The Wimmera Catchment Management Authority conducts regular surveys of the platypus population in McKenzie creek just outside the Park. There has been a sharp decline in numbers, so there is to be an environmental water release from Lake Wartook to an 18km stretch of the river. “The authority has identified this stretch of the river as relatively healthy but fragile and crucial for maintaining a struggling ecosystem …The release strategy is designed to mimic a summer-autumn flow pattern and involves a 490 megalitre release from November until May.”
