Completed in 1990, this earth dam stands at 25 feet tall and stretches 340 feet in length, with a storage capacity of 34 acre-feet. Its primary purpose is flood risk reduction, serving as a crucial resource in managing stormwater and protecting the surrounding area from potential inundation.
Managed by the local government and regulated by the Maryland Dam Safety agency, Railroad Branch SWM Pond is considered to have a high hazard potential due to its unsatisfactory condition assessment. The pond has a drainage area of 0.2 square miles and a maximum discharge capacity of 6314 cubic feet per second. Despite its critical role in flood risk management, the dam's current condition raises concerns about its ability to withstand potential emergencies and calls for proactive risk management measures.
With an inspection frequency of one year and a moderate risk assessment rating, Railroad Branch SWM Pond requires ongoing attention and maintenance to ensure its effectiveness in flood risk reduction. The presence of an uncontrolled spillway and a spillway width of 50 feet further emphasize the importance of regular monitoring and upkeep to prevent any potential failures. As water resource and climate enthusiasts, it is crucial to stay informed and engaged in the preservation and maintenance of essential infrastructure like Railroad Branch SWM Pond to protect our communities and environment from the impacts of extreme weather events.
