  • History and Establishment
    The land was acquired between the late 1960s and the early 1970s. It consists of 50-plus pieces of property, which included many farms. Ground was broken for the lake in June 1971.  Because of the construction of Routes I-95 and I-295, the lake basin was excavated at no cost to the county.  The county sold the gravel to the highway contractors, which in turn helped excavate the basin now known as Lake Mercer.   At the peak of excavation there was one truckload of gravel leaving the area per minute from 7 a.m. to 7 p.m., six days per week.

    Today, Mercer County Park encompasses over 2,500 acres covering areas of the Townships of West Windsor, Hamilton and Lawrence. The Park has year-round facilities for all ages and includes both active and passive recreational opportunities.

  • Did You Know Facts
    Man Made?  The dam was built to control flooding by the Assunpink Creek to protect certain sections of the city of Trenton. This project turned a marsh into a man-made lake for boating and fishing, which led to the development of the boathouse and marina and eventually the entire surrounding park.

    In a typical year the park attracts over 400,000 athletes/participants/users and over 430,000 spectators.

    There are full time Mercer County Park Rangers that patrol all MCPC facilities year round, 7 days a week. Each is certified in First Aid, CPR, & AED , and can be seen on foot, mountain bike, ATV or SUV.

    The National Softball Association recently awarded the MCPC with its "Outstanding Parks Award" for the softball fields and facilities in Mercer County Park.
