The Lake Argyle Islands are a large group of islands in Lake Argyle, created by the Ord River Dam on the Ord River in the Kimberley region of Western Australia.
The islands are former elevated points and ranges found on what used to be a section of Argyle Downs Station, prior to the damming of the Ord River in 1971.
As the lake filled, the lower grasslands became submerged while higher places along ranges became islands.
Some islands have sandy beaches and a range of flora and fauna, while others are swampy, or rocky and barren.
However, most of the islands are permanent, because the water level is unlikely to significantly change.
