A recent water sample shows cyanobacteria are present, and they can be harmful to pets and humans.
CASCADE, Idaho — Health officials are warning recreationists about using Cascade Reservoir due to the presence of a harmful algae bloom in the water.
The Idaho Department of Environmental Quality has been monitoring the reservoir and says a recent water sample shows that concentrations of a toxin-producing cyanobacteria are present. These type of bacteria can be harmful to humans and pets.
Central District Health and DEQ have issued a health advisory for reservoir users.
Cyanobacteria are a natural occuring in bodies of water, however when temperatures rise, their populations can bloom and toxic chemical compounds, or cyanotoxins, can be released into the water.
Algae blooms may look like mats, foam, spilled paint, or surface scum, and have a foul odor. They can move around to different areas, water depths and change in severity.
