DescriptionNonvisible cyanobacteria HAB.png
English: Nonvisible cyanobacteria HAB. Just because you cannot see a HAB in the water clearly does not mean that a bloom is not occurring in a water body. This picture shows a bloom at Maumee Bay State Park that has a high toxin concentration of cyanobacteria (greater than 5.0 micrograms/liter), and yet the cyanobacteria are not easy to see.
