HEBGEN LAKE — Toxic algae is forcing new closures at Hebgen Reservoir. The Corey Springs area is now closed to all water activities after toxin levels in that area increased. Crews will post closure signs at public access points.

The Rainbow Point shoreline also remains closed. Testing shows toxin levels there are still high.

There is some good news for the Yellowstone Holiday area. Toxins there have dissipated, and officials downgraded that area to a warning. Caution is still advised around the water.

Harmful algae blooms cannot be identified just by looking at them. Experts say people should stay out of water that smells bad or looks discolored. The algae can look like pea soup or green paint, and it can float in mats or hang in the water.

Children and pets are at a higher risk of getting sick. They spend more time in shallow water where algae builds up. Pets can also get sick by licking algae off their fur.

These toxins can cause muscle twitching and paralysis, and they can be deadly.

Northwestern Energy is monitoring the blooms and will provide updates if additional restrictions are needed.
