Lake Tuggeranong, Reservoir in Tuggeranong, Canberra, Australia

Lake Tuggeranong is a reservoir formed by the Tuggeranong Dam, an earth-fill embankment dam across Tuggeranong Creek in the Tuggeranong district of Canberra. Completed in 1988 by Leighton Contractors, the dam wall is 20 metres high and 640 metres long. The lake covers 60 hectares and holds up to 1,800 megalitres when full.

The lake was built in 1987 to manage water from the nearby creek and stormwater systems as part of urban planning to make suburbs more liveable and reduce flooding. Its creation reflected Canberra's infrastructure efforts to integrate water management with community development.

Lake Tuggeranong is named after Tuggeranong Creek, from which it draws its water. The lake sits on land traditionally belonging to the Ngunnawal people, whose presence remains part of the area's identity.

A cycling and walking path about 6.7 kilometers long circles the entire lake, providing a straightforward way to enjoy the surroundings. Check water conditions before visiting, as algae toxins can develop during warm weather and make swimming unsafe.

The dam wall, finished in 1988 by Leighton Contractors, is 20 metres high and 640 metres long. Its uncontrolled spillway can pass 990 cubic metres per second. Upstream lies Isabella Pond, part of the same sediment-control chain.
