The Valley Lake’s Volcanic Origins

Nestled in the heart of South Australia’s Limestone Coast, Mount Gambier is a city renowned for its unique geological formations and picturesque lakes. Among these natural wonders, the Valley Lake holds a captivating story of volcanic origins.

The Valley Lake, along with the Blue Lake and Leg of Mutton Lake, forms part of a volcanic crater system that was created by a series of eruptions approximately 4,500 years ago. These eruptions spewed forth vast amounts of lava, which flowed over the surrounding landscape, creating a series of lava domes and cones.

As the lava cooled and solidified, it formed a hard, impermeable layer of rock known as basalt. This basalt layer acted as a barrier, preventing water from draining away from the crater. Over time, rainwater accumulated within the crater, forming the Valley Lake.

The Valley Lake is a maar lake, a type of volcanic lake that is formed when groundwater comes into contact with hot magma. The resulting steam explosion creates a crater, which is then filled with water. The Valley Lake is one of the largest maar lakes in Australia, with a surface area of approximately 1.5 square kilometers.

The lake’s water is highly alkaline, with a pH of around 10.5. This alkalinity is due to the presence of dissolved minerals, such as carbonates and bicarbonates, which have been leached from the surrounding volcanic rocks. The high alkalinity gives the lake its distinctive blue-green color.

The Valley Lake is a popular tourist destination, offering visitors the opportunity to explore its unique volcanic landscape. The lake is surrounded by a walking trail, which provides stunning views of the lake and the surrounding countryside. Visitors can also take a boat tour of the lake, which offers a closer look at its crystal-clear waters and abundant birdlife.
