context_page_description: 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.
context_section_description: The National Capital Authority, a statutory authority of the Australian Government, is responsible for the administration and oversight of Scrivener Dam, as the dam lies within the Designated Area, under the Australian Capital Territory (Planning and Land Management) Act, 1988 (Cth). The Authority manages external contractors to deliver services that are competitively tendered.
  A routine annual audit of the dam wall undertaken during 2011 revealed that the anchor bolts, which are part of the flap gate hinge mechanism, showed signs of corrosion. These bolts, of which there are 120 in total, are each 50 millimetres (2.0 in) in diameter and 2 metres (6 ft 7 in) long. It was anticipated that work would be completed by the end of 2013, and cost A$20m.
