Lake Pukaki – New Zealand

Lake Pukaki is the largest of three roughly parallel alpine lakes (with Lakes Tekapo and Ohau) running north-south along the northern edge of the Mackenzie Basin on New Zealand’s South Island. All three lakes were created when the terminal moraines of receding glaciers blocked their respective valleys, forming moraine-dammed lakes.
The glacial feed to the lakes gives them a distinctive blue colour, created by glacial flour, the extremely finely ground rock particles from the glaciers.
The lake is fed at its northern end by the braided Tasman River, which has its source in the Tasman and Hooker Glaciers, close to Aoraki/Mount Cook.
