In a pristine New Zealand national park, the Blue Nelson Lake – also known as Rotomairewhenua – holds the title of the world’s clearest lake. Scientific tests carried out in 2011 by New Zealand’s National Institute of Water and Atmospheric Research (NIWA) showed Blue Lake to be the clearest natural body of fresh water known to man.
According to the NIWA research results, visibility in the lake is up to 80 metres – meaning the water is considered almost as “optically clear” as distilled water. Be sure to check out the last photo, that will blow your mind!
