Lake Argyle – it is impossible to understand the scale of this body of water created by damming the Ord River. This area would flood in the wet season and then be too dry in the dry season. The plains around it are fertile but needed a consistent supply of water. Lake Argyle and Lake Kununurra were created to create fertile agricultural plains. It is possible to swim in Lake Argyle as there are only (the more timid) freshwater crocodiles in residence.
