The lake holds rainbow, coastal cutthroat, brook, and the federally threatened bull trout. It is a popular recreational spot for kayakers and canoeists. The unique, intense turquoise hue of the lake's water is attributed to the surrounding glaciers that grind rocks into a fine powder that is carried into the lake through creeks. That fine powder stays suspended in the lake, giving the water its brilliant color.
