Turquoise Waters of Bow Lake

The turquoise waters of Bow Lake are one of its most captivating features, making it a must-visit destination in Banff National Park. This striking color is a hallmark of many glacial lakes in the Canadian Rockies, and Bow Lake is a prime example.

Why Are Bow Lake's Waters Turquoise?

Bow Lake's Glacial Flour

Bow Lake is fed by glacial meltwater, primarily from the Bow Glacier. As the glacier grinds against the bedrock, it creates a fine sediment known as glacial flour or rock flour. This sediment is carried into the lake by meltwater streams.

The glacial flour remains suspended in the lake's water, scattering sunlight. Shorter wavelengths of light (blue and green) are reflected back to our eyes, creating the lake's vibrant turquoise hue.

Seasonal Variations at Bow Lake

The intensity of the color can vary depending on the season, weather, and amount of sediment carried into the lake. Late spring and summer, when glacial melt is at its peak, are often when the lake appears most vivid.
