Liberty Dam is a concrete gravity dam located on the Patapsco River in Maryland. Completed in 1954, it was built primarily for flood control, water supply, and recreation. The dam creates the Liberty Reservoir, which provides drinking water to nearby communities and helps manage water levels downstream. The dam stands approximately 100 feet tall and spans about 1,200 feet across the river. It is operated by the Baltimore City Department of Public Works and plays a crucial role in protecting the surrounding areas from flooding while also offering opportunities for fishing, hiking, and other outdoor activities.
