The width of the dam arch's ranges from 7.5 feet (2.3 m) at its base and 4.5 feet (1.4 m) at its crest.[7]
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 feet (548 m). It drains an area of 6,160 square miles (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 cubic feet per second (68 m3/s). When the reservoir is at the maximum water elevation of 1,821 feet (555 m), the service spillway has a 287,500 cubic feet per second (8,140 m3/s) capacity while the auxiliary spillway can discharge up to 261,700 cubic feet per second (7,410 m3/s).[8]
