Completed in 1924, this earth dam stands at a height of 11 feet and spans a length of 375 feet, creating a reservoir with a maximum storage capacity of 90 acre-feet. The dam regulates the flow of Hibernia Brook and covers a surface area of 11 acres within a drainage area of 2.5 square miles.
Despite being privately owned, Lake Telemark Dam falls under state regulation by the New Jersey Department of Environmental Protection (NJDEP), with regular inspections and enforcement to ensure its structural integrity and safety. The dam has a significant hazard potential but has been assessed as satisfactory in condition, with the most recent inspection conducted in September 2021. While no emergency action plan (EAP) information is provided, the dam is in compliance with state permitting, inspection, and enforcement requirements, indicating a commitment to safety and risk management.
For water resource and climate enthusiasts, Lake Telemark Dam presents a fascinating case study of a privately owned recreational dam that plays a crucial role in managing water flow and providing recreational opportunities in the region. With its historical significance dating back to the early 20th century, the dam's design and construction reflect the engineering practices of the time. As concerns about climate change and extreme weather events grow, the ongoing monitoring and maintenance of dams like Lake Telemark become essential to ensure the safety of communities downstream and the sustainable management of water resources in the area.
