Burrinjuck Dam is a major gated concrete-walled gravity dam with three spillways across the Murrumbidgee River located in the South West Slopes region of New South Wales, Australia. The dam's purpose includes flood mitigation, hydro-power, irrigation, water supply and conservation. The impounded reservoir is called Lake Burrinjuck.
Commenced in 1907, completed in 1928, and upgraded in 1957 and 1994, the Burrinjuck Dam is a major ungated dam, located approximately 60 kilometres (37 mi) south-west of Yass. The dam was built by the New South Wales Water, Conservation & Irrigation Commission and the NSW Department of Public Works for town water supplies, river flows and domestic requirements, irrigated agriculture, industry, flood mitigation and environmental flows. The Yass and Goodradigbee rivers also flow into the dam. Together with releases from Blowering Dam, on the Tumut River, Burrinjuck Dam also provides a regulated flow of water for the Coleambally and Murrumbidgee Irrigation Areas. The dam divides the upper and lower catchment of the Murrumbidgee River and is the headwater storage for the Murrumbidgee Irrigation Area.
The dam wall constructed with 394 cubic metres (13,900 cu ft) of concrete is 91 metres (299 ft) high and 233 metres (764 ft) long. The maximum water depth is 61 metres (200 ft) and at 100% capacity the dam wall holds back 1,028,000 megalitres (36,300×106 cu ft) of water at 361 metres (1,184 ft) AHD. The surface area of the Lake Burrinjuck Reservoir is 5,500 hectares (14,000 acres) and the catchment area is 12,953 square kilometres (5,001 sq mi). The three sector gates plus two side channel spillways are capable of discharging 29,100 cubic metres per second (1,030,000 cu ft/s).
