*************

Scrivener Dam, a concrete gravity dam that impounds Molonglo River, is located in Canberra, Australian Capital Territory, Australia. The dam creates Lake Burley Griffin, that was established for recreational and ornamental purposes. Named in honour of surveyor, Charles Scrivener, the dam was officially inaugurated on 20 September 1964 and the official filling of the lake commemorated on 17 October 1964, by the Prime Minister, Robert Menzies.

The dam wall is located on Lady Denman Drive and is adjacent to the National Zoo & Aquarium and a viewing area for the official residence of the Governor-General of Australia.

Scrivener Dam, designed in Germany,^[1] holds back the waters of the Molonglo River within Lake Burley Griffin. About 55,000 cubic metres (1,900,000 cu ft) of concrete was used in the construction of the dam wall. The dam is 33 metres (108 ft) high and 319 metres (1,047 ft) long with a maximum wall thickness of 19.7 metres (65 ft). The dam is designed to handle a once in 5,000 year flood event.^[2]

It utilised state-of-the-art post-tensioning techniques to cope with any problems or movements in the riverbed.^[3]

The dam has five bay spillways controlled by 30.5 metres (100 ft) wide,^[2]hydraulically operated fish-belly flap gates.^[3] Hinge anchors support the flap gates; with six hinges per gate, and four anchors per hinge.^[4] The fish-belly gates allow for a precise control of water level, reducing the dead area on the banks between high and low water levels. As at November 2010, the five gates have only been opened simultaneously once in the dam's history, during heavy flooding in 1976.^[2]

The dam wall provides a crossing for the lake and consists of a roadway, called Lady Denman Drive, and a bicycle path.^[5] The roadway was possible because the dam gates are closed by pushing up from below, unlike most previous designs that wherein the gates were lifted from above.^[6]
