The Lakes Argyle and Kununurra Ramsar Site comprises an extensive system of artificial freshwater reservoirs, with their associated permanent wetlands, formed by damming the Ord River in the eastern part of the Kimberley region of northern Western Australia.

It flooded the Ord valley upstream towards the site of the Argyle Dam, creating Lake Kununurra and subsidiary wetlands such as Lily Creek Lagoon and the Packsaddle Swamps.

However, because water levels are stable in Lake Kununurra and its associated wetlands, they have developed densely vegetated margins, with aquatic plants fringed by bulrushes, grassland and savanna woodland.

Tree species found on the wetland margins include broad-leaved paperbark, Eucalyptus microtheca, river red gum, Nauclea orientalis, Sesbania formosa and Lophostemon grandiflorus.

Over 200 terrestrial and aquatic bird species have been recorded in the area, which also supports several kinds of microbats, the little red and black flying-foxes, rakali, and large numbers of freshwater crocodiles.
