Rivers, Tubing & Water Safety

Quick reference — the one-page cheat sheet

The whole hub, boiled down to what you can skim the morning of a float. Run the pre-float check, match your river to its manager, and keep the one-liners below in mind on the water.

The pre-float check

Before you launch

The most important safety decision — which river, and what level — happens before anyone touches the water. Run this list every time:

  • Check the USGS gauge

    High, fast, muddy, or rising water is the number-one danger. Know the level before you leave home.

  • Check the weather — upstream, too

    A storm miles upstream can flood your stretch hours later. Flash floods rise in minutes.

  • Check for closures

    The NPS closes the Current and Jacks Fork near 2 feet above normal; other rivers rely on the gauge, the forecast, and local closures.

  • Call your outfitter

    They know today's conditions, the put-ins, and whether the river is even running.

  • Pack life jackets for everyone

    Children under 7 must wear one by law — and a tube is not a life jacket.

  • Pack legal containers

    Sealed, nonglass coolers; a trash bag tied on; no glass on tubes, canoes, or kayaks.

  • Check water-quality advisories

    Look for swim-beach postings and algae-bloom warnings before you swim.

  • Plan your exit

    Know your take-out and your distance, and tell someone your plan and your outfitter's name.

Different rivers, different rulebooks

Who runs which river

The rules on a river come from whoever manages it. Match your river to its manager before you trust a rule:

River / water Who runs it
Current & Jacks Fork National Park Service — Ozark National Scenic Riverways
Eleven Point U.S. Forest Service — Mark Twain National Forest
St. Francis whitewater MDC at the Millstream Gardens put-in; the Forest Service at the Silver Mines take-out
Meramec, Niangua, Huzzah/Courtois, Big Piney, Gasconade, Black, Elk Missouri law plus public/private access and local outfitters — no single agency
State-park swim beaches Department of Natural Resources (DNR)
MDC stream accesses Missouri Department of Conservation (MDC)
Anything with a motor See the Boating hub — registration, the boater card, and BWI are covered there

Skim before you go

Plan & check

Pick the river for your group — a wide, lazy river for families and tubes; a narrow, wild one for experienced paddlers; whitewater for trained kayakers only.

Know spring-fed vs. rain-fed: spring-fed runs cold and clear all summer, rain-fed can be too low in a dry spell and dangerously high after a storm.

The rule of thumb: high, fast, muddy, or rising means don't go. Check the USGS gauge and the weather — upstream too — before every float.

Tell someone your plan and your outfitter's name and number before you put in.

On the water

Wear a life jacket — children under 7 must, by law. A tube is not a life jacket.

Feet up, bottom down — never stand up in a current. If you fall off, float on your back with your feet pointed downstream.

Water shoes, a hat, sunscreen, and water — sun and dehydration sneak up on you. Go easy on the alcohol.

Pack out every bit of trash, and respect private banks — stream access lets you float and wade the streambed, but classifications and high-water marks can be disputed, so use public accesses and ask when unsure (see the Fishing hub).

Containers & trash

Sealed, nonglass — no glass

RSMo 306.325: food and drinks must be in a sealed, nonglass cooler or container, a closable trash bag or container must be attached to your vessel, and glass beverage containers are prohibited on capsize-prone vessels — canoes, kayaks, tubes, and rafts — within the banks of navigable waterways.

No beer bongs / 4-gallon limit

RSMo 306.109: no beer bongs and no alcohol containers holding more than 4 gallons on most rivers — except the Mississippi, Missouri, and Osage.

Foam — on the NPS & Eleven Point

Polystyrene foam ('Styrofoam') coolers aren't banned by one clean statewide statute, but they ARE prohibited on the Ozark Riverways (the Current and Jacks Fork) and the Eleven Point — so on those rivers, leave the foam at home.

Pack out all your trash in a mesh bag, and keep soap and food scraps out of the water. For the full breakdown — including stream access and where you can go — see rules & etiquette, and the Fishing hub for stream access.

Hazards

No life jacket

The biggest factor in river drownings. Wear it — every person, the whole float. Children under 7 must by law.

Cold water

Spring-fed rivers stay cold all summer. Sudden cold-water immersion can disable a strong swimmer in minutes.

Strainers

Fallen trees and logjams let water through but trap a person or boat against them. One of the deadliest hazards — steer well clear.

Low-head dams

Water pours over and churns back on itself in a hydraulic that traps and holds you under. Portage — never float, swim, or paddle over one.

Foot entrapment

Never stand up or try to walk in moving water — your foot can wedge under a rock and the current pins you under. If you're swimming, float on your back with your feet up and pointed downstream.

Undercut rocks and bluffs

Fast water can pull you under a ledge. Keep off the outside of fast bends.

Flash floods

Ozark rivers rise fast. Six inches of fast water knocks down an adult; a foot floats most cars; two feet carries away SUVs and trucks. Turn Around, Don't Drown.

Alcohol

It dulls judgment, balance, and your ability to swim — a factor in a large share of drownings.

Cliff jumping & rope swings

Shallow water and hidden rocks cause serious injuries. On the Current and Jacks Fork, tree-jumping and rope swings are prohibited, and rock or bluff jumping is highly discouraged.

The full plain-English version is on river hazards.

If you capsize

If you capsize, get to the UPSTREAM side of the boat and stay there, so the current can't pin it against a rock with you behind it. Never get between the boat and a rock. Tie your gear into the boat — but never tie a person to a boat.

Helping someone in the water

If someone is in real trouble, call 911 first — or send someone to call — then Reach, Throw, Row, Go: reach with a paddle or pole, throw a rope or float, row to them, and only as a last resort go in. Going in yourself is the last resort, because untrained rescuers are the ones who drown alongside the victim — only do it with a life jacket on and something to reach them with.

Ozark Riverways extras

The Current and Jacks Fork (the NPS Ozark Riverways) have a few rules of their own. The big ones to remember:

Water quality & getting sick

Don't drink the river.

Keep your head out of warm, stagnant water.

Cover any cuts before you get in.

Rinse off after you swim.

Don't swim if you have diarrhea.

Skip water that looks or smells off.

Check beach advisories before you swim, when in doubt stay out, don't swallow the river, and keep dogs away from algae scum. DNR tests designated state-park beaches only — a clean-looking gravel bar isn't a tested beach. The calm, full version lives on water quality & getting sick.

If something goes wrong

Emergency & reporting

  • In an emergency, call 911.
  • Report harmful algal blooms or possible water illness to Poison Help (800-222-1222) or the DHSS hotline (800-392-0272).

For anything with a motor

This sheet is river-and-tube first. If you're putting a motor on the water — registration, the boater card, motorboat equipment, or the boating-while-intoxicated law — that all lives in the Boating hub.

Before you float

Missouri Porch explains; the people who run the river decide.

Last checked: 2026-06-18. Rivers change by the day — the level, the weather, and the water-quality advisories are different every time. Check the live gauge and the forecast before every float, and wear your life jacket.

This is a plain-English summary — not the law, a medical authority, or a substitute for a guide or a swiftwater course. River levels, rules, and advisories change — check the live gauge, the forecast, and the agency or outfitter before you float. In an emergency, call 911.

Heads up: A cheat sheet is a starting point, not the whole story — check the live gauge, the forecast, and your outfitter before every float, and wear your life jacket.
