CATRON COUNTY, N.M. — The New Mexico Environment Department (NMED) is warning visitors to avoid contact with water at Quemado Lake after recent samples confirmed the presence of harmful algae and toxins.
Known as harmful algae blooms (HABs), these outbreaks occur when certain types of algae grow excessively, producing toxins that can pose health risks to humans and animals. The blooms may appear blue, bright green, brown, or red, and often resemble scum or floating grass clippings.
NMED advises visitors to take the following precautions:
- Do not swim, wade, or engage in water sports.
- Keep pets and other animals away from the lake and shoreline.
- Avoid areas with visible algae while boating.
- Do not drink untreated surface water.
- Rinse fish with clean water before cooking and eat only the fillet.
- Supervise children and keep them away from algae-covered areas.
If you suspect an algae-related illness, contact the New Mexico Poison Information Center at 800-222-1222. For animal-related concerns, call 888-426-4435 or the Pet Poison Helpline at 855-764-7661.
NMED continues to monitor lake conditions and reminds the public: if the water looks or smells unusual—like paint, pea soup, or floating debris—it’s best to stay out.
