⚠️ A Toxin Advisory is in effect at several locations at the reservoir due to harmful cyanobacterial blooms (HCBs).

📍 Brannon Campground, Cottonwood Campground, Fremont Bay Campground, Marina Campground, North Swim Beach, Sandy Hills Campground, South Muddy Campground, Tamaraska Campground, Tough Creek Campground, Below the Dam on the Wind River, Lower Wind River Campground, and Upper Wind River Campground

At these locations, toxin levels are unsafe for swimming or fishing; avoid areas near blooms.

A Bloom Advisory also remains in effect for the entire reservoir.

The Wyoming Department of Environmental Quality (DEQ), the Wyoming Department of Health, and the Wyoming Livestock Board recommend that you:

🚫 Do not swim in or come into contact with green water, floating scums or clumps.
🚫 Do not ingest water from a bloom; boiling, filters, and other treatments will not make the water safe.
🎣 Rinse fish with clean water and eat only the fillet portion.
💧 Avoid water spray from a bloom.
🐾 Do not allow pets or livestock to drink water, eat bloom material, or lick their fur after contact.

If contact occurs, rinse with clean water immediately and contact a doctor or veterinarian if symptoms develop.

Learn more, view the live advisory map, or report a suspected bloom at WyoHCBS.org.

Visitors can still enjoy hiking, camping away from the shoreline, and wildlife viewing. Please keep a close eye on kids and pets near the water.

Boysen National Public Lands Day. Thanks to the participants helping to pull up those terrible puncturevines (aka goat heads) This awesome crew was able to pull up about 200 gallons of plants!!! And then we ran a burr roller over where they were picking up as many seeds as we could. We threw them all in the dumpster and ask if you see any of these pesky weeds during your visit to do the same!
