With a height of 31 feet and a length of 900 feet, the dam has a storage capacity of 540 acre-feet and serves as a vital resource for the surrounding area. Managed by the Connecticut Department of Energy and Environmental Protection (DEEP), the dam is inspected regularly to ensure its structural integrity and maintain its satisfactory condition.
The dam's primary purpose is to provide water supply, drawing from Wintergreen Brook and covering a surface area of 43.5 acres. With a high hazard potential due to its location, Lake Wintergreen Dam has a maximum discharge capacity of 850 cubic feet per second and a spillway width of 50 feet. Despite its age, the dam continues to meet regulatory standards and is equipped to handle emergency situations, with an established Emergency Action Plan (EAP) updated as recently as 2016.
Lake Wintergreen Dam is not only a functional structure but also a historical landmark, serving as a testament to the engineering achievements of the past. Its importance in providing water resources to the community and its ongoing maintenance efforts reflect a commitment to preserving both the environment and the infrastructure for future generations. For water resource and climate enthusiasts, Lake Wintergreen Dam stands as a reminder of the critical role dams play in sustaining our ecosystems and communities.
