[1] It is 115 metres (377 ft) high and is located about 12 kilometres (7.5 mi) south of Piggs Peak.

[3][5] In 1992, the eSwatini and South Africa governments signed a treaty covering the "design, construction, operation and maintenance" of the Driekoppies and Maguga Dams.

[3] The dam's primary purpose is irrigation (for water-intensive sugar cane, forestry and "about 1000 of Eswatini's small farmers"[6]) but a hydroelectric power station with a capacity of 20 MW (generated from two units, each with a capacity of 9.9 MW[7]) was to be completed in October 2006.

[5] It has been designed to withstand a probable maximum flood of 15,000 cubic metres per second (530,000 cu ft/s).

[12] The dam also won the Concrete Society of Southern Africa's 2003 Fulton Award for Civil Engineering Structures.
