Goulburn River channel, creating "The Barmah Choke" and "The Narrows" (where the river channel is unusually narrow), before entering into the proper Murray River channel again.
This complex series of events however divert attention from the primary result of the Cadell Fault. The primary result of the Cadell Fault is that the west-flowing water of the Murray River strikes the north-south running fault and diverts both north and south around the fault in the two main channels (Edward and ancestral Goulburn) as well as a fan of small streams, and regularly floods a large amount of low-lying country in the area. These conditions are perfect for River Red Gums, which rapidly formed forests in the area. Thus the displacement of the Cadell Fault 25,000 BP lead directly to the formation of the famous Barmah River Red Gum Forests
The Barmah Choke and The Narrows mean the amount of water that can travel down this part of the Murray River is restricted. In times of flood and high irrigation flows the majority of the water, in addition to flooding the Red Gum forests, actually travels through the Edward River channel. The Murray River has not had enough flow power to naturally enlarge The Barmah Choke and The Narrows to increase the amount of water they can carry.
The town of Barmah, Victoria is unusual in that it is north of part of New South Wales, although everywhere else Victoria is south of New South Wales. Echuca on the map above is very close to Barmah.
The Cadell Fault is quite noticeable as a continuous, low, earthen embankment as one drives into Barmah from the west, although to the untrained eye it may appear man-made.
Burra Creek
The Burra Creek (also known as the Worlds End Creek), which flows through Burra township, was once part of the ancient Murray River system. The system used to cross the Northern Mount Lofty Ranges through the Burra creek gorge, and then flow out to Spencer Gulf near Port Pirie. The Murray
