Prettyboy Reservoir is located in northwest Baltimore County on the Gunpowder River.
The location was originally home to the paper mill of land owner William Hoffman. Its dam was constructed in 1932, and supplements an additional 19 billion gallons of capacity to its downstream neighbor, Loch Raven.
Although the origins of the name are not clear, the local legend tells a story of a farmer who had a beautiful white colt named “Pretty Boy” that was the pride of the neighborhood. However, one stormy day a flash flood swept the horse into the raging Gunpowder River and he was lost forever. After the reservoir was constructed, the name was kept as a tribute to the lost colt.
Today, Prettyboy offers some of the most pristine and peaceful waters in Maryland. With a local society doing its best to curb development in the watershed, Prettyboy gives a sense of wilderness that is evident in its vast array of fauna and flora.
As far as fishing goes, Prettyboy is primarily known for smallmouth and perch. It also is home to blue catfish, carp, and crappie. There is a single boat ramp off of Spooks Hill Road, and all boats must have a Liberty / Prettyboy reservoir permit. Due to zebra mussel concerns, any watercraft used here must only be used in Loch Raven, Liberty, or Prettyboy reservoirs. This is strongly enforced, as zebra mussel infestations have forced the reservoir to be shut down in the past.
There are several shoreline fishing spots available near the bridges, with off-road parking available. Several trails wind through the woods, but are often overgrown and may be difficult to navigate. Hikers should also be cautious, as the Prettyboy watershed is very popular for hunter as well.
