(HABs) are often called blue-green algae, are commonly found in Ohio lakes, slow-moving rivers, and ponds. There are many kinds of species of blue-green algae that do not produce toxins, but some can cause HABs. What causes HABs you may ask is when there is a shallow body of fresh water, warm temperatures, sunlight, and excessive amounts of nutrients (nitrogen and phosphorus) in the water.
In the right environment, the numbers of blue-green algae can increase at a rapid rate or "bloom" in a body of water. Some HABs are visible, and can be seen as a thick mats or scum on the surface of the water. These mats can vary in color, including bright green, bluish-green, or even sometimes a red or maroon.
