Algal blooms in inland waters

Algae occur naturally in inland waters such as rivers, streams and  lakes. When conditions are ideal for growth, an algal bloom can occur.  During a bloom, the water becomes less clear and may look green,  blue-green or greenish-brown. Scums can form during calm weather when  several bloom forming species rise to the surface. This can look like  paint, mousse or small clumps.

Cyanobacteria or blue-green algae, a type of blooming algae, can  produce toxins. These toxins can kill wild animals, livestock and pets.  They can also harm people, producing rashes after skin contact and  illnesses if swallowed.

Algal blooms block sunlight from reaching other plants in the water.  They also use up oxygen in the water at night which can suffocate fish  and other creatures. Oxygen is also used up when the bloom decays.
