The lower Murray wetlands span more than 700 kilometres of linear floodplain along the River Murray between Swan Hill and the South Australian border. This includes creeks, wetlands and floodplains that are ecologically important and reflect the natural character and attributes of the River Murray floodplain.
The regulation and diversion of River Murray flows has dramatically altered the hydrology of the lower Murray wetlands. River regulation has substantially reduced the frequency and duration of the high river flows that are needed to water billabongs and floodplains. This change to the water regime has caused a decline in the environmental values of floodplain wetland sites.
Environmental water can be delivered to some wetlands in the region through a combination of direct pumping from the River Murray and through use of irrigation supply infrastructure. All the wetlands can be managed independently of each other.
