Water Advisories Issued for Lake Powell, Lake Norman, Frensham Over Harmful Algae Blooms

The National Park Service has issued a water advisory for Lake Powell due to the detection of cyanotoxins produced by harmful blue-green algae blooms, which have reached concentrations at the high end of safe exposure levels. Visitors are advised to avoid swimming or boating in scummy or algae-filled water and to take precautions such as cleaning and draining boats and gear, keeping children and pets away from affected areas, and showering after contact with the water. Symptoms from exposure to cyanotoxins can range from mild rashes to severe illness, including nausea, vomiting, and seizures, prompting recommendations to seek medical care if symptoms occur. Despite the advisory, recreation at Glen Canyon National Recreation Area remains open. Similar concerns are noted in Arizona, where fish deaths in Becker and Luna lakes are likely linked to harmful algae blooms amid poor water quality conditions. These warnings underscore the risks posed by algae blooms in warm, nutrient-rich waters and the importance of public safety measures.
