Lakes are some of the most interesting naturally existing terrestrial elements on Earth. The reason for this is that lakes are usually formed by a sequence of unique events. In our last post, we spoke about Reelfoot Lake in North America which was formed by a series of earthquakes that occurred in the 19th century.

The formation of Reelfoot Lake was a result of existing rivers being blocked or diverted and a portion of land sinking so the diverted water settled in the new area and formed a lake. However, there are other even stranger lakes in the world. For instance, did you know that there is a lake in Australia that is literally baby pink in colour? How is this even possible? We have the answer for you.

What Is the Baby Pink Lake in Australia Like?

Off the southern coast of Australia, there is the Recherche Archipelago. Archipelagos are groups of islands or smaller land masses clustered in a group. In the middle of the biggest island in the Recherche Archipelago, there is a lake known as Lake Hillier.

This lake, quite simply, is baby pink in colour! If you fly over the lake, you’ll see a bubblegum pink coloured body of water landlocked on all sides. The lake is extraordinary because pink lakes are fairly rare in nature. The lake is surrounded by a thin strip of salt-rich beach and heavy forests.

Why is this lake pink in colour? Is it an effect of lighting? Is there another reason? Well, no one really knows, but everyone seems to speculate.

Why Is Lake Hillier Pink in Colour?

There is no definitive explanation for the colour of this lake because the area is kept pristine by the government of Australia. However, that hasn’t stopped scientists from speculating about the reasons for its colour. It is accepted that the colouration of the lake isn’t a trick of light because if you take the water in a jar, it remains pink.

The most widely accepted reason for the colour of this lake is a combination of three things. The first is the high salinity of this lake, the second is a specific type of bacteria in it, and the third is a specific type of algae in it. The explanation is that when the conditions are right, the algae and the bacteria produce dyes which mix to give the lake its unique pink colour.

Coloured lakes are rare on our planet, but that doesn’t mean that they don’t exist. There are a few in different locations all over the planet. One of the most popular pink lakes, Lake Retba, is in Senegal. It is regularly used by locals for harvesting salt. There is another pink lake known as Salt Pans of Torrevieja in Spain, and one in Canada known as Dusty Rose Lake.

Similarly, Peyto Lake in Canada is turquoise in colour, Emerald Lakes in New Zealand are emerald green in colour, Laguna Colorada in Bolivia is red and Hells in Beppu in Japan is a cluster of lakes with each lake having a different colour.
