Hunters Creek forms part of the Hindmarsh Island wetland complex and is a shallow freshwater channel which, when lake levels allow, feeds directly into Mundoo Channel and the Coorong creating estuarine conditions.
Previous surveys found that the creek contained a high diversity of native freshwater and estuarine fish species including species of state and national conservation significance such as Murray hardyhead, Yarra pygmy perch, Southern pygmy perch and congolli. The presence of these threatened native fish highlights the importance of this wetland for regional and national biodiversity.
In 2008 a fishway was constructed at the confluence of Hunters Creek and Mundoo Channel to enable fish movement between the two water bodies, however due to the drought and lack of water within Hunters Creek the fishway remained closed until the return of high flows to Lake Alexandrina and the subsequent rising water levels. Hunters Creek is now able to provide a connection between Lake Alexandrina and Mundoo Channel and estuarine species such as Congolli and Green back flounder have been observed using the Hunters Creek fishway. The camera has also documented a family of egrets who took up residence just outside the fishway.
