On February 23, 2004, the 770 ft (230 m) long, 1910 hydroelectric Embrey Dam was demolished, using 600 lb (270 kg) of explosives, by divers from an engineering detachment at Fort Eustis. [2] The aim of removal was to re-open miles of spawning grounds to aid populations of American Shad , herring, catadromous American eel, and other species. [ 3 ]

The project site was to have been 4.6 miles (7.4 km) east of Verona, Virginia, about 9 miles (14 km) from Staunton. The majority of the dam was to be earthfill, with a 97-foot (30 m) high concrete gravity overflow section impounding a 4,750-acre (1,920 ha) 143,000-acre-foot (0.176 km 3 ) reservoir.
The lower reservoir dam on Back Creek is 135 feet (41 m) high and 2,400 feet (730 m) in length. It has a structural volume of 4,000,000 cubic yards (3,100,000 m 3 ) and creates a reservoir with a surface area of 555 acres (225 ha) and storage capacity of 27,927 acre-feet (34,447,000 m 3 ).
