Why Swimming in Billings’ Yellowstone River Could Be Dangerous

On a hot summer day, the Yellowstone River might look like the perfect spot to cool off but before you jump in, there are a few serious risks to keep in mind.

While the river is a favorite for floating, fishing, and boating, it’s not exactly the safest place to swim. While swimming in the Yellowstone River in Billings isn’t explicitly illegal, it is strongly discouraged because of the significant safety risks involved.

Strong Currents Can Pull You Under

Even when the surface looks calm, the Yellowstone River can have strong and fast moving currents, especially after spring snowmelt or heavy rain. These powerful flows can quickly pull swimmers downstream, making it difficult to get back to shore or steer clear of obstacles. What starts as a relaxing dip can turn dangerous in seconds.

Cold Water Even in Summer

It might be hot outside, but the water in the Yellowstone stays cold, really cold, thanks to snowmelt and glacial runoff. When you hit that icy water, your body can go into shock. In more serious cases, prolonged exposure can lead to hypothermia, even if the air temperature feels summer perfect.

Debris and Hidden Hazards

Under the surface, the river carries more than just water. Logs, branches, trash, and even things like barbed wire can be floating or stuck just below where you can see. These can injure or trap swimmers, making an already risky situation worse.

Weather Can Turn Fast

Montana weather doesn’t always give you much warning. A clear day can suddenly turn into a storm, bringing lightning, strong winds, or even flash floods. Rising water levels and stronger currents make swimming or boating even more dangerous during or after a storm.

Floating Without a Plan? Think Again

Every summer, people hit the water in tubes or rafts with little more than a drink in hand and that’s where things can go wrong. Without life jackets, the right equipment, or knowledge of the river’s conditions, a relaxing float can end in a rescue call. It’s not worth the risk.

River Rescues Happen Every Year

The Yellowstone County Sheriff’s Office handles multiple river rescues each year and not just in Billings. Their trained teams assist with calls from neighboring counties, too. Thankfully, most situations end without tragedy, but many people are stranded or nearly drown and in reality, these calls are scary and entirely preventable.

If You Fall In Or See Someone Who Does

If you end up in the river and can’t swim to shore, experts say to float on your back downstream with your feet pointed forward. If someone else falls in, don’t jump in after them. Instead, call 911 right away and try to use something like a rope, branch, or even a paddle to reach them from the shore.
