Lake Burley Griffin, Canberra |
The lake is an ornamental body with a length of 11 kilometres (6.8 mi); at its widest, it measures 1.2 kilometres (0.75 mi). It has an average depth of 4 metres (13 ft) and a maximum depth of about 18 metres (59 ft) near the Scrivener Dam. Its flow is regulated by the 33-metre-tall (108 ft) Scrivener Dam, designed to handle floods that occur once in 5,000 years. In times of drought, water levels can be maintained through the release of water from Googong Dam, located on an upstream tributary of the Molonglo River. (Wikipedia)
