The Ord River
By Marco Stojanovik
The mighty Ord River in the eastern Kimberley region of Western Australia is one of the country’s most significant waterways, home to spectacular scenery. Rising in the Albert Edward range, it flows in an easterly and northerly direction 650km. Its course runs around the edge of the Purnululu National Park, through Lake Argyle, along the western edge of Kununurra and on to the Cambridge Gulf, where it bends and curves through flat wetlands before opening out into the Timor Sea.
Two man-made barriers constructed as part of the Ord River Irrigation Scheme dam the river on its lower reaches, capturing the monsoonal water that falls backs up in the ranges during the wet season. The Diversion Dam, completed in 1963, created Lake Kununurra to channel water to farmland on Ivanhoe Plain. While the Ord River Dam was completed in 1972, creating Lake Argyle (Australia’s largest artificial lake) and bringing a reliable water supply to Packsaddle Plains.
Odyssey Traveller conducts a tour of the Ord River and Lake Argyle as part of our small group tour of Australia’s Kimberley. Our tours of mature and senior travellers for couples and solo travellers of up to 12 people leave at the best times to visit the Kimberley: the dry season, June to September, or at the end of the wet season in April and May when the landscape is lush and the gorges – Bell Gorge, Cathedral Gorge – and rivers – Ord River, Gibb River, Fitzroy River, and Tunnel Creek – all flow with water. This article explores the history of the Ord and its irrigation scheme to assist your tour.

Traditional Owners of the Ord River
The traditional owners of the Ord River and surrounding lands in the east Kimberley region are the Miriwoong and Gajerrong peoples. They have a continued habitation in Western Australia dating back roughly 60,000 years, since Aboriginal Australians arrived on the continent. The East Kimberley region could possibly even be one of the original points from which Aboriginal Australians arrived, with different theories proposing this site, as well as others in the Northern Territory as the most likely landing points from the islands of southeast Asia.
The Miriwoong and Gajerrong peoples used to live in harmony with the land stretching from Molly Spring in the west, to most of the grand Ord River including parts of Lake Argyle, and way beyond the Northern Territory border across Keep River National Park and up to the coast. Along the Ord River, places of ceremony created during their Dreaming sustained them during the dry season,
The wider Kimberley region showcases a rich cultural legacy of Aboriginal habitation. It is home to what is believed to be the world’s oldest examples of rock art, dating back at least 16,000 years. One example, the Gwion Gwion rock paintings, display distinctive spindly stick figures, ornamented with accessories such as bags, headdresses, and tassels.
Another major form of rock painting in the Kimberley are the Wandjina, believed by the local Mowanjum people to be the supreme creator, depicted with huge eyes but no mouth. The first Wandjina are believed to have been painted 4000 years ago, with the figures continuing to be painted today, making it the world’s oldest continuous sacred painting movement.
First European Contact: Alexander Forrest and the Duracks
The first European to discover the Ord River was Alexander Forrest in 1879 during his six-month expedition in the Kimberley region. He named the river after Sir Harry Ord, Governor of Western Australia (1877-80).
Forrest boasted of the Kimberley’s permanent water supply and grass in abundance, appearing to be the best pastoral proposition in Western Australia. His reports came at the right time, just as investors in in Melbourne and Brisbane were looking for new worlds to conquer in northern Australia. To capitalise on this interest, he set himself up as land agent for prospective investors, even though as a Survey Department official he was not expected to profit from his find.
When applications were invited for pastoral leases in the Kimberley district in October 1880, it attracted an immediate response. Over the next three years, applications were lodged for leaseholds totalling more than 20m hectares. Applicants included speculators vying for a piece of land with river frontages without ever actually setting eyes on the country, as well as members of Western Australia families who had established themselves in the south-west and were looking for opportunities for their younger generation.
One of the more significant applications for land were made by members of the Durack family and associates. Seeking land for their sons, Patrick ‘Patsy’ Durack and his brother Michael travelled from Queensland to Perth to meet Forrest. At Forrest’s home, some 2,500 km from the land of promise, the men pored over a map and selected just under 162,000 hectares of land along the banks of the Ord and more than 60,000 hectares around other rivers. Paying a fortune at the requisite of 10 shillings an acre, the Duracks became the leases of a number of station properties, including Argyle, Rosewood and Lissadell on the lower Ord.
The family could afford the payment as they were already vastly wealthy. They had emigrated from to New South Wales in 1853, escaping the harsh life of tenant farming in Ireland, made increasingly untenable by crippling land rent and potato blights. Here led by Patrick, they quickly accrued massive amounts of wealth, pioneering into apparently empty land for livestock. Having established successful business enterprises in New South Wales and then western Queensland, they turned their attention to the west.
In 1883, Patrick took on the immense challenge of droving 7,250 head of breeding cattle and 200 horses 4,828 km from Queensland to the Ord River . The longest overland trek any Australian cattle drovers had undertaken until that time, it took an incredible 2 years and 4 months to complete. But it was no easy feat. Financially, the Duracks had to fork out £72,000 ($11 million today), while also suffering the loss of several men and half the cattle.
In her biographical snapshot of her grandfather, Patrick, Mary Durack explains the impetus for such a trek as ‘land hunger’. Ian Hoskins adds that “probably avarice, entitlement and insecurity go some way to understanding the amazing quest… [and] there was, of course, the perennial ‘thirst’ for reliable water that accompanied most European quests for agricultural land in Australia.”
Indeed, pastoral settlers like the Duracks were attracted to the Kimberley but its splendid rivers, fine pastures, and reliable rainfall. Along the Ord River especially, these conditions would be exploited into the next century and beyond with the Ord River Irrigation Scheme.
Early Plans to Dam the Ord River
The new pastoral settlers quicky noticed that although there was extremely heavy rainfall on the Ord in the ‘wet’ seasons, during the ‘dry’ season it was reduced from a fast-flowing river to a series of waterholes. As such, aspirations soon turned to harnessing the waters of the wet seasons; irrigated pasture could save the precarious Kimberley cattle industry, and cropping might provide another source of wealth.
To do this, the Ord River would have to be dammed. By capturing much of the 2500 gigalitres of water that flowed into the ocean each day during the wet season storms, the semi-desert cattle country could be transformed into a luscious, year-round agricultural area.
It was Michael Patrick Durack – son of Patrick Durack – who first observed the agricultural potential for the region, as early as the 1920s. Then in the late 1930’s, during a drought in the region, his son Kimberley Michael (Kim), having recently completed a course in agricultural science, conducted experiments in irrigation and wrote a report on the possibility of harnessing water.
As a result, in 1941, the Western Australian government sent its State Director of Works, the experienced dam and irrigation engineer Russell Dumas, to survey the Ord River dam sites with Kim’s help. The following year, Kim was appointed manager of the Ord River Experimental Station to to carry out investigations into tropical agriculture.
The Kimberley Research Station was then established in 1945 by the Council for Scientific and Industrial Research (later CSIRO) and the Western Australian Department of Agriculture, as part of a plan to develop a national irrigation policy. The start here was modest compared to the Snowy Mountains Scheme, with inconclusive evidence into suitable crops and little work done on the economic viability of the project. Nevertheless, momentum was maintained, and interest continued.
Ord River Irrigation Scheme Stage One
Experimental farming continued at the Kimberley Research Station into the late 1950s, testing the viability of growing cash crops in the fertile tropical climate. This ultimately culminated in the Ord River Irrigation Scheme, with the goal of creating an Ord River Irrigation Area by damming and redirecting the flow of one of Australia’s fastest flowing rivers during the summer wet season.
In 1959 a grant from the Commonwealth Government was finally approved, and in 1960 the Western Australian Government committed to Stage One of the project – the Diversion Dam across the Ord River.
The Diversion Dam, completed in 1963 at a cost of £4 million, backed the river up sufficiently to create Lake Kununurra and feed irrigation canals across the Ivanhoe Plain – 14,000 hectares of land. Commercial cropping had begun.
Kununurra town was also built nearby at this time as the residential and service centre for the scheme. Its name was Westernised from the local Aboriginal name for the Ord River – ‘Cununnurra’, meaning ‘big waters’.
A larger dam – the Ord River Dam – was built in 1970-72, 40km south of Kununurra where the Ord River meets the Carr-Boyd Ranges, to support irrigation expansion. Its construction formed a major storage reservoir called Lake Argyle. One of the world’s largest man-made water bodies and the largest freshwater storage on mainland Australia, the lake has a capacity of 10 760 million cubic metres (equivalent to nearly 20 times the water volume of Sydney Harbour).
Water stored year-round in the enormous Lake Argyle not only supplies irrigation to sustain agriculture in dry periods but is also used for hydroelectric power generation, supplying renewable energy to the Argyle Village, Wyndham, Kununurra and the Argyle Diamond mine.
Stage One Commercial Crops
Initially, a number of commercial crops were planted on the newly established agricultural farmlands created by the two dams in Stage One, such as rice, cotton, sugar as well as some experimental crops. Cotton soon became the preferred crop for the area, with some 17,500 bales of Ord River cotton marketed between 1963 and 1973. However natural pests made growing the crop expensive, requiring the spraying of costly chemicals to curb insect attacks. Then the withdrawal of commonwealth subsidies made the already expensive crop unprofitable and it was abandoned.
Neither were other early products economically viable, causing some early farmers to leave the region. Tobacco failed due to an emerging negative community attitude towards smoking and tobacco use. Rice crops were regularly attacked and consumed by large numbers of native Australian magpie geese. Meanwhile, later research determined that other experimental crops were simply not suited to the soil types and the region’s specific environmental conditions.
By the 1980s, only ten percent of the possible irrigation area was under cultivation and the Ord River Irrigation Scheme had become Australia’s most costly and controversial irrigation project. Bananas, mangoes, and melons were the main crops during this time, grown to compete with Queensland and Northern Territory farmers ‘out of season’.
Sugar was then trialled again in the 1990s, making money before prices collapsed. With the end of sugar, chickpeas were planted out in broadacre fields fed by the long, straight canals full of Ord River water.
