Designed by Daft, McCune & Walker, this earth dam stands at a height of 15.1 feet and has a length of 200 feet, providing a storage capacity of 14 acre-feet. Despite being classified as having a significant hazard potential, the dam's condition assessment remains fair, with the last inspection conducted in April 2021.
The dam's spillway type is uncontrolled, with a width of 10 feet, and it has undergone modification in 1991 for structural improvements. In the event of an emergency, the dam has an Emergency Action Plan (EAP) in place, last revised in June 2021. With a moderate risk assessment rating, the dam is regulated by the Maryland Dam Safety agency and undergoes regular inspections to ensure its operational integrity. For water resource and climate enthusiasts, Velvet Hills South Swm Dam stands as a vital component in mitigating flood risks and protecting the surrounding community in Baltimore County, Maryland.
