Lake Madeleine, located in Bennington, Vermont, is a private hydroelectric reservoir with a dam constructed in 1957 by Haley & Aldrich. The dam, primarily made of earth and stone, stands at a height of 65 feet and spans a length of 1700 feet, creating a reservoir with a storage capacity of 873 acre-feet. The lake covers a surface area of 35 acres and is fed by Hopper Brook, serving as a vital water resource in the region.

Despite its age, Lake Madeleine's dam is assessed to be in fair condition, with a significant hazard potential. The last inspection in 1978 revealed no major issues, and the dam is currently not regulated by the state. However, the owner is responsible for its maintenance and upkeep as it continues to provide hydroelectric power in the area. The reservoir's scenic location and historical significance make it a valuable asset for both water resource and climate enthusiasts to explore and appreciate.

As an important piece of Vermont's hydroelectric infrastructure, Lake Madeleine offers a glimpse into the region's renewable energy efforts and water management practices. With its picturesque setting and functional purpose, the reservoir serves as a reminder of the intersection between human innovation and environmental stewardship. For those interested in water resources and climate resilience, Lake Madeleine presents a unique opportunity to study the impact of hydroelectric power on local ecosystems and communities, making it a compelling destination for exploration and research.
