Specifications

The Bartlett dam consists of 10 arches, 9 buttresses, and is flanked by 2 gravity wing dams. Before being modified, the Bartlett Dam was 287 ft (87 m) tall and contained 182,000 cu yd (139,000 m3) of concrete. After the mid-1990s modification, the dam is 308.5 ft (94.0 m) tall, made of 223,773 cu yd (171,087 m3) of concrete, and has a length of 823 ft (251 m). The width of the dam arch's ranges from 7.5 ft (2.3 m) at its base and 4.5 ft (1.4 m) at its crest. The reservoir created by the dam, Bartlett Lake, has a 178,186 acre feet (219,789,000 m3) capacity at the normal surface water elevation of 1,798 ft (548 m). It drains an area of 6,160 sq mi (16,000 km2) and has a surface area of 2,700 acres (11 km2). The dam's outlet works have a discharge capacity of 2,400 cu ft/s (68 m3/s). When the reservoir is at the maximum water elevation of 1,821 ft (555 m), the service spillway has a 287,500 cu ft/s (8,140 m3/s) capacity while the auxiliary spillway can discharge up to 261,700 cu ft/s (7,410 m3/s).
