Despite two-thirds of the Earth being covered by water, finding very clear water that occurs naturally is a challenging task. New Zealand's Blue Lake fulfills this dream for those seeking such a phenomenon. This rare lake has the distinction of possessing the clearest water on earth. Even at a depth of 80 metres in Blue Lake, one can distinctly observe the views above. The light blue hue of the water is the reason behind the lake earning its name. This remarkable lake is situated in the South Island of New Zealand. A 2011 study conducted by the National Institute of Water and Atmospheric Research (NIWA) demonstrated the exceptional clarity of the water in Blue Lake and the absence of impurities.
Blue Lake is situated at an altitude of 1,200 metres above sea level. Water from melting snow flows into Blue Lake from a lake higher up, contributing to the enhanced clarity of the water. Additionally, the water in Blue Lake getting completely refreshed every 24 hours helps to earn this lake the distinction of having the clearest water on earth. Despite its clarity, visitors are not permitted to take a dip in this water body. The lake, renowned for having the clearest water on Earth, is off-limits to tourists due to its location in a specially protected area. Preserving the beauty of Blue Lake has been a driving factor behind this decision by the authorities.
Blue Lake also holds significance as a sacred place for the Maori tribe of New Zealand, who refer to it by the name the 'Lake of the Peaceful Land.' The Maori people believe that a sacred underground river brings such clear water to this lake. Viewing Blue Lake as an embodiment of the interconnectedness of nature, the Maori people’s respectful attitude toward the water body contributes to keeping Blue Lake as a wonder of the world.
