Built in 1941, this earth dam stands at a height of 15 feet and spans 422 feet in length, with a storage capacity of 173 acre-feet and a drainage area of 0.3 square miles. The dam serves multiple purposes, including flood control and water supply management for the surrounding area.
Managed by the New York State Department of Environmental Conservation (NYS DEC), Jackson Pond Dam is regulated, permitted, inspected, and enforced by state authorities to ensure its structural integrity and safety. With a spillway type of "Uncontrolled" and a significant hazard potential, the dam underwent a satisfactory condition assessment in July 2019. The emergency action plan (EAP) for the dam was last revised in April 2020, reflecting moderate risk assessment and ongoing risk management measures.
As a vital infrastructure for water resource management in the Chenango County region, Jackson Pond Dam plays a crucial role in mitigating flood risks, providing water storage, and regulating the flow of the Canasawacta Creek. With its strategic location and state oversight, the dam continues to be a key component in safeguarding the local ecosystem and communities against potential water-related hazards and climate impacts.
