For an Instagrammer, the bluer the water the better.
But in the pursuit of that fairy tale-esque selfie, one 'lake' in Siberia has grown in popularity for its unnatural turquoise waters - and that's just it. None of it is natural.

In reality, the lake is actually a chemical dump site for a nearby heating and electrical station managed by the Siberian Generating Company. It gets its hues from the coal ash dumped in the waters, which is full of calcium salts and other metals.
According to Buzzfeed, some have started calling it the 'Novosibirsk Maldives' and some really special ones even have pics of themselves in the water - despite many warnings from the coal company to stay out of the toxic water.
While they claim its radiation levels are normal and the water isn't poisonous, contact with skin can cause allergic reactions.
Another danger the lake poses is its ashy floor - it's extremely muddy and people can get stuck very quickly.
However, it still remains popular under the hashtag #????????? (which means 'ash dump'), with one couple even doing their wedding shoot in front of the lake.
