About Blue-Green Algae
Blue-green algae does not look like traditional green algae, which typically forms in a mat on the surface of the water. Rather it can appear like small grains of green sand at the water surface. There are different types of bluegreen algae that have varying appearances. Some may resemble spilled paint around the edge of the stock dam, some will give the entire water source a pea-green appearance, while others will have a teal green appearance. Different species of blue-green algae contain various toxins, which can poison livestock, resulting in rapid death. Blue-green algae will bloom when weather is hot and winds are calm. As the algae begin to die, gas is produced in the cells causing the colonies to float to the water surface. The wind blows the algae blooms to the shorelines resulting in their concentration and easy access to livestock. Identification of blue-green algae blooms in water can be difficult because the blooms appear and disappear rapidly.
