Prospect Lake Closed Due to Toxic Algae

Effective immediately, Prospect Lake closed until further notice

The City of Colorado Springs has closed Prospect Lake, in Memorial Park, effective immediately, until further notice. A precautionary water sample taken from the lake Friday morning, Aug. 9, by the Colorado Department of Public Health and Environment (CDPHE) tested positive for mycrocystin toxin, which is produced by cyanobacteria, also known as blue-green algae.

“Given today’s positive test for mycrocystin toxin, we have closed Prospect Lake for usage,” said Erik Rodriguez, health, safety and environmental specialist with the Parks, Recreation and Cultural Services Department. “CDPHE will continue to test weekly until the bacteria clears up.”

Staff from the Parks, Recreation and Cultural Services Department have closed and roped off the swim beach and closure signs have been posted. The following activities are prohibited during this time:
• Swimming
• Bathing
• Paddle boarding
• Annual permitted motorized and non-motorized boating of any kind, including water activities like tubing and water skiing
• Rentals will not be available during this time
• No pets are allowed

While visitors are advised to stay out of the water, they can still enjoy the numerous other amenities provided at Memorial Park, including fishing in the lake from the designated fishing areas. Fishing areas will remain open, though anglers are urged to clean fish well and remove guts.
