Acid Sulphate Soils in the Lower Murray system.

One of the major reasons for the concern by people along the lower reaches of the Murray and the Lower Lakes is the build up of acid sulphate soil.

All of the wetlands around the Lower Lakes have been adversely impacted by falling water levels and increasing salinity in the lake water bodies.  Acid sulphate soils are a serious threat in many areas of the Lower Lakes and urgent action is required. The areas in question are either already dry, or will become completely dry and cut-off from the main body of Lake Alexandrina as the water level continues to fall over the coming months.

Recent CSIRO field surveys have confirmed that large areas of the shallow wetlands along the Goolwa Channel and in the lower reaches of Currency Creek and Finniss River have already acidified. It is  very important to protect the wetlands of the Goolwa Channel, Finniss River, and Currency Creek from acid sulphate soils.  These are important and highly valued fresh water biodiversity areas of the Lower Lakes.
