Locations Most Affected

Some of the most affected areas include Barr Lake, Cherry Creek Reservoir, Road Canyon, and Deweese Reservoirs.

Blue-green algae can pose health risks to humans and pets. Avoid swimming, paddle boarding, or allowing your pets to enter waters with visible algae blooms. If exposed, rinse off immediately.
