What makes a lake blue?
What makes a lake blue? Blue water lakes contain low concentrations of algae and other substances, resulting in high clarity and a deep blue color. Water molecules absorb longer, visible wavelengths (e.g. red light, 600-700 nm) while shorter, blue wavelengths (< 500 nm) pass deeper into the water column.

Why are Canadian lakes so blue?
As glacial meltwater carries sediments, it creates a suspension in the water, scattering light and causing it to appear blue. The combination of glacial milk and the reflective properties of the suspended rock flour particles results in lakes such as Lake Moraine and Lake Louise exibiting breathtaking shades of blue.
Is Lake Louise always turquoise?
To ensure warmer weather and an excellent chance to witness the most vivid turquoise water, the best time to visit Lake Louise is in July and August. That being said, the color never leaves, and you can witness the lake thawed until late October/early November when the lake freezes over.
What causes a lake to look turquoise?
Limestone is composed primarily of calcium carbonate (CaCO3) and is white in color. As the river breaks down this rock into tiny crystals, these crystals will get mixed up into the water. When sunlight hits the tiny crystals, it will reflect that beautiful blue color.
Why is Lake Erie so blue?
Cyanobacteria blooms (blue-green algae) are a frequent occurrence in the Great Lakes, particularly in Lake Erie, Green Bay, and Saginaw Bay. These blooms may cause fish kills and discolored or foul-smelling water, affecting both human and ecosystem health.
Do people dye lakes blue?
It is common to see dyed water in public and recreational establishments, such as golf courses, recreation parks, ornamental ponds and decorative fountains. Aquatic dyes add blue or blue-green color to the water to reduce sunlight penetration.
