Assunpink Creek

Assunpink Creek is a 22.9-mile-long (36.9 km) tributary of the Delaware River in western New Jersey in the United States.

Assunpink Creek (from the Lenape Ahsën'pink, meaning "stony, watery place") is born in rural Monmouth County, about a mile north of Clarksburg. Flowing westwards, it soon enters the Assunpink Wildlife Management Area, where it has been dammed to form Rising Sun Lake. After an unnamed tributary enters from the south, it enters another reservoir, Assunpink Lake. The two lakes, as well as Stone Tavern Lake on the tributary, are popular fishing spots.

Below Assunpink Lake, the creek flows under Old York Road and flows into Mercer County. New Sharon Branch enters the creek from the south at Carsons Mills. The creek now turns northwest, passing under the New Jersey Turnpike and then U.S. Route 130, just southwest of Windsor. Here, it finally exits the Wildlife Management Area.

Still further northwest, the creek enters Central Mercer County Park. Bridegroom Run enters from the north side as the creek turns west and is impounded to form Mercer County Lake. A small wildlife management area, the Van Nest Refuge, lies along the stream just below the dam. It then passes under Quaker Bridge Road and Interstate 295 before turning southwest and paralleling the Delaware and Raritan Canal. The creek now enters a heavily built-up area. Miry Run enters near Hutchinson Mills. The canalized stream flows past the Trenton Rail Station and finally empties into the Delaware River in Trenton.
