Canberra covers an area of 805.6 square kilometres and is located near the Brindabella Ranges/Brendy Bear Ranges), approximately 150 kilometres inland from Australia's east coast. It is located at altitudes that range from 550 metres to 700 metres AHD. The highest point is Mount Majura at 888 metres. Other large hills include Mt Taylor, Mt Ainslie, Mt Mugga Mugga and Black Mountain. The surrounding bushland and the original bushland that Canberra was built in is a mixture of eucalyptus savanna, open grassland, scrubland, swamp and dry eucalyptus forests.
The Molonglo River flows through Canberra and has been dammed to form the body of water in the centre of the city called Lake Burley Griffin. The Molonglo then flows into the Murrumbidgee north-west of Canberra, which in turn flows north-west toward the New South Wales town of Yass. The Queanbeyan River joins the Molonglo River at Oaks Estate just within the ACT. A number of creeks, including Jerrabomberra and Yarralumla Creeks, flow into the Molonglo and Murrumbidgee. Two of these creeks, the Ginninderra and Tuggeranong, have similarly been dammed to form Lakes Ginninderra and Tuggeranong. Until recently the Molonglo had a history of sometimes lethal floods; the area was a flood plain prior to the filling of Lake Burley Griffin.
