Upper Sylvan Lake Dam, located in Burlington Township, New Jersey, serves as a vital recreational resource in the area, offering a serene escape for water enthusiasts and nature lovers alike. Built in 1941, this earth-type dam stands at a height of 20 feet and spans 600 feet, creating a reservoir with a normal storage capacity of 50 acre-feet. The dam is situated on Mill Stream and is regulated by the New Jersey Department of Environmental Protection (NJDEP), ensuring its safety and compliance with state regulations.

With a significant hazard potential but a satisfactory condition assessment, Upper Sylvan Lake Dam is regularly inspected every two years, with the last assessment conducted in October 2020. The dam's emergency action plan (EAP) was last revised in November 2018, highlighting the importance placed on preparedness and risk management. Although the dam does not have a spillway or outlet gates, its primary purpose of recreation underscores its role as a valuable asset to the community. The dam's location in Congressional District 03, represented by Andy Kim, further emphasizes its interconnectedness with local governance and environmental stewardship efforts.
