The dam stands at 18 feet high and stretches 390 feet in length, with a storage capacity of 115 acre-feet. Situated on Allen Brook, the dam plays a significant role in water resource management in the region, despite its poor condition assessment and significant hazard potential.
The dam's spillway type is uncontrolled, with a width of 32 feet, and it has a maximum discharge of 1075 cubic feet per second. The surrounding area covers 19 acres, with a drainage area of 0.62 square miles. Despite being regulated by the NYS DEC and undergoing state inspection, the dam's risk assessment is moderate, indicating the need for ongoing monitoring and potential risk management measures to ensure the safety of the structure and local residents who could be affected in case of a dam failure. For water resource and climate enthusiasts, Onteora Pond Dam serves as an important case study in the intersection of infrastructure, environmental protection, and community safety.
