Yes, it’s really pink. All the time. No, Dr. Seuss didn’t fill it with pink ink, although that was the first thing that came to mind. This is one of many pink lakes, ponds, and lagoons in Australia, and there are actually quite a few pink lakes found around the world. Many of them can blame the color on an algae known as Dunaliella salina, which uses a reddish pigment for photosynthesis. Or they may be infested with Halobacteria, which also gives a pink hue. Yet another way a lake can turn pink is due to minerals in the surrounding rock that dissolve in the water, such as salt. You can see a roundup of pink lakes from all over at Scribol.
