Phenomenal colour change for famous NZ lake

A massive landslip has changed the face of one of New Zealand's most famous lakes.

The stunning Lake Wakatipu - New Zealand’s longest lake - has changed from a deep blue to a mesmerising turquoise hue that's most obvious when viewed from above.

The astonishing change was first noticed after a landslip occurred in the nearby Dart Valley. Glacial rock and fine glacial silt or "flour" travelled down the face of the slip and into the lake where it is suspended in water, creating the magical colour by reflecting the light.

Distinct colour change

The colour change is so distinct, visitors may even catch sight of where the old and the new lake colours meet. Queenstown skydiving company NZONE managed to get a bird's eye view of the spectacular colour change, and photographed the phenomenal pattern emerging in the lake from 15,000 ft above Queenstown.

It’s unclear how long this extraordinary change will last but GNS (New Zealand's earth, geoscience and isotope research centre) principal scientist Simon Cox doesn’t believe the colour will be permanent because the glacial flour will eventually sink to the bottom.

"The lake is really big, you've got a huge amount to get scattered ... I suspect the [landslip] is not big enough to sustain that amount of material in the water over a long period of time," Simon Cox said.

"You might have something like that temporarily, but I would be very surprised if it was permanent, so perhaps enjoy it while you can."

Background Queenstown, New Zealand

Queenstown - on the shores of pristine Lake Wakatipu and surrounded by mountains - is New Zealand’s #1 adventure destination, renowned for adrenalin thrills, spectacular scenery and luxury style. The alpine resort town, in the southern South Island, is a lively year-round tourist destination with many visitor experiences.
