Throughout the summer, National Park Service staff sample and analyze the Blue Mesa Reservoir water for the presence of blue-green algae containing cyanotoxins. The latest testing revealed that concentrations of the harmful algae within the Iola Basin exceed safe public health exposure levels.
Harmful blue-green algae is common throughout Colorado. Algae can multiply rapidly to form blooms and scum, particularly in areas of shallow, warm water. Certain types of algal blooms can produce toxins called cyanotoxins, which can be harmful to humans and animals.
Toxins were recently found at North Willow East, on the east side of Sometimes Island. That general location has been posted with warning signs. Due to shifting winds and currents, other areas in the Iola Basin of the reservoir may also contain these toxins, and notification signs have been distributed to heavily used visitor areas. The park staff advises the public to avoid locations with suspected algal mats in this area, and throughout the reservoir.
Use caution and avoid unnecessary exposure to reservoir water if fishing, boating or recreating. Until further notice, the park recommends that no one swims in, or drinks from, reservoir waters in the Iola Basin. Also, do not allow your pets to drink the water in that area. Contact medical care (doctor or veterinarian) if, after exposure to the water, individuals or pets exhibit nausea, vomiting, digestive distress, breathing problems, seizure or unexplained illness.
All of Blue Mesa remains open to boating and fishing. Be sure to clean harvested fish with treated (potable) water. As always, remember to clean, drain and dry all boats and fishing gear.
Staff monitoring water quality continue to sample critical areas and are monitoring conditions. Check the park website for updates at nps.gov/cure.
