Blue-Green Algae Warnings Issued Across Multiple US Lakes

Multiple states across the U.S. are issuing warnings and advisories due to toxic blue-green algae blooms affecting various lakes and reservoirs. In Colorado's Cherry Creek Reservoir, officials caution people about health risks such as rashes and gastrointestinal issues, advising swimmers to shower immediately after contact and to keep children and pets out of the water. Kansas health and wildlife agencies have issued public health advisories for lakes including Norton Lake, recommending closures or restricted access when hazard levels are detected, and urging the public to avoid contact and report any health incidents. Similarly, North Carolina authorities warn visitors to Lake Norman to avoid swimming, boating, or wading due to toxic algal blooms, emphasizing that blooms can be harmful even if not visually identifiable. In contrast, Kentucky has lifted its harmful algal bloom advisory at Herrington Lake after toxin levels declined, though officials remind the public to remain vigilant and report any suspected blooms. These coordinated responses highlight the ongoing risks posed by harmful algal blooms during peak recreational water use periods, emphasizing caution and public health monitoring.
