SES worried about Echunga dam failing, as volunteers put in fourth pump to reduce water level

A dam wall in the Adelaide Hills town of Echunga is still at risk of collapsing and residents will have to spend at least another 24 hours away from their homes, the South Australian State Emergency Service (SES) says.

The SES said it was trying to reduce the level of water in the private dam by 1.5 metres to reduce pressure on the dam wall.
