Captured in 2007, by Research Epidemiologist, Lorraine Backer; PhD, this image shows a cyanobacterial bloom in a lake. Cyanobacterial blooms occur, when cyanobacteria, otherwise known as blue-green algae, rapidly grow out of control, or “bloom.” These blooms most commonly occur in fresh water, such as lakes, ponds, rivers, and streams. They can look like foam, scum, mats, or paint on the surface of the water, and can make the water appear different colors, including green, blue, red, or brown.
