Lake Information for Liberty Lake


This 1,225 hectare (3,100 acre) impoundment was completed on July 8, 1954. It was constructed by the City of Baltimore for use as a public water supply. The dam crest is at an elevation of 126 m above sea level, and water overflowed the crest for the first time on February 6, 1956.

The North Branch of the Patapsco River is the primary tributary that feeds the reservoir. Other tributaries include Beaver Run, Keyer's Run, Prugh Run, Morgan Run, Locust Run, and Cooks Branch. Reservoir length is 18 km with a shoreline length at full pool of 131 km. The average depth is 59 ft with a maximum depth of 144 ft.

Boat propulsion is limited to rowing, paddling, or battery-powered motors. A seasonal permit issued by the City of Baltimore Reservoir Natural Resources Office is required prior to launching a boat in Liberty Reservoir. Shoreline fishing is permitted.

Due to the potential for zebra mussel infestations, boaters on Liberty, Loch Raven, and Prettyboy Reservoirs must sign an affidavit stating their boat will be used only on these reservoirs. Live bait is prohibited unless purchased from a Maryland certified zebra mussel-free bait store.

Fishing Description: 

The reservoir is managed for warm, cool, and cold water fish species. Largemouth bass, smallmouth bass, along with bluegill, crappie, and white perch are the most popular warmwater fish. Photo of the State record striped bass caught by Robert Bruce in 2000.White crappie and the bass often reach trophy size. White perch still average about 10 inches despite being very plentiful in the reservoir.

Striped bass were stocked between 1981 and 1984. They have been reproducing naturally since 1986 so expect to catch a variety of sizes, with some of the stocked fish now in the 40-pound range. This reservoir also supports a fine walleye fishery, sustained by good natural reproduction. A 12-pound walleye was surveyed recently.
