Liberty Reservoir CWMA is located in western Baltimore County and eastern Carroll County. The North Branch of the Patapsco River is the primary tributary that feeds the reservoir. Nearly half of the Baltimore County portion of the watershed is forested with large forest blocks in the vicinity of the reservoir.
The 9,200 acre Liberty Reservoir CWMA is owned by the City of Baltimore and is managed to protect the reservoir. The area is open to hiking, rowing or paddle boating, bird watching, horseback riding and nature photography year-round, and for archery hunting during a regulated season. The reservoir is also managed for warm, cool, and cold water fish species and offers excellent fishing opportunities.
The watershed is home to the Liberty Dam that was completed in 1954. Water from the reservoir flows by gravity through a 12.7-mile long, 10-foot diameter tunnel to the Ashburton Water Filtration Plant for treatment in Baltimore City.
The Baltimore Environmental Police safeguard the Baltimore Region’s water supply by protecting the natural resources. In addition, Environmental Police also provide law enforcement services and provide for public safety on all Baltimore City Water Supply Lands and Reservoirs.
