Location and Geography

Lake Retba (Lac Rose) is a beautiful saltwater lake with a surface area of around three-square kilometres, located on the picturesque Cap Vert Peninsula just outside of the busy city of Dakar.

The pink hues of the waters are created by these microscopic creatures, which grow in the severe salinity and produce a reddish pigment that mesmerises everyone who sees it.

The pink hue is especially noticeable during the dry season when additional salt and algae are left behind when the water evaporates. The lake is illuminated in a variety of pink shades, from soft pastels to rich rose hues, as the sunlight reflects off the water.

The Dunaliella salina algae and halophilic bacteria, on the other hand, have adjusted to these circumstances and are now thriving in the salty lake waters.

The pink colour of Lake Retba is maintained in large part by the microorganisms that live there. The carotenoids, which are pigments that give the pinkish red colour its origin, are produced by photosynthetic organisms called Dunaliella salina algae. These algae can grow where other living forms struggle to live because they have developed the ability to handle the high levels of salt and strong sunlight.

On the other hand, the halophilic bacteria support the lake’s entire ecosystem. They contribute in the cycling of nutrients and help in the breakdown of organic substances. The environment of Lake Retba is delicately balanced by these unique microorganisms living in peace.
