Lake Erie’s algae blooms are caused by runoff pollution. This type of pollution occurs when rainfall washes fertilizer and manure spread on large farm fields into streams that flow into Lake Erie.
What is wrong with Lake Erie?

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. Some cyanobacteria blooms can grow rapidly and produce toxins that cause harm to animal life and humans, so scientists describe them as harmful algal blooms (HABs).
Why does water become green?
Your water is green because of an explosive growth of small algae and phyto- and zooplanktons. Algae love the higher pH, but even in a balanced pond, algae are still there. If they’re kept under control, they won’t multiply. If the water is not balanced, algae will multiply quickly making the water “green”.
Why are mountain lakes green?
The lakes in the mountains that have vivid blue and green colours are glacier fed. As the melt water from a glacier starts to flow in the spring time it carries with it glacier silt or rock flour. The sunlight that reflects off these particles is what gives the lakes their spectacular turquoise blue or green colour.

Soil and fertilizer runoff from a farm after heavy rains; such runoff can lead to algae blooms. A buoy deployed by the Center for Fresh Waters and Human Health to track water quality in real-time. View of Toledo in September 2017, showing an algae bloom where Lake Erie meets the Maumee River.
What causes the color of the Great Lakes?
Sediment most often colors the Great Lakes in the spring and fall when transitioning weather patterns bring storms and strong winds.
