Planning to hit the legendary Yellowstone Boat Float this weekend, or just trying to cool off in the chocolate-milk-colored waters sometime this summer? Montana Fish, Wildlife & Parks (FWP) has a few crucial rules of the river to make sure your weekend stays a “fun story” and doesn’t turn into a cautionary tale.

Montana’s rivers look like a blast right now, but they are packing some serious attitude. Here is what you need to know before you launch:

The Realities & Hazards

Floating the Yellowstone comes with inherent risks. Between the temporary construction bridge at Duck Creek near Billings and another tricky bridge down by Reed Point, the river has essentially set up its own obstacle course. Rivers change their minds constantly, throwing brand-new hazards in your path. Unless you want to test your insurance policy, make sure you actually have the skill set and proper gear to steer your craft safely.

Lifejackets Aren’t Optional

If you’re on the water, you need the gear. Lifejackets save lives—period.

• Every single watercraft must carry one wearable, properly fitting Personal Floatation Device (PFD) for each person on board.
• They need to be in good condition and readily accessible (not buried under the cooler).
• Crucial Rule: Children under 12 must wear their PFD at all times while the watercraft is in motion.

Don’t Be a Jerk (Be Respectful)

The vibes on the river only stay immaculate if everyone plays nice. Be mindful of anglers trying to fish and other floaters trying to relax. When it comes to the land, pack out every single piece of your garbage, and don’t go trampling the vegetation at campsites. Leave it better than you found it.

Do You Have Your Conservation License?

Before you even touch the water, make sure you’re legal. Any recreational user accessing a Fishing Access Site (FAS) or other state-owned land is required to have a Conservation License.

Quick Tip: If you’ve already bought your hunting, trapping, or fishing licenses and tags for the year, you’re good to go—you already have one!

If you still need to grab yours, you can get more information and buy it directly online at the Montana FWP Conservation License Page.

Stay safe, watch out for those hidden river hazards, and have an awesome weekend out there!
