Site details

Dale Hollow is one of the clearest reservoirs in Tennessee and draws divers from hundreds of miles away. The most popular dive is the submerged foundation of the old Willow Grove Schoolhouse, part of a village flooded when the dam was completed in 1943, reached easily from the Willow Grove campground and marina area. Old roads, barn foundations and other ghost-town traces remain on the bottom, with the schoolhouse outline sometimes visible from the surface.
