Warriner-Margaret Creeks catchments

The poorly studied south of the Arckaringa subregion contains numerous GAB springs that appear to be located on the floodplain, some of which may lie in the main channels (D Wohling pers. comm., 2013). Similarly to North Freeling Waterhole, these springs are most likely important refugia for local biota and would probably be inundated during high flow events. No quantitative information is available regarding the springs or watercourses and limited observational data indicates that during periods of no flow the spring-fed waterholes become hypersaline owing to evapoconcentration (L Sampson, pers. comm., 2013). This area has also been suggested as a potential groundwater recharge zone (see Section, although no data exist to confirm this.
