About
Overview
The John W. Flannagan Dam & Reservoir Area boasts an expansive lake nestled in the rolling green Cumberland Mountains of southwest Virginia, offering visitors an oasis of recreation in the summer months. The nearby dam, built primarily for flood control for the Cranesnest and Pound Rivers, creates a breathtaking lake that is maintained at nearly 1,400 feet above sea level. This facility is an ideal spot for picnicking, water activities and hiking.
Recreation
Flannagan's reputation as a fisherman's paradise is well-known. Visitors can enjoy secluded coves of deep, clean water that are well-stocked with bass, walleye and trout. Boating, canoeing, whitewater rafting, and biking top the long list of activities available nearby.
Facilities
The campground offers campsites with electric hookup options, bath houses, playgrounds, launch ramps and picnic shelters with grills and horseshoe pits which provide an ideal location for parties and other get-togethers.
Natural Features
The John W. Flannagan Dam, completed in 1964, carves out a 1,145-acre lake with nearly 40 miles of beautiful shoreline in the lush Virginia mountains.
