Sporting Clay: Keep away from the blue-green algae

Published Sep. 4, 2009 - The Florida Times-Union
Massive "blooms" of blue-green algae, known as "cyanobacteria," have created thick green mats along the shorelines of Doctors Lake, the St. Johns River and area creeks.

Algae occur naturally in fresh waters and blooms are normal during warm months, but nutrient pollution is what causes the large, intense blooms we are currently seeing. Nitrogen and phosphorus are two of the biggest culprits. They come from fertilizer washing into our waterways during heavy rain.
