Toxic Blue-Green Algae Detected at DeWeese Reservoir; CPW Issues Warning

Colorado Parks and Wildlife (CPW) is warning the public about the presence of toxic blue-green algae at DeWeese Reservoir in Custer County.

CPW is urging people to avoid contact with the water after tests confirmed dangerous levels of toxicity. Elevated algae levels were also visible as a turquoise-colored film on the surface of the reservoir, located north of Westcliffe.

If a person or pet comes into contact with the water, CPW advises showering immediately to reduce health risks.
