Lake Argyle, Australia
An immense man-made reservoir in the remote East Kimberley, Australia, Lake Argyle has transformed the surrounding landscape, creating a beautiful marine environment and refuge for local fauna.
The traditional Aboriginal owners of the lands around what is now Lake Argyle are the Miriwoong Gajerrong peoples, who called the Ord River Goonoonoorrang. European settlers first came to the region in the late 19th century, following an 1879 report by Alexander Forrest, claiming that he had found over 10 million hectares of fertile land around the Ord River, near the Northern Territory border. Cattlemen and graziers from the east trekked to the new region, establishing the cattle empires of the Kimberley.
The land proved to be harsher than in Forrest’s report. While in the wet season, the lower reaches of the Ord River supported fertile lands, in the dry, the river would reduce to a series of waterholes. Without some way to harness the waters of the wet season, there was no way that the region could support an agricultural industry.
In 1959, the Australian Government gave permission and a grant to dam the Ord River. The Ord River Irrigation Scheme, led by the Western Australia government, began work soon after. A spot on the river, about 80 km from the Kimberley coast, was chosen to be flooded. The project saw the region transformed, as the town of Kununurra was established as a residence and service centre for the thousands of workers who contributed to the project. Controversially, the local Miriwoong Aboriginal people were not consulted about the project.
The Ord River Dam (or Lake Argyle) was completed in 1972. It is the second-largest man-made reservoir (by volume) in Australia, after Lake Gordon in Tasmania, and holds 32 million cubic metres of water (about twenty times the size of Sydney Harbour!).
In 1996, Lake Argyle became a source of hydroelectricity for the Kimberley region, a clean and renewable source of energy.
Since the completion of the project, Lake Argyle has developed an incredible and intricate eco-system. The Ord River pools had been home to small populations of freshwater crocodiles (or as the locals call them, ‘freshies’). Since the development of Lake Argyle, this has risen to a population of over 35, 000 freshwater crocodiles. While freshies are mostly harmless, occasionally a rather more fearsome saltwater crocodile (or ‘saltie’) can be found lurking! The lake is also home to several forms of fish – including barramundi, southern saratoga, archer fish, forktail cat fish, mouth almighty, long tom, bony bream and sleepy cod.
The Lake Argyle region, including surrounding mudflats and grasslands, has been declared by BirdLife International as an ‘Important Bird Area’. It is home to over 240 species of birds – almost 1/3 of Australia’s known species. Birds found in the region include magpie geese, Australian bustards, wandering whistling-ducks, Australian pelicans, black swans, egrets, and wedge-tailed eagles.
An easy day tour at about 40 minutes drive from Kununurra, Lake Argyle can be explored via lake cruise, scenic flight, or walking trail.
