Gregory River Cross Vanes 2013
AFPS staff supervised the construction of Cross Vane erosion protection structures in the Gregory River near Proserpine in Central Queensland. The Cross Vanes were constructed immediately downstream of a small gauging weir to slow down and direct flows away from the banks in order to halt erosion. The structures were also used to enhance fish passage past the weir by helping with the backing up of water. The structures have successfully stabilised bank erosion along this reach of the river and have helped maintain fish passage past the weir.
