The Naval Surface Warfare Center, Dahlgren Division, White Oak Detachment has an underwater acoustic measurements facility consisting of two sites, the White Oak site and Brighton Dam site. The White Oak site consists of a redwood tank which is 30 ft in diameter and 20 ft deep inclosed in a building. The tank is below grade and mechanically isolated from all structures and machinery. The water is constantly filtered and circulated to provide mixing at constant temperature of 72 (degrees)F. The Brighton Dam site is located on Brighton Dam Road, 14 mi north of the NSWC White Oak laboratory. The test barge is anchored and moored 200 ft offshore in approximately 55 ft of water on Triadelphia Reservoir about 1200 ft from Brighton Dam. The reservoir, impounded by Brighton Dam, forms a lake of 800 surface acres containing approximately 7 billion gallons of water. A full range of acoustic measurements are possible at ambient temperature and pressure.
