It's not every day you see a body of water quite like this. And chances are, you had the same reaction we did: What the hell is going on? Chemical spill? Toxic dumping? A sign of the apocalypse?
If you picked 'D - none of the above', you'd be right. Truth is, this actually happens every year and it's completely natural. The lake is in the Camargue region along the Mediterranean coast of France.
The lake is naturally high in salt content, especially before harvest time. It's also home to brine shrimp and saline algae. Apparently, around this time of year, the shrimp die off and the algae really flourishes. That creates higher levels of salt, which turns the water red. The Daily Mail compiled some shots of the bizarre scene taken by photographer, Sam Dobson, from Moscow, Russia.
And this part of France isn't alone. Last year, this same kind of thing made a lake in West Africa look like strawberry milk. You can check out those photos here.
