Light that hits the surface of the lake from straight above penetrates more deeply, reflecting less. When the lake is deep, and the angle of incoming light is smaller, Lake Michigan’s color appears deep blue. This is because the light travels down with little obstructions and dissipates far below the surface.

Why is Lake Michigan water so blue?
Blue water lakes
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. These short wavelengths scatter to create a deep blue color in clear lakes.
What makes Great lakes blue?
The blue in Lake Michigan and Lake Huron is sediment brought to the surface when strong winds churned the lakes. The green in Lake Erie and in Lake Huron’s Saginaw Bay is algae, which builds on the surface when winds are calm.
Why is Lake Michigan water green?
Cladophora – natural green algae
Because of Lake Michigan’s excellent water clarity, it has been observed growing underwater at depths of more than 30 feet. Wind and wave action cause the algae to break free from the lake bottom and wash up on shore.

The sky is blue because blue light is scattered more easily than the other colors of light. The surface of seas and lakes often reflect blue skylight, making the water appear more blue.

The story of Bellandur and Jakkur lakes
Throughout the year, Jakkur lake water is green in colour, reflecting uncontrolled growth of harmful algae also called harmful algal blooms (HABs).
What are lake Colours?
Lake Colours Defined
A lake color or lake pigment is basically insoluble in nature and colors through dispersion. Lakes are produced through precipitation of soluble dyes with some metallic salt. Thus, lake colors are manufactured with the help of FD&C dyes and can thus be easily mixed with fats, sugars and oils.
Why is Lake Michigan so dark?
The water of Lake Michigan is a lighter greenish color.It was called the Black River because the sediment and organic material in the river gave it a dark-color. The Great Lakes can get algae that can give the water a greenish hue (it’s safe, you can swim in it).

What is the dirtiest Great lake?
Water is blue because it absorbs red, yellow and green light, but scatters blue light.The reason a small amount of water appears clear is because not much light is scattered. In larger bodies of water there are more water molecules for light to collide with, resulting in more blue light being scattered.
Which Great lake is the deepest?
Of all of the Great Lakes, Lake Erie had become predominantly polluted by the 1960s, largely due to the heavy industrial presence along its shores. With 11.6 million people living in its basin, and with big cities and sprawling farmland dominating its watershed, Lake Erie is severely impacted by human activities.
