The Stephens Creek Dam is an earth-filled embankment dam built on a rock foundation with an uncontrolled spillway across the Stephens Creek, located in the Far West region of New South Wales, Australia. The principal purpose of the dam is to supply potable water for the town of Broken Hill. The impounded 2,000-megalitre (71×10 6 cu ft) reservoir is called Stephens Creek Reservoir.
The dam was completed in 1892 by the Broken Hill Water Supply Company to provide a continuing water source for drought-ridden Broken Hill. The reservoir soon became inadequate and a further reservoir, Umberumberka, was built to add to the water supply. Stephens Creek Reservoir remains the primary water source for Broken Hill, a city of around 20,000 people and is a popular picnic area.[ citation needed ]
The height of the dam wall is 15 metres (49 ft), and 140 metres (460 ft) in length. The earth-filled embankment wall is 112×10 3 m3 (4.0×10 6 cu ft) by volume. The uncontrolled spillway discharges overflow at the rate of 900 cubic metres per second (32,000 cu ft/s). The reservoir has a maximum storage capacity of 2,000 megalitres (71×10 6 cu ft), over a surface area of 8.5 square kilometres (3.3 sq mi), and drawn from a catchment area of 510 square kilometres (200 sq mi).

The facility is owned and operated by Essential Energy, which, prior to 2004 was Australian Inland Energy and Water.

Fitzroy Falls Dam in New South Wales, Australia, is part of the Shoalhaven Scheme, completed in 1974. It consists of four separate earth and rockfill embankments located on the Yarrunga Creek upstream of Fitzroy Falls and about 16 kilometres (9.9 mi) southeast of Moss Vale. The main embankment of 760 cubic metres (27,000 cu ft) is 14 metres (46 ft) high and 1,530 metres (5,020 ft) in length. At 100% capacity, the dam wall holds back approximately 9,950 megalitres of water, creating the impounded Fitzroy Falls Reservoir, which has a surface area of 522 hectares, drawn from a catchment area of 31 square kilometres (12 sq mi). The spillway has a discharge capacity of 516 cubic metres per second (18,200 cu ft/s).
Wingecarribee Dam, completed in 1974 as part of the Shoalhaven Scheme, is an earth and rockfill embankment dam structure located on the Wingecarribee River about 15 kilometres (9.3 mi) southeast of Bowral in New South Wales, Australia. The embankment of 573 cubic metres (20,200 cu ft) is 19 metres (62 ft) high and 1,140 metres (3,740 ft) in length. At 100% capacity, the dam wall holds back approximately 25,875 megalitres and creates the impounded reservoir of Wingecarribee Reservoir that has a surface area of 625 hectares, drawn from a catchment area of 40 square kilometres (15 sq mi). The spillway has a discharge capacity of 520 cubic metres per second (18,000 cu ft/s). Wingecarribee Reservoir lost around 9,000 megalitres of storage capacity as a result of the inflow of peat from the Wingecarribee Swamp collapse in August 1998. The original storage capacity was 34,500 megalitres.
