Pets should not be allowed near water where an algal bloom is present.

Algae occurs naturally in bodies of water, and occasionally, large accumulations of cyanobacteria can result in the formation of a potentially harmful algal bloom.

There have been algal blooms at several lakes, reservoirs and streams this summer.
