Sitting on the Yantecaw Brook, the Great Notch Reservoir Dam has a high hazard potential but has been assessed as satisfactory in terms of condition. The dam's last inspection in June 2021 revealed its structural integrity, and emergency preparedness measures are in place. Although the dam has not undergone significant modifications over the years, its operation and maintenance are crucial for ensuring the safety and security of the surrounding community in the event of any unforeseen emergencies.
With its rich history dating back over a century, the Great Notch Reservoir Dam remains a key component of New Jersey's water infrastructure. As climate change continues to impact water resources, the proper management and maintenance of dams like Great Notch are essential for safeguarding the region's water supply and adapting to changing environmental conditions.
