Blue Lake

A sizable monomictic crater lake called the Blue Lake is situated in a dormant volcanic maar that is a part of the Mount Gambier maar complex. One of four crater lakes on Mount Gambier Maar, the lake is located close to Mount Gambier in the Limestone Coast region of South Australia. Only two of the four lakes are still present, while the other two dried up as the water table plummeted over the past 30 to 40 years.

Though to have an average depth of 72 meters, Blue Lake can occasionally reach heights of 75 meters. The lake itself measures 1,087 by 657 m, while the crater rim is 1,200 by 824 m in size. The lake's surface lies 17 m below the level of the town's main street. The town receives its drinking water from Blue Lake.

The name of this body of water, which is close to Mount Gambier, comes from the water's vivid blue hue. Throughout the fall and winter, the water seems to turn a shade of grey. Residents in the neighborhood can take advantage of the lake's fresh drinking water harvest. On the edge of the lake is a tiny memorial to the well-known poet and politician Adam Lindsay Gordon.
