Lake Madeleine Dike in Vermont is a private structure designed by HALEY & ALDRICH for hydroelectric purposes. Completed in 1957, this earth dam stands at a height of 25 feet and has a structural height of 28 feet, with a length of 1100 feet. The dam has a storage capacity of 475 acre-feet and covers a surface area of 35 acres, with a drainage area of 0.53 square miles.

Located in Bennington, Vermont, in the city of SANDGATE, the Lake Madeleine Dike holds significant hazard potential and has not been rated for its condition assessment. The last inspection was conducted in August 1978, with an inspection frequency of 10 years. Despite its state jurisdiction, the dam is not regulated or inspected by the state, posing potential risks to the surrounding area in case of failure. Water resource and climate enthusiasts may find this structure intriguing due to its historical significance and operational purpose in the Green River-TR watershed.
