households and businesses in Central New Jersey. A water intake pumping station is located where the Millstone River and Raritan River meet. The water is purified and distributed by the New Jersey American Water.

Commercial history[edit]

In earliest colonial times as land routes began to supplant sea shipping, commerce between the emerging centers New York and Philadelphia was carried by stage coach along a direct route from South Amboy to Bordentown. Much later that route became a railroad. A series of New Jersey towns still extant sprouted up along the stage coach route, including South Amboy, Sayreville, South River, Spotswood, Helmetta, Jamesburg, Cranbury, Hightstown, Windsor, Robbinsville, and Bordentown. In general, the stage coach took a bee-line route, straight as the crow flies, between the Raritan Bay at South Amboy and the Delaware River at Bordentown.

As the country grew and its economy began to thrive, large buoyant barges supported by water on canals emerged as much more suitable for heavy shipping. Unlike the stage coaches, however, routes for canals were obliged to follow the most level land — riverbeds. Hence the importance of the Millstone River which provides a north-south waterway through New Jersey connecting the two great cities of Philadelphia and New York.

The Millstone River is an important tributary of the Raritan River. The Raritan River empties into the Raritan Bay, a bay of the Atlantic Ocean. The Raritan Bay is contiguous to New York Harbor and separates the New York City Borough of Staten Island (Richmond County) from Central New Jersey along with the Arthur Kill a more narrow channel of water between Staten Island and New Jersey.

As the Raritan River flows eastward towards Raritan Bay, it joins the Millstone River flowing north in the vicinity of Bound Brook, New Jersey. The Millstone River traces an arc through several New Jersey Counties, originating in Monmouth County and flowing more-or-less west through Mercer County, then northwest through Somerset County, then northward towards Bound Brook.

Delaware and Raritan Canal[edit]

The Delaware and Raritan Canal runs along east side of the Millstone River for much of its length, from Lake Carnegie in Princeton, New Jersey to the location where the Millstone River empties into the Raritan River in Franklin Township, Somerset County, New Jersey. There the canal continues along the right (south) bank of the Raritan. The land between canal and river is a flood plain that generally consists of swamps, wooded areas and some farmland. A number of spillways allow water to run off from the canal into the Millstone River during periods of heavy water flow.

In Lawrenceville, New Jersey, at a site known as Bakers Basin today located along U.S. Route 1, the canal makes the few mile remaining connection into Trenton, the state capital, and then to the Delaware River.

Hence the Millstone and Raritan Rivers enabled the major shipping route between New York and Philadelphia in the early 19th century. From New York, of course, goods could be shipped north along the Hudson River and Erie Canal to upstate New York, and thence to Western Pennsylvania, Ohio, and other Great Lakes States upstream of Niagara Falls.
