Table Rock Dam is 6423 feet long and consists of a concrete section 1602 feet long and two earth embankment sections having a length of 4821 feet. The dam rises 252 feet above the riverbed, contains 1,230,000 cubic yards of concrete and 3,320,000 cubic yards of embankment. Four 18 foot diameter penstocks convey water to four 50,000 kilowatt generating units in the powerhouse. The first two units were ready for generation of power in June 1959, and installation of units three and four was complete in August 1961.

Table Rock Lake provides a storage capacity of 3,462,000 acre-feet, of which 760,000 are for flood-control and 2,702,000 are for generation of power. The flood control storage is equivalent to a depth of 3.5 inches of water over the entire contributing drainage area above the dam, 4020 square miles. At the top of flood control pool the lake has a surface area of 52,300 acres and a shoreline of 857 miles. The full conservation pool covers an area of 43,100 acres and has a shoreline of 745 miles.

Table Rock Lake is being operated during flood periods in conjunction with other lakes in the basin to prevent damages along the White and lower Mississippi Rivers. Since May 1957 flood reduction in the White River has resulted from the combined effect of the Table Rock, Bull Shoals, and Norfork Lakes, with Beaver Lake effecting regulation since 1964.

A master plan for recreation purposes and land management for Table Rock Lake was prepared in cooperation with the National Park Service, Missouri Department of Conservation, US Fish and Wildlife Service, Arkansas Game and Fish Commission, US Public Health Service, Arkansas State Health Department, and the Division of Health of Missouri, in order, that the best use could be made of the lake area.

The Corps of Engineers has developed 14 parks around the lake and 9 of these include commercial boat dock concessions. Development and operation of the Table Rock State Park adjacent to the dam is managed and maintained by the State of Missouri, Department of Natural Resources. The US Forest Service operates and maintains Big Bay Park located near Shell Knob, Missouri. On 300 acres immediately below the dam, the Shepherd of the Hills Trout Hatchery has been placed in operation and launching facilities to the river have been provided. These facilities are operated and maintained by the State of Missouri, Department of Conservation.
