This privately-owned Earth dam stands at 14.5 feet in height and spans 300 feet in length, providing a storage capacity of 14.15 acre-feet to manage the runoff from its 0.16 square mile drainage area. The dam's spillway, measuring 66 feet in width, is uncontrolled and contributes to its significant hazard potential.
Despite being assessed as in fair condition as of June 2018, the Neelsville Estates Dam poses a moderate risk according to evaluations, emphasizing the importance of regular inspections. The last inspection in July 2020 revealed the need for continued monitoring and maintenance to ensure the dam's structural integrity and functionality. As climate change impacts water resources, enthusiasts and stakeholders in Maryland are urged to stay informed about the management and safety measures in place for Neelsville Estates Dam to mitigate potential risks and uphold its flood risk reduction capabilities.
