What do Harmful Algal Blooms look like? How will I be able to identify these blooms if I am on the lake?

Discolored water, often with a paint-like appearance, with or without floating scum or mats may be evidence of a Harmful Algal Bloom. Pictures of Harmful Algal Blooms can be found here:  http://www.dec.ny.gov/chemical/81962.html 

It is hard to tell a Harmful Algal Bloom from other non-harmful algae blooms. Therefore, the Cayuga County Health Department recommends that you avoid wading, swimming, boating, and fishing in bodies of water that are discolored or have scum or floating mats present.
