How does the proposal to build a weir link with the proposal to introduce sea water into the Lower Lakes?
The temporary weir may be needed to protect South Australia’s water supply from declining water levels and potential threats such as acidic and salty water moving upstream from the Lower Lakes. These threats are caused by acid sulfate soils, naturally high salinity due to evaporation and low flows of fresh water entering the lakes. If the proposal to allow sea water into the Lower Lakes goes ahead then a temporary weir would need to be built to prevent salty water from moving upstream towards South Australia’s drinking water supply.
