Chief refuge value

A wetland providing breeding habitat and a major drought refuge for waterbirds.

General description

The wetland comprises the terminal drainage basin of the Narran River, a distributary of the Balonne River, north-west of Walgett. It consists of gilgai overflow swamps through which flows the Narran to terminate in the Lake. Vegetation consists of dense lignum Muehlenbeckia cunninghamii and river cooba Acacia stenophylla. Flooding induces a large influx of waterbirds; in addition, the Lake provides drought refuge for birds when other areas of the inland are dry1, 2, 3.
