CASPER, Wyo. — Keyhole Reservoir has been added the the list of bodies of water in Wyoming where the Wyoming Department of Environmental Quality have confirmed the presence of harmful algae blooms.
Recreational use advisories due to the confirmed presence of cyanobacterial blooms are in effect at the following Wyoming lakes or reservoirs:
- Pathfinder Reservoir
- Lower North Crow Reservoir
- Big Sandy Reservoir
- Eden Reservoir
- Woodruff Narrows Reservoir
- Boysen Reservoir
- Ocean Lake
- Saratoga Lake
- Wheatland Reservoir #3
- Leazenby Lake
- Seminoe Reservoir
- Keyhole Reservoir
The Wyoming DEQ is also investigating possible harmful algae blooms at:
- Brooks Lake
- Jackson Lake
- Gillette Fishing Lake
- Huck Finn Pond
The Wyoming DEQ offers details regarding the blooms at each body of water on their “Harmful Cyanobacterial Bloom (HCB) Advisories in Wyoming Waters” webpage.
“HCBs are also referred to as harmful algal blooms (HABs) since cyanobacteria are commonly known as blue-green algae,” the Wyoming DEQ explains. “The Department of Health issues advisories to inform the public that there may be health risks for people and animals in areas where HCBs occur.”
“Lakes and reservoirs under a recreational use advisory are not closed since HCBs may only be present in certain areas of the waterbody and conditions can change frequently. The advisory will remain in place until the bloom has fully dissipated and cyanotoxin concentrations are below recreational use thresholds identified in Wyoming’s HCB Action Plan, or until the primary recreation season ends on September 30th, whichever comes first.”
People who encounter possible harmful blooms are provided the following recommendations from the Wyoming DEQ and Wyoming Livestock Board:
- 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.
