Water & swimming safety — you're the lifeguard

Lake and river swimming isn't a pool: the water is murky, it drops off fast, it's colder than it looks, and no one is watching but you. A few habits keep a great day from turning into the worst kind.

The one that matters most

No lifeguard means you're the lifeguard. Drowning is fast and silent — it rarely looks like it does in the movies. Assign a water watcher who isn't on their phone, watch kids and weak swimmers constantly, and always swim with a buddy.

Wear a life jacket

Wear a life jacket if you're not a confident swimmer, and put kids in one — use the loaner stations if you didn't bring your own.

Never dive into unknown water

Never dive into unknown water. Enter feet-first, every single time — lakes and rivers hide rocks, stumps, and depths that shift overnight.

Respect the drop-off & cold

Respect the drop-off and the cold. A beach can go from ankle-deep to over your head in one step, and deep or spring-fed water stays cold enough to sap your strength fast.

Skip the alcohol

Skip the alcohol around the water, and keep a sober adult watching it.

Watch the weather & the water

Watch the weather and the water's color — get out when storms threaten, and stay out of scummy or bad-smelling water (a possible algae bloom; see the Rivers & Tubing hub). Check the posted beach water-quality sign.

Know the beach testing

The DNR tests designated state-park swim beaches weekly from Memorial Day to Labor Day; by law, a geometric mean above 190 E. coli per 100 mL triggers a 'swimming not recommended' posting (RSMo 640.080). A result is a snapshot, and a clean-looking swimming hole is still untested natural water.

If someone's in trouble

Reach, Throw, Don't Go

If someone's in trouble: Reach, Throw, Don't Go. Reach with a pole or a branch, or throw something that floats — don't swim out unless you're trained, because a panicking swimmer will pull you under. If you must go in, bring flotation. Call 911.

Check before you swim

Before you swim, check the posted beach status, the weather, any algae or scum, the water's clarity, recent heavy rain, drop-offs, boat traffic, and whether everyone has a properly fitted life jacket. The DNR's beach data is a snapshot for designated beaches — not a guarantee for every cove or swimming hole.

Before you go

Missouri Porch explains; the agency that runs the trail or beach decides.

Last checked: 2026-06-18. Trail rules, e-bike access, and beach conditions change with the season and the manager — and out here, no one is watching out for you. Check before you go, carry water, and watch the kids.

This is a plain-English summary — not the law, a medical authority, or a guarantee of safety. Trail rules, e-bike access, and beach conditions change — check the managing agency before you go. In an emergency, call 911.

Heads up: This is a plain-English safety summary, not medical advice. The biggest thing you can do is keep a sober adult watching the water — and in an emergency, call 911.
