The dam is primarily designed for flood risk reduction along Holmes Run, with a maximum storage capacity of 785 acre-feet and a normal storage level of 179.9 acre-feet. The dam stands at a height of 26.5 feet and stretches 201.5 feet in length, regulating a drainage area of 2.48 square miles.
Managed by the Department of Conservation and Recreation in Virginia, Fairview Lake Dam has a high hazard potential but was assessed to be in satisfactory condition as of May 2020. The dam undergoes regular inspections, with the last one conducted in May 2020, to ensure its structural integrity and safety. Despite its critical role in flood risk reduction, the dam does not have an Emergency Action Plan prepared, highlighting the need for proactive emergency preparedness measures to mitigate potential risks to the surrounding community.
Situated under the jurisdiction of the Baltimore District, Fairview Lake Dam plays a vital role in regulating water flow and protecting the surrounding area from flooding. With its strategic location and crucial purpose, the dam serves as a significant asset in water resource and climate management efforts in Fairfax, Virginia.
