Built in 1871, this earth dam stands at a height of 36 feet and stretches 800 feet in length, providing a storage capacity of 570 acre-feet. With a primary purpose of water supply, the dam serves the local community by storing water from Hoffman Brook, with a surface area of 23 acres and a drainage area of 4.3 square miles.
Despite its historical significance, Hoffman Creek Dam has been assessed as being in poor condition with a high hazard potential. The last inspection in October 2020 revealed the need for improvements, as the dam's condition was deemed to be at risk. The risk assessment categorized the dam as having a moderate risk level (3), prompting the need for risk management measures to ensure the safety and stability of the structure.
As a significant water resource infrastructure in Chemung County, New York, Hoffman Creek Dam is subject to state regulation and inspection by the NYS DEC. With its critical role in water supply and the potential risks associated with its current condition, stakeholders must prioritize maintenance and upgrades to ensure the long-term resilience and safety of this essential structure for the community.
