Built in 1964 by the US Army Corps of Engineers, the dam serves multiple purposes including flood risk reduction, fish and wildlife pond, and recreation. It has a hydraulic height of 44 feet and a structural height of 46 feet, with a maximum storage capacity of 8,590 acre-feet and a normal storage of 1,490 acre-feet. The dam spans 3,020 feet in length and has a spillway width of 340 feet to manage water levels during high flow events.
The dam has a high hazard potential and is regularly inspected by the US Army Corps of Engineers to ensure its structural integrity and readiness for emergency situations. The risk management measures in place include continuous monitoring of the dam's condition, prioritization of activities to mitigate risks, and engagement with local emergency managers and the public to raise awareness and readiness for potential dam-related emergencies. The USACE regularly updates the emergency action plan for the dam and performs maintenance and repairs as needed to ensure its proper functioning. Despite the efforts to manage flood risks associated with the dam, there is always a level of risk involved, especially during severe weather events that may overwhelm the dam's capacity.
