Are there Dangerous Animals Lurking in Utah’s Lakes and Rivers?

Thankfully, when swimming in a Utah lake or river, you won’t have to worry about dangerous animals in the water. The state doesn’t have any true water snakes or large aquatic reptiles like American alligators. Instead, the danger lies outside of the water. Still, most animals don’t actively hunt humans. It’s always important to never both a wild animal as they can attack. Even the smallest of animals can defend themselves and spread diseases.

While black bears are more commonly seen in rural areas, they occasionally wander into neighborhoods looking for food after winter.

Keep reading to discover 5 dangerous animals around Utah’s lakes and rivers and what to do if you spot on.

Mountain Lions

In Utah, experts estimate there are a little over 1,000 mountain lions in the wild. Another word for a mountain lion is a cougar. Mountain lions spottings are rare, but more common in the winter as they chase deer down in the valleys. You’re more likely to see a mountain lion if you’re in canyons frequented by deer. If you see one, never run and maintain eye contact. They will chase by instinct. Stand up as tall as possible and speak in a loud and clear voice to scare them away. Most of the time, if a mountain lion is in your way, it’s because you’re near their kittens.

Black Bears

The North American black bear is the only bear species in Utah. Although this animal is dangerous, strong, and powerful, it rarely causes problems. Black bears contribute greatly to the ecosystem and live in forested areas. Experts estimate there are about 4,000 black bears in Utah. Black bears generally stay away from people, however, they can show aggression when hungry. While black bears are more commonly seen in rural areas, they occasionally wander into neighborhoods looking for food after winter. Black bears are so strong they have a bite force of up to 800 PSI. So, what do you do if you encounter a black bear? Stay calm and alert. On the rare chance the bear attacks, fight back or spray them in the face with bear deterrent spray.

Gila Monsters

Have you ever heard of a Gila monster? These unique and very old venomous reptiles are native to southern Utah, but rarely seen, why is this?
