Mercer Lake, also known as Lake Mercer, is a man-made lake within Mercer County Park in West Windsor, Mercer County, New Jersey, United States. The lake came into being with the 1975 construction of a dam to control flooding on the Assunpink Creek in nearby Trenton by the United States Department of Agriculture Soil Conservation Service (now the Natural Resources Conservation Service). The basin now occupied by the lake was excavated by crews building nearby Interstate 295 at no additional cost to taxpayers. The lake is the home of one of the US Olympic Rowing Team's training centers. It has played host to the 1988, 1992, 2004 and 2008 U.S. Olympic Team Trials for Rowing, in addition to USRowing National Team selection events, international regattas, and both collegiate and junior national championship regattas. The infrastructure and topography of the racecourse meets FISA standards and PNRA has the equipment necessary to host the world's largest regattas.
Mercer Lake is also known for fishing. Mercer Lake is home to many fish including Largemouth Bass, Bluegill, Pumpkinseed Sunfish, Yellow Perch, catfish, Shady, Musky and Alabama Turkey fish. Although Mercer Lake is one of cleanest bodies of water in central New Jersey, it still faces problems with pollution from nearby golf courses and storm water runoff.
