Lake Pukaki

13km north of Twizel is Lake Pukaki, the second largest glacier lake in Canterbury region (81 sq.km). The mighty Tasman River, fed by meltwater from great glaciers, flows into the north end of the lake, which lies 500m above sea level. The lake's high content of rock flour (finely ground particles of rock held in the glacial meltwater) gives its water a milky turquoise color.
