Blue-Green Algae Blooms

In the summer of 2010 national and international concerns for the increase in blue-green algae blooms hit home.  In Ohio there were several reports of severe blue-green algae blooms that halted recreational activities on local lakes including Ohio’s Grand Lake St. Mary and Shawnee State Public Golf Course.

So what is the big deal…It’s just algae, and I get algae on my pond every year.

Blue-green algae blooms are microscopic bacteria that occur naturally on the surface.  When the environment is just right (light, temperature, levels of nutrients, little water movement) blue-green algae will thrive.  Like other alagae blooms, blue-green algae, can be treated with algaecides like copper sulfate, but when it starts to die toxins are released that can be harmful to people and other wildlife. 

Blue-green algae blooms create toxins that may be harmful to humans, pets, livestock, wildlife, and fish.  Health effects include rashes, eye irritation, and gastrointestinal problems.  In the most severe cases serious illness or death could occur depending on exposure.

The best way to avoid ill effects from a blue-green algae bloom is to stay away from the water and do not eat fish from the water that has been affected.  Hopefully this season will pose fewer blue-green algae blooms.
