Narrung wetland is a small 31 hectare wetland located immediately west of the Narrung Narrows between Lake Alexandrina and Lake Albert. The wetland is typically shallow and ephemeral. When lake levels allow the wetland is connected by narrow channels to both Lake Alexandrina and Lake Albert.
The saline nature of Narrung results in vegetation dominated by samphire, although when inundated dense beds of Ruppia tuberosa and Myriophyllum caput-medusae are also found. Both these submerged aquatic plant species are important food sources for grazing waterbirds such as black swans and waterfowl.
The wetland was disconnected from both Lake Alexandrina and Albert during the recent drought, and as a result dried out completely. Environmental water was delivered to the wetland, through The Living Murray program, in 2009 to promote the growth of submerged aquatic plants.
As a result of the environmental watering, aquatic plant populations were sustained throughout the drought and are responding quickly to the water. Images from the Narrung wetland camera show large patches of submerged aquatic plants which have germinated.These plants provide important feeding and breeding opportunities for waterbirds and native fish. Murray hardyhead have been recorded within the wetland and may return and benefit from this improved habitat.
Narrung wetland is managed in consultation with the South Australian Murray-Darling Basin Natural Resources Management Board and the Coorong District Local Action Planning Association and the Goolwa to Wellington Local Action Planning Board. The dedicated Narrung community wetland group regularly conduct groundwater, surface water and photopoint monitoring, frog monitoring and actively participate in vegetation surveys. The group has also conducted numerous revegetation works around the wetland using seedlings grown from locally collected seed.
