[6] Argyle mine was previously situated here from 1985 until November 2020 following several years of discoveries and yielded 865 million carats of diamonds.
[7] Ord River Dam post office opened on 1 March 1969 and closed on 15 November 1971 demonstrating the approximate duration of the construction camp.
[citation needed] Lake Argyle's usual storage volume is 5,797 gigalitres (2.047×1011 cu ft),[12] making it the largest reservoir in Australia.
At maximum flood level, Lake Argyle would hold 35,000 gigalitres (1.2×1012 cu ft) of water and cover a surface area of 2,072 square kilometres (800 sq mi).
[16] Cane toads reached the dam in late 2008, mostly via traveling along the Victoria Highway, with numbers rising significantly during the 2009 summer.
Birds for which the lake has global importance include magpie geese, wandering whistling-ducks, green pygmy-geese, Pacific black ducks, hardheads, black-necked storks, white-headed stilts, red-capped plovers, Oriental plovers, black-fronted dotterels, long-toed stints and sharp-tailed sandpipers.
[17] Common larger-bodied bird species found at the lake include the Australian pelican, black swan, eastern great egret, royal spoonbill, osprey and wedge-tailed eagle.
[17] Some threats identified by the IBA include invasive weed and animal species, such as the cane toad, as well as agricultural uses, free range cattle and feral ungulates that may be over-grazing in the shallow areas around the lake.
The IBA recommends that a fence be installed in the important shallows in the south and east to prevent all ungulates from entering those lake areas.
