Lake
Pukaki is the second-largest of three roughly parallel alpine lakes running
north-south along the northern edge of the Mackenzie Basin (the others are
Lakes Tekapo and Ohau). All three lakes were created by receding glaciers
blocking their respective valleys with their terminal moraine. The glacial
feed to the lakes gives them a distinctive blue colour, created by glacial
flour (extremely finely ground rock particles from the glaciers). It covers
an area of 80 km², and is at an altitude of 480 metres above sea level.
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. Good views of the mountain, 70 kilometres to the north, can be had from the southern shore of the lake.
