The Blue Lake – Mount Gambier
Due to calcite precipitation when the lake warms during the summer – the lake is a deep blue.

Photo shows the floor of this crater was filled by a shallow lake that had a ‘leg of mutton’ shape. With falling water table levels over the last century, the original lake has disappeared. This has occurred to a number of small crater lakes in the area.
