Toxic Algae Prompts Warning at Colorado Reservoir

Colorado Parks and Wildlife has issued warnings about toxic blue-green algae blooms at Cherry Creek Reservoir, urging visitors to avoid swimming and keep children and pets away due to health risks. Cyanobacteria can quickly multiply and release toxins that cause skin irritation, gastrointestinal issues, or liver damage in humans and animals. Some visitors have recently reported illnesses after exposure, prompting criticism of the timing and visibility of official warnings. Signs have been posted in affected areas, and while fishing and boating are still permitted, officials recommend rinsing fish and showering after contact with the water. The blooms are currently limited to specific parts of the reservoir, but caution is advised as conditions may change. Monitoring and updates continue as officials track water quality.
