Lake Retba (or Lac Rose) is a lake in Senegal, in the Northwestern part of Africa. It's named for pink hues, which are caused by a bacteria in the water called cyanobacteria. The lake is also known for its high salt content (similar to the Dead Sea), allowing people to effortlessly float along the surface. Although the idea of floating in a pink lake is intriguing, I would definitely worry about the bacteria. I realize that there is bacteria in all bodies of water, however, this species is so dominant it changes that entire lake a different color! Geez!
Would you float around Lake Retba, even with all the cyanobacteria?
