Agriculture, formerly known as the Kimberley Research Station (KRS). KRS started in 1945 from the original Carlton Reach Research Station, set up by Kimberley Michael Durack with help from his brother William Aiden Durack in 1941, and support from the WA Department of Agriculture and the WA Public Works Department, being the first serious attempt at tropical agriculture on the banks of the Ord River. It was also in 1941 that (later Sir) Russell Dumas inspected the Ord gorges for dam sites on behalf of the Public Works Department.
The scheme involved damming the Ord River by building the Ord River diversion dam so that the waters could be conserved and directed to irrigate about 750 square kilometres (290 sq mi) of land. By 1966, there were 31 farms on the Ord River plains. In 1968 the second stage of the scheme was started with the building of the Ord River Dam (or Ord River Main Dam), known locally as "Top Dam," which holds back the waters of Lake Argyle.
Flooding of the Ord River continued until completion of the Main Ord River Dam situated 55 km upstream from Kununurra, which was started in 1968, and officially opened on 30 June 1972, with support from WA Premier John Tonkin, by then Prime Minister William McMahon, when he said "This marks the beginning of Ord Stage II (Two)." The Ord River Dam flooded the land of the Argyle Downs station, the home station of the pioneering Durack family, to form what has become known as Lake Argyle. Stone work from the original Argyle Downs homestead, was removed before Lake Argyle filled and was re-erected near the dam site to become the Argyle Downs Homestead Museum. The Museum had been run by Tourism WA but was taken on by the Kununurra Visitor Centre during 2010.
The second stage of the Ord Project still has not been fully developed but new work is underway. In May 2010, with major funding from the Federal Government, the extension of the main channel construction got underway under the Moonamang Joint
