Skellinger Lake Dam, located in Sandyston Township, Sussex County, New Jersey, stands as a vital water resource structure along the Spring Cabin Brook. This state-regulated dam, owned by the state government, serves multiple purposes, including flood control and water storage, with a normal storage capacity of 37 acre-feet. With a dam height of 16 feet and a length of 340 feet, this earth and gravity dam plays a significant role in managing water discharge, with a maximum capacity of 1200 cubic feet per second.

Despite its importance, Skellinger Lake Dam is currently assessed as being in poor condition, with a significant hazard potential. The last inspection conducted in August 2021 revealed the dam's deteriorating state, prompting a closer monitoring frequency of twice a year. As a result, the dam's emergency action plan and risk assessment are yet to be prepared, raising concerns about its ability to manage potential emergencies effectively. With its essential role in water management and flood control, efforts to improve the dam's condition and emergency response preparedness are crucial for safeguarding both the environment and nearby communities.
