A harmful cyanobacterial bloom (HCB) recreational use Bloom Advisory has been issued for Wind River Lake and the Wind River – Lower Wind River Campground, according to a release issued by the Wyoming Department of Health (WDH) and the Wyoming Department of Environmental Quality (WDEQ) on October 3.
The Wyoming Department of Health (WDH) works cooperatively with the Wyoming Department of Environmental Quality to issue recreational use advisories when cyanobacterial cell densities or cyanotoxin concentrations pose a risk to people engaging in swimming or similar water contact activities in areas where cyanobacterial blooms occur.
HCBs may also pose a health risk to animals.
The WDH is working directly with resource management agencies to ensure signs are posted at these water bodies. Additional details regarding advisories and other HCB resources can be found at WyoHCBs.org.
Bloom advisories are issued when a HCB is present and cyanotoxins may be present. Toxin advisories are issued when cyanotoxins exceed recreational thresholds.
Water bodies under an advisory are not closed since HCBs may only be present in certain areas and conditions can change frequently.
Advisories will remain in place until blooms have fully dissipated and cyanotoxin concentrations are below recreational use thresholds identified in Wyoming’s HCB Action Plan.
If you encounter a potential HCB, the Wyoming Department of Health and the Wyoming Livestock Board recommend the following:
- Avoid contact with water in the vicinity of the bloom, especially in areas where cyanobacteria are dense and form scums.
- Do not ingest water from the bloom. Boiling, filtration and/or other treatments will not remove toxins.
- Rinse fish with clean water and eat only the fillet portion.
- Avoid water spray from the bloom.
- Do not allow pets or livestock to drink water near the bloom, eat bloom material, or lick fur after contact.
- If people, pets, or livestock come into contact with a bloom, rinse off with clean water as soon as possible and contact a doctor or veterinarian.
