The blue lake

My Dad is visiting me at the moment so I took him to see the Blue lake, I never get tired of looking at this beauty.

Some information about the blue lake in Mount Gambier, SA Australia.

Situated in one of three extinct volcanic craters, the Blue Lake exposes the crystal clear water that has filtered underground through the limestone, passing slowly beneath the city.

Each year in November the lake starts its colour change from winter steel blue to brilliant turquoise blue and then in March changes back to steel blue.

With average depths of 70 metres, the lake contains 36,000 million litres (ML). It is the source of water to the city 3,500 ML is pumped annually from the lake into holding tanks which gravity feed water to the city and surrounds. No swimming or diving is permitted.
