Sunset Lake is a medium-sized reservoir located in and near the city of Bridgeton in southern New Jersey (Cumberland County). The reservoir lies mostly in the townships of Hopewell Township and Upper Deerfield Township. The lake was created by damming a stream that feeds to the area from above Seeley Lake. And a stream that feeds into the lake from the nearby Mary Elmer Lake also located in Bridgeton. The dam is located next to Park Drive, a major roadway that cuts throughout the city's park system and interconnects with Route 49. Just across the turnpike in Deerfield it opens over in the "Silly Pond". The water from Sunset Lake flows over the spillway dam and into the Cohansey River.
