3 Dam, located in Jefferson County, Missouri, was completed in 1949 and serves as a private recreational facility. The dam, classified as an earth dam with a buttress core type, stands at a height of 28 feet and has a storage capacity of 60 acre-feet. The reservoir has a surface area of 3 acres and drains a watershed area of 36 square miles, making it a vital water resource in the region.
Despite being privately owned, Cedar Hill Lake No. 3 Dam is not regulated or inspected by state authorities, posing a high hazard potential due to its age and lack of recent assessments. The dam's emergency action plan and risk management measures are currently not up to date, raising concerns for potential downstream impacts in the event of a failure. With no designated spillway or outlet gates, the dam's condition assessment remains unrated, highlighting the need for improved monitoring and maintenance to ensure long-term safety and sustainability.
Water resource and climate enthusiasts would find Cedar Hill Lake No. 3 Dam an intriguing case study, showcasing the challenges faced by privately owned dams in terms of regulatory oversight and emergency preparedness. As a critical component of the local watershed, the dam's structural integrity and risk management strategies are essential for protecting downstream communities and ecosystems. Continued monitoring and maintenance efforts are necessary to mitigate potential hazards and preserve the dam's recreational and water storage functions for future generations.
