English: We are looking at the northern end of Wivenhoe Dam. Wivenhoe Dam consists of an earth and rock embankment 2.3 kilometres (1.4 mi) long and 50 metres (160 ft) high. It has a concrete spillway section on which five steel crest gates are installed. The gates, at 12 metres (39 ft) wide and 16.6 metres (54 ft) high, are among the largest of their type in the world. The dam also has an auxiliary spillway to stop over-topping. The dam's reservoir has a total storage capacity of 2.61 cubic kilometres (0.63 cu mi), of which 1.16 cubic kilometres (0.28 cu mi) is used for urban water storage. Its surface area is 109.4 square kilometres (42.2 sq mi) and it has a 462 kilometres (287 mi) shoreline. 200 properties were acquired to provide the 337.50 square kilometres (130.31 sq mi) of land required for the dam. The catchment area is approximately 7,020 square kilometres (2,710 sq mi) and has an average annual rainfall of 940 millimetres (37 in). The dam holds twice as much water as Sydney Harbour and is about seven times bigger than Hinze Dam at the Gold Coast and contributes to the Gold Coast's water supply - Day 2 Watts Bridge Airfield Festival of Flight 'The Vintage Experience' 2010.
