Lake Dumbleyung

Lake Dumbleyung is a large ephemeral salt lake located just southwest of the town of Dumbleyung in Western Australia's Wheatbelt region, about 267 kilometres southeast of Perth. Notable as the site where Donald Campbell set the world water speed record in 1964, the lake is an important bird habitat and seasonal natural attraction. When holding water it supports waterbirds, and when dry its vast white salt bed and surrounding reserves offer scenic views.

Visitors can expect a vast, flat ephemeral salt lake set in open Wheatbelt farmland with a white salt crust when dry and shallow water after winter rains. The main visitor area is at Pussycat Hill on the northeastern shore, which provides an elevated lookout over the lake, interpretive signage, a memorial to Donald Campbell's 1964 record, picnic facilities and views across the lake bed and surrounding nature reserves. Birdlife, wildflowers in season, and the Bluebird replica in town are key features.

Lake Dumbleyung is internationally known as the venue where British speed ace Donald Campbell set the world water speed record of 444.71 km/h (276.33 mph) in his jet hydroplane Bluebird K7 on 31 December 1964. The lake has long been used by the local Noongar people and was later central to pastoral settlement and the development of the town of Dumbleyung from the early 1900s.

The lake is part of Noongar country and holds significance for Aboriginal heritage. For the local community it is a landmark and symbol of town identity, commemorated by the Bluebird replica, memorial and the Dumbleyung Bluebird Centre which celebrates the 1964 record achievement.
