An aerial operation is underway to protect a pump that supplies drinking water to almost 300 properties in South Australia, but some homes in the area have already been engulfed, after the main levee failed to hold back River Murray floodwaters.
The State Emergency Service (SES) said the secondary levee at Cowirra, near Mannum, had also been seriously eroded as the peak of the floodwaters approached mid-Murray towns a day sooner than expected.
