Blue-green algae has been discovered in Pikeview Reservoir. It's still safe for fishing, but humans and pets are prohibited from entering the water.

Pikeview Reservoir, a popular fishing spot in central Colorado Springs and part of our water system, has tested positive for blue-green algae. While the reservoir is still safe for fishing, humans and pets are prohibited from entering the water until further notice. Anglers are directed to thoroughly clean fish and discard guts.

Pikeview has been removed as a source for drinking water until the reservoir is determined to be clear of the algae. There are no concerns about this affecting water supply for the community.

“It’s our responsibility to provide safe, reliable drinking water to our community and to always consider public safety at our reservoirs. We will continue to closely monitor our reservoirs and take appropriate actions,” Earl Wilkinson, Chief Water, Compliance and Innovation Officer said.

We conduct more than 400 water quality tests a month and collect approximately 12,000 water samples throughout our water system annually. With the increased risk of the blue-green algae, we are increasing the frequency of testing reservoirs at lower elevations.

In the past several years, there’s been increasing occurrence of toxic blue-green algae in reservoirs across the United States, forcing limitation of recreational access to the bodies of water for public safety.

Sickness including nausea, vomiting, rash, irritated eyes, seizures and breathing problems could occur following exposure to the blue-green algae in the water. Anyone suspicious of exposure with onset of symptoms should contact their doctor or veterinarian.
