Algal bloom, nuisance algal blooms, green algae, diatoms, harmful algal blooms, cyanobacteria
Did you know that algae are a natural part of ponds, lakes, streams, and rivers? These organisms grow in the water (plankton) and on rocks, plants, and other surfaces (periphyton) and sometimes periphyton slough off into the water (seston). Most of the time these algae are hardly noticeable in waterbodies; however, sometimes they can form very noticeable algal blooms.
