The dam stands at a height of 17 feet with a hydraulic height of 16 feet, providing a storage capacity of 66 acre-feet. Situated on a tributary of the Annisquam River, the dam covers a surface area of 10.1 acres and has a drainage area of 0.51 square miles.
Despite its historical significance, Upper Banjo Pond Dam poses a high hazard potential with a poor condition assessment. The dam, with a length of 149 feet, is regulated by the Department of Conservation and Recreation in Massachusetts, making it subject to regular inspections and enforcement measures. The emergency action plan (EAP) for the dam was last revised in 2013, and its risk assessment indicates a moderate level of risk.
With its unique design as a buttress-type concrete dam, Upper Banjo Pond Dam serves as a vital recreational resource in the area. However, the dam's deteriorating condition and high hazard potential highlight the importance of ongoing maintenance and risk management measures to ensure the safety of the surrounding community and water resources in the region.
