Lake Ginninderra

Lake Ginninderra is a lake in the Australian capital Canberra. It was created in 1974 to collect ² in a catchment area of ​​98 km excess rainfall during storms and to preserve the Molonglo River from flooding. Around the lake there are many neighborhoods in the boroughs Belconnen and Gungahlin. The lake is a habitat for many water birds, such as mourning swans, moorhens and ducks.

The 1.05 km ² and up to 3.5 m deep lake was created by the construction of the dam the road Ginninderra Drive, which leads across the creek Ginninderra Creek. In 2004 the dam was raised by 1 m in order to be prepared for a flood that can theoretically occur once every 1 million years. The point of this construction project is controversial because of Ginninderra Drive is almost 8 m above the lake level and even during the most violent storms in the formation of the Lake, this never increased by more than 30 cm.
