This lake has world's clearest water!

Imagine diving deep down a lake, as deep as 80 mts, only to find crystal-clear visibility! Yes, a dive down this lake is as good as the visibility that ones gets with distilled water (80 mts). Here, we take you to the Blue Lake, set in New Zealand's South Island. Researchers were more than just surprised to discover such stark visibility at the Blue Lake, which is now pegged as the lake with the world's clearest water lake. Back in 2011, the National Institute of Water and Atmospheric Research (NIWA) conducted a study, and found that the lake water here has extreme visual clarity.

So, a dive down the Blue Lake would be a haven for watersports lovers and those who love the marine world. Of course, travellers are barred from diving down the river to maintain the sanctity of the place. Moreover, the lake is much revered by the Maoris and holds immense spiritual significance for them.

The lake is set inside a conservation area and entering the same s restricted. So much so that swimming in the lake is also banned to protect the ecosystem here. It falls under the purview of New Zealand's Department of Conservation. The stunningly clear lake is fed by water from another lake that is set above it. The Blue Lake is nicely perched at an altitude of 1,200 mts above the sea level. Research suggest that the already clear water of the lake above is further filtered by glacial debris, clearing it further. Moreover, it is estimated that the lake water is replaced every 24 hours, fed by water from the other lake.
What sets the place apart from others is that the place is also sacred to the local Maori tribe, Ngati Apa, and is thus fiercely protected. This is one of the main tribes in New Zealand's Rangitikei tribe. Maoris call it by the name of Rotomairewhenua (the Lake of Peaceful Lands); Ngāti Apa tīpuna and was an important part of the interwoven trail and was used as a marker.

Maoris also believe that the Blue Lake is fed by a river named Rotopōhueroa, which runs under the ground. They believe that the lake is a testament to nature's interconnectedness, and has lessons for the world. Well, we could not agree more. Of course, it's also one of the less famous, offbeat wonders of the natural world.
