The weir wall has reached the deepest part of the channel between Kumarangk (Hindmarsh Island) and Clayton Bay. It is a section that provides a refuge for fish in times of drought. The weir, that is supposed to be an ecological refuge, is destroying a refuge.

The mud wave extends hundreds of metres around the wall. The yellow “skirt” that was put in place, after a number of mishaps, was tethered to the ground but the rush of fresh water from the tributaries has ripped it free. The “Regulator” mud wave in now heading into Lake Alexandrina. The contractors are monitoring the situation.

The shore line is greening up. The new growth could be part of a fresh water recovery but if the gap is closed, this section will be cut off from the fresh water.
