Prettyboy Reservoir spreads out over 1,500 acres in northern Baltimore County, Maryland. It is named after Prettyboy Creek, which is a located in a section of Baltimore County known as “Devils Backbone”. Legend says that a farmer bought his daughter a colt with a beautiful silken coat. The girl fell in love with the horse and named him Prettyboy. One evening after a storm, the horse wandered off, stopped to have a drink in the stream, and slipped down the soft bank into the water. The horse was never seen again.

Prettyboy Reservoir is owned and operated by Baltimore City, which also owns the surrounding land. Prettyboy is one of three reservoirs created to supply the Metropolitan Baltimore municipal water system. Loch Raven Reservoir, located downstream, and Prettyboy Reservoir provide over half of the drinking water for the entire Baltimore Metropolitan area. Rather than entering directly into Baltimore, the water from Prettyboy is transferred to Loch Raven Reservoir first, via Gunpowder Falls. It then travels via tunnel to the Montebello Filtration Plants in Baltimore where it is treated and distributed to the metropolitan area.

Prettyboy Reservoir lies behind the scenic Prettyboy Dam, completed in 1932, on the Gunpowder River. This area constitutes 20% of all the land in Baltimore County, and is by far the most sparsely populated area in the county. Strict zoning laws prohibit any planned communities from developing here. What this means for the “Lakelubber” is 19 billion gallons of virtually undisturbed aquatic beauty.

If you’re an angler, Prettyboy Reservoir is considered by locals to have the best smallmouth bass in the area. The reservoir also contains brown and rainbow trout, largemouth bass, striped bass, and white perch. Because of the cleanliness of the reservoir, the fish quality is exceptionally high.

Although swimming is not allowed in Prettyboy Reservoir, boating is allowed and is extremely popular. You will need a permit for boating, and there are minimum size requirements for canoes. Prettyboy Reservoir provides a general north/south flow with many branches and streams to explore. Conifers and deciduous trees flank the banks and provide a foundation for the incredible wildlife in the area.

For those who love hiking and animal-watching, Prettyboy Reservoir provides habitat for a variety of forest wildlife species, including white-tailed deer, wild turkey, rabbit, squirrel, and songbirds. The area is open to archery hunting for all game species (except waterfowl) during the regulated hunting season established by the Maryland Wildlife and Heritage Service. Hunters are required to have a permit to access the area. Throughout the year, this area is open to hiking, horseback riding, bird watching, and nature photography. Nearby Gunpowder Falls State Park offers a variety of topographic features, from tidal marshes and wetlands to steep, rugged slopes. There are more than 100 miles of trails, including the 21 mile Northern Central Railroad (NCR) Trail, now known as the Torrey C. Brown Rail Trail in honor of Maryland’s third Department of Natural Resources Secretary.

Prettyboy Reservoir is only minutes from Baltimore City on Interstate 83, and it makes a fun weekend adventure for anyone who enjoys the outdoors.
