The Wyoming Department of Health issued another cyanobacterial advisory Wednesday.

Officials detected a bloom of the potentially dangerous blue-green algae at the northern swim beach of Boysen Reservoir. Blooms were also found in Fremont Bay and western coves of the bay, the Wyoming Department of Environmental Quality said in a release Wednesday.

Lakes under recreational advisories are not considered closed as the blooms may only be present in certain areas and conditions can change frequently.

The Wyoming Department of Health is working with Boysen State Park to post advisory signs around Boysen Reservoir.

The Wyoming Department of Health and Wyoming Livestock Board recommend the following precautions:

  • Avoid contact with water in the vicinity of the bloom, especially in areas where the bloom is dense and forms scum.
  • Do not drink water from the bloom. Boiling or otherwise filtering the water doesn't make it safe to drink.
  • Rinse fish with clean water and eat only the fillet.
  • Avoid water spray from the bloom.
  • Do not allow pets or livestock to drink water, eat bloom material or lick fur after contact.
  • After coming in contact with the bloom, rinse off with clean water as soon as possible and contact a doctor or veterinarian.
