Completed in 1953, this earth dam stands at a structural height of 130 feet and has a maximum storage capacity of 7,200 acre-feet. The primary purpose of Cold Brook Dam is flood risk reduction along Cold Brook Creek, with a spillway width of 200 feet to manage excess water during peak flow events.
Managed by the US Army Corps of Engineers, Cold Brook Dam poses a high hazard potential due to its location and design. Despite the risks associated with dam failure, the Corps diligently monitors and maintains the structure to mitigate potential threats. An Emergency Action Plan is in place, with regular inspections and risk assessments conducted to ensure the dam's integrity and the safety of downstream communities.
As part of risk management measures, the Corps collaborates with local emergency managers and the public to raise awareness and preparedness for potential dam-related emergencies. Regular maintenance and repairs are carried out to address any issues that may arise, emphasizing the importance of proactive measures in safeguarding the surrounding area from flooding events.
