❓ why
Why do some lakes look turquoise or milky blue?
Quick Answer
Tiny suspended particles, dissolved minerals, and light scattering can make lake water appear turquoise or milky blue.
The Full Story
Some lakes contain very fine rock flour from glaciers or suspended minerals from springs and surrounding rock. These particles scatter shorter wavelengths of light more strongly, giving the water a bright blue or turquoise look. In other lakes, dissolved limestone and low levels of organic material contribute to the color. The effect is most striking in clear water under strong sunlight. Famous examples include glacier-fed lakes in the Canadian Rockies and the Alps.
