From the photographer:
This turqoise color is the actual color of the lake. It was taken around six o' clock in the morning, the only time (with the evening) that you can have a reflection in these lakes.
-Some explanation from Wikipedia for the color.
Rock flour consists of clay-sized particles of rock, generated by glacial erosion or by artificial grinding to a similar size. Because the material is very small, it is suspended in river water making the water appear cloudy. If the river flows into a glacial lake, the lake may appear turqoise in color as a result.
