Here’s the release from Colorado Springs Utilities:
There is an increasing occurrence of toxic blue-green algae in reservoirs across the United States this year, forcing the limitation of recreational access to the bodies of water for public safety.
In a recent test at Pikeview Reservoir, a popular fishing lake in central Colorado Springs and part of our water system, the bacteria was identified.
While the reservoir is still safe for fishing, as a precautionary meaure, humans and pets are prohibited from entering the water until further notice. Anglers are directed to thoroughly clean fish and discard guts.
We have removed Pikeview 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 our community.
Presumptive testing has indicated levels of less than 5 mcg/L.
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. For questions regarding health impacts of exposure, contact the El Paso County Health Department or Colorado Department of Public Health and Environment.
Warming temperatures have contributed to the growth of the bacteria.
From The Colorado Springs Gazette (Liz Henderson):
The popular fishing lake that lies just south of Garden of the Gods Road tested above acceptable limits for the bacteria the news release read. The water is still safe to fish in, but humans and pets are not allowed. Anglers are asked to clean the fish thoroughly and remove guts, according to the news release.
The reservoir has been removed as a drinking water source, Utilities stated, however there are no concerns about the tainted water affecting the community.
