This beautiful lake in Central Otago is famous for its unique and visually striking landscape.

Once renowned for its turquoise-blue hue, due to the lake's mineral-rich water (hence the name Blue Lake), the water's current colour more closely resembles the reflection of the sky.

History

The Blue Lake isn't just a pretty sight—it's steeped in fascinating history that stretches back thousands of years.

St Bathans, formerly known as Dunstan Creek, is a historic gold mining town, and this now peaceful lake was once bustling with the residents' extensive mining activity. 

As miners dug deeper into the earth in search of riches, they unintentionally unearthed a hidden geological marvel: layers upon layers of ancient sediment.

By 1933, the mining pit reached a depth of 168 meters, making it the deepest mining pit in the Southern Hemisphere. 

The lake sediments, some dating back millions of years, now lie undisturbed beneath the tranquil waters, preserving a record of the region's geological past.

Today, scientists study these lake sediment layers, piecing together clues about ancient climates, ecosystems, and even long-extinct species.
