This is only a small amount of water that does not flow into the Darling River because of the giant Levi banks that have been built to capture the water for growing cotton
The car is on the Levi bank. Note the height of the water
This shot of the Darling river is taken from the same position as the previous one only panning slightly to the right. Notice the difference in water levels. No wonder the Murray/Darling Basin is in such a mess down stream with this happening here.
