Adelaide Coastal Waters
Name & Location of Priority Site

Adelaide Coastal Waters - The coastal waters west of Adelaide are part of Gulf St Vincent. Gulf St Vincent contains the water north to Port Wakefield, west to the shores of Yorke Peninsula and south to Cape Jervis.

Adealaide coastal waters

Values to be protected Adelaide's coastal waterways are areas of major ecological, commercial, cultural and recreational importance. Over 5000 hectares of seagrass have been lost with associated seabed instability, habitat loss and amenity.
Key risks & pressures Historically, a range of pollutants has been discharged to the waterways, although nutrients (nitrogen and phosphorus) are of most concern, being associated with the loss of seagrass and mangroves. Elevated nutrient levels are causing seasonal growths of macroalgae (sea lettuce) and toxic algal blooms such as 'red tides' (dinoflaggelate blooms).

Coorong (including Coorong and Lakes Alexandrina and Albert Ramsar wetland)
Name & Location of Priority Site

The Coorong - a 140 km long expanse of water, separated from the southern ocean by a narrow coastal dune barrier; The Murray Mouth - an extremely dynamic and constricted tidal inlet where the River Murray reaches the sea, and; The lower Lakes (Lakes Alexandrina and Albert) - adjacent to the Coorong by a system of barrages.


Map of the Coorong area
Values to be protected

The unique ecological and hydrological values of the Coorong and Lakes Alexandrina and Albert wetlands. The primary determinants of the ecological character are salinity, water regime, water levels, keystone aquatic plants, habitat availability, turbidity and sedimentation. The Coorong is an important breeding area for the Pelican, Crested Tern and Fairy Tern, and Lake Alexandrina for egrets, ibises, cormorants and the Rufous Night Heron (Nycticorax caledonicus).

Ecological Character Description & Management Plan 
Key risks & pressures Low flows as result of water diversion upstream and drought conditions are changing the hydrological and ecological character. The low water levels are leading to exposure of acid sulfate soils, increased salinity and loss of aquatic habitats. Decline of water quality of the lakes contribute to fish kills.
