Anglers and other recreationists are warned of a harmful algal bloom in Wheatland Reservoirs #1 and #3.

Laramie - Harmful algal blooms are dense concentrations of cyanobacteria or blue-green algae that pose a health risk to humans, pets, and livestock. Under normal conditions, cyanobacteria are present at low levels and play an important role in aquatic ecosystems. Harmful concentrations typically occur when there is an overabundance of nutrients in the water. Humans, pets, livestock, and wildlife could be at risk from contact with water during the bloom. Fish and other aquatic animals could also be killed. The algae blooms have been widespread across Wyoming in recent years. Anglers and other recreationists are urged to avoid contact with the water in areas where algae form scum. Other safety tips include:

  • Do not drink the water; boiling, filtration and/or chlorination will not make the water safe.
  • Caution should be taken when eating fish as health effects remain unknown. Rinse fish with clean water and eat only the fillet portion.
  • Do not breathe water spray in areas of the bloom.
  • Keep pets and livestock away from the water. Do not allow animals to drink the water, eat dried algae, or groom themselves after playing in the water.
