The Site comprises a permanent saline lake and part of a downstream system of inter-connected lakes and swamps of various sizes which are intermittently inundated. Rocky outcrops in the lake provide important moulting sites for internationally significant numbers of Australian shelduck (Tadorna tadornoides). The lake is also a refuge for resident and migratory waterbird species during drought conditions. It is used for science-based education and recreational activities such as bird watching.
