Lat./Long. 29°10’S / 119°30’E

Quality of refuge: Significant (2)

Area (km²): <10,000

Chief refuge value

Habitat for waterbird, particularly stilts.

General description

An intermittent salt lake south of Sandstone which fills about once every 10 years, after which the water persists for a little less than a year. There is samphire (Halosarcia spp.) around the Lake, and low open woodland (Eucalyptus striaticalyx) around the margins1.

Other significant species

The Lake is a major breeding area for banded stilts Cladorhynchus leucocephalus, perhaps the most important2. Numbers of nests approach 200,000, and breeding probably takes place once a decade on average. Other species also breed at the Lake1, 2.
