Built in 1930, this earth dam stands at a height of 30 feet and stretches 600 feet in length, creating a storage capacity of 230 acre-feet. The dam overlooks Catlin Brook and holds a normal storage capacity of 180 acre-feet, covering a surface area of 41 acres.
With a high hazard potential, the dam has been deemed to be in satisfactory condition as of the last assessment in July 2020. It is regulated by the Connecticut Department of Energy and Environmental Protection (DEEP) and undergoes regular inspections every two years. Despite its recreational focus, the dam's critical role in water resource management and flood protection cannot be overlooked, making it of interest to water resource and climate enthusiasts seeking to understand the complex interplay between infrastructure, nature, and human activity in safeguarding our waterways.
