Passumpsic Hydroelectric Dam, located on the Passumpsic River in East Barnet, Vermont, was completed in 1929 and serves as a crucial source of hydroelectric power in the region. The dam, with a height of 11 feet and a length of 258 feet, has a storage capacity of 70 acre-feet and covers a surface area of 18.3 acres. With a drainage area of 424 square miles and a maximum discharge of 21,400 cubic feet per second, the dam plays a significant role in managing water resources and supporting the local ecosystem.

Owned by a public utility and regulated by the Federal Energy Regulatory Commission, Passumpsic Dam has a low hazard potential and a moderate risk assessment rating. While it does not require state permitting or inspection, the dam's condition assessment is currently not available. Emergency action plans are in place, although last updated in 2014, to ensure the safety of nearby residents in case of any unforeseen events. Overall, Passumpsic Hydroelectric Dam stands as a testament to the importance of sustainable energy generation and water resource management in the face of climate change challenges.
