In 1983, the City of Rockville proposed building a 21-foot tall gabion dam in the woods above the Pipestem entrance to the park to aid with stormwater management. The proposed structure would have stood 18 feet above the streambed and would have been topped with a 3 foot wooden railed walkway (in total, about the height of a 2-story Fallsmead home). According to residents at the time, during a major storm, the dam would cause water to back up behind it and create an 18-foot deep lake. Residents opposed the dam, and it was obviously never built.
