Following is a list of dams and reservoirs in Arizona. All major dams are linked below. The National Inventory of Dams defines any "major dam" as being 50 feet (15 m) tall with a storage capacity of at least 5,000 acre-feet (6,200,000 m 3 ), or of any height with a storage capacity of 25,000 acre-feet (31,000,000 m 3 ).
The construction of Vaal Dam started during the depression of the early thirties and the dam was completed in 1938 with a wall height of 54.2 metres (178 ft) above lowest foundation and a full supply capacity of 994,000,000 cubic metres (3.51 × 10 10 cu ft). The dam is a concrete gravity structure with an earthfill section on the right flank.
The Woodstock Dam and Driel Barrage are used to supply this additional water to Kilburn Dam when required. The scheme provides for up to 27.6 gigawatt-hours (99 TJ) of electricity storage in the form of 27,000,000 cubic metres (950,000,000 cu ft) of water.
The Vaal River Barrage Reservoir is a dam on the Vaal River near Vanderbijlpark, border Gauteng and Free State, South Africa. The Barrage, created by a set of gates across the Vaal River, was built by Rand Water downstream of the Vaal Dam, in 1923. The reservoir is 64 kilometres long and has a total storage capacity of 63 million litres, a ...
The Painted Rock Dam was constructed during a 3-year period from 1957–1960 by the United States Army Corps of Engineers to help control seasonal floods on the lower reaches of the Gila River. The river had no significant impediments between the Colorado River and the Coolidge Dam hundreds of miles upstream.
[4]: 56 More water was still required and by 1937 the Vaal Dam was completed 80 km south-east of Johannesburg. [1]: 217 [2] The next major project was the Lesotho Highlands Water Project in 1998 that saw the construction of several large dams and pipeline transporting water from Lesotho to the Vaal Dam in South Africa.

The As delivers water to the Saulspoort Dam and the Liebenbergsvlei and Wilge Rivers downstream, where after the water enters the Vaal Dam. The Vaal Dam can also be augmented from the Tugela-Vaal Water Project, by releasing water from the Sterkfontein Dam via the Nuwejaarspruit and Wilge River.
Theodore Roosevelt Dam is a dam on the Salt River located northeast of Phoenix, Arizona. The dam is 357 feet (109 m) high and forms Theodore Roosevelt Lake as it impounds the Salt River. Built between 1905 and 1911, the dam was renovated and expanded in 1989–1996.
