The lakes receives intermittent flow from the Jerdacuttup River, and lie in a narrow band of remnant bush, four kilometres wide, along the coast, in a relatively natural state.
The larger of the two Jerdacuttup Lakes is in a Nature Reserve and is monitored for its contribution to waterbird conservation. It is semi-permanent and hypersaline, and has a broad area of wetland vegetation. The vegetation is very valuable as a waterbird habitat, supporting a large number of waterbirds, a moderate number of species and moderate breeding.
