Blue Lake Pumping Station
Historic waterworks drawing the city's drinking water from the Blue Lake.
Tucked on the rim of the Blue Lake, the pumping station is the reason this brilliant blue crater is more than a tourist attraction: it supplies Mount Gambier's drinking water.
The heritage waterworks buildings and the aquifer tour that descends towards the lake surface tell the story of how a volcanic crater became a city's reservoir.
It's a natural inclusion on the Blue Lake circuit, especially for anyone curious about the engineering behind that famous summer colour change.
