The Jennings Randolph Lake project (originally called Bloomington Lake) consists of a rolled earth and rockfill dam, rising 296 feet from the lake bottom. The dam, dike, and spillway extends 2130 feet across the valley.  At its full conservation pool, the lake is approximately 6.6 miles long with a surface area of 915 acres. The project became operational in 1981. Project purposes include flood risk management, water quality, low flow augmentation, water supply, and recreation.

Tucked between Garrett County, Maryland, and Mineral County, West Virginia, Jennings Randolph Lake stretches along 5.5 miles of spectacular countryside on the North Branch of the Potomac River. The area is renowned for its unspoiled wilderness and natural beauty. The lake provides a sanctuary for countless birds, animals and fish where nature comes first and having fun is a close second.

Recreation opportunities at Jennings Randolph Lake include boat ramps for fishing and boating, beach and picnic areas, and the Robert W. Craig campground.  Whitewater releases are made each spring from the dam's outlet works.
