Blue Lake Reservoir

Blue Lake Reservoir

The Blue Lake at Mount Gambier in the state's South East is a volcanic crater that contains groundwater from local aquifer systems, and it’s the third largest water storage facility in South Australia.

Groundwater seeps into the crater through porous limestone to create a lake around 36,000 megalitres in size, and about 10 per cent of the capacity is used each year by our customers in the city of Mount Gambier. Groundwater recharges the lake.

We currently don't monitor this reservoir's volume.

Capacity: 36 gigalitres

Open to the public: Yes, via organised tours. There is access to adjoining council land offering a walking trail and other interpretative facilities.
