Windamere Dam is a minor ungated rock fill with clay core embankment dam with an uncontrolled unlined rock cutting spillway across the Cudgegong River upstream of Mudgee in the Central Tablelands region of New South Wales, Australia. The dam's purpose includes hydro-power, irrigation, water supply, and conservation. The impounded reservoir is called Lake Windamere.
Commenced in 1974 and completed in 1984, the Windamere Dam is a minor ungated dam, located approximately 19 kilometres (12 mi) south-west of Rylstone. The dam was built by Abignano Pty Limited on behalf of the New South Wales Department of Land and Water Conservation to supply water for irrigation and potable water for the towns of Mudgee and Gulgong. Windamere Dam operates in conjunction with Burrendong Dam to supply water to the Cudgegong and Macquarie valleys.
The dam wall constructed with 1,740 cubic metres (61,000 cu ft) of rock fill with clay core is 67 metres (220 ft) high and 825 metres (2,707 ft) long. The maximum water depth is 58 metres (190 ft) and at 100% capacity the dam wall holds back 368,120 megalitres (13,000×106 cu ft) of water at 552 metres (1,811 ft) AHD. The surface area of Lake Windamere is 2,030 hectares (5,000 acres) and the catchment area is 1,070 square kilometres (410 sq mi). The uncontrolled unlined rock cut spillway is capable of discharging 6,270 cubic metres per second (221,000 cu ft/s).
