Why is Lake Michigan water green?
Cladophora is a green algae found naturally along the Great Lakes coastlines. It does not produce toxins the way blue-green algae can. It grows on submerged rocks, logs or other hard surfaces. Because of Lake Michigan’s excellent water clarity, it has been observed growing underwater at depths of more than 30 feet.
Is Lake Michigan water dirty?
The presence of E. coli in the water along Lake Michigan’s shoreline is a strong indication that the water was recently contaminated by sewage or animal fecal waste. These wastes may contain many types of harmful disease-causing organisms.

Why is Lake Michigan so blue?
Light and the Lake’s Color
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.
Is Lake Michigan safe to swim in?
Always use caution and never swim alone. A Moderate Swim Risk implies that breaking waves and currents are expected at the beach. Stay away from dangerous areas like piers, breakwalls, and river outlets at these times.
Why is Lake Michigan so polluted?
The largest source of pollution in the Great Lakes is phosphorous runoff from farmland. The nutrient feeds cyanobacteria. That’s a harmful algal bloom which can harbor a toxin that can make humans and animals sick.
How polluted is Lake Michigan?
Despite this, Lake Michigan is the most polluted of the Great Lakes, according to estimates by the Rochester Institute of Technology (RIT). Last year, nearly 22 million pounds of plastic were dumped into the Great Lakes — over half of which were dumped into Lake Michigan — according to estimates by RIT.

What makes lake water look blue?
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.
Why are the Great Lakes so clear?
Fahnenstiel, a senior research scientist at Michigan Tech University, says it’s partly due to less runoff of phosphorous, which is common in farm fertilizer. But the dominant factor, he says, is the explosion of invasive zebra and quagga mussels in the lakes in the past twenty years or so.
Is there blue ice on Lake Michigan?
Where can I see Michigan Blue Ice? Blue Ice is very rare, and requires the right conditions to form. As a result, Blue Ice does not appear every year. Blue Ice typically forms on northern Lake Huron near the Straits of Mackinac, the body of water that separates Lakes Michigan and Huron.
Why is lake ice blue?
Glacier ice is blue because the red (long wavelengths) part of white light is absorbed by ice and the blue (short wavelengths) light is transmitted and scattered. The longer the path light travels in ice, the more blue it appears.
Is Lake Michigan fresh or salt water?
freshwater
The Great Lakes are freshwater ecosystems. Traditionally, Lake Michigan, for example, has been a very low-salt lake, with levels around one milligram of chloride per liter of water. Over the years, due to our increased salt use, that level has steadily but gradually climbed up to 15 milligrams per liter.
