Lake Safety Rules for Kids: A Family Guide to Lakes, Beaches and Rivers

In this guide (8 sections)

The gap between pool swimming and open water is wider than most parents realize. According to the CDC, children ages 5 to 14 drown in natural water settings (lakes, rivers, oceans) more often than in pools. The reason is not that kids are worse swimmers in open water — it is that open water adds variables pools never have: currents, temperature swings, murky visibility, uneven bottoms, and distance that fools the eye. Open water accounts for a large share of childhood drownings — see the breakdown by setting in our child drowning statistics center.

A child who can swim a confident freestyle lap at the neighborhood pool may panic in a lake when their feet cannot touch, the water is colder than expected, and the shore looks further than it did from the dock.

This guide — and the free printable checklist — walks you through the four moments that matter most for open water family trips. It draws on guidance from the U.S. Coast Guard, the American Red Cross, the CDC, NOAA, the National Drowning Prevention Alliance, and the American Academy of Pediatrics.

What are the basic lake safety rules for kids?

Seven rules cover most of what goes wrong at a lake. They are simple enough to say out loud in the car on the way there, which is the point — lake safety tips only work if a child can actually recall them standing on a beach.

1. A life jacket, not floaties. In open water, a properly fitted U.S. Coast Guard-approved life jacket for every child who is not a strong swimmer, worn the whole time. Inflatable toys are not flotation devices.
2. Never swim alone, and never past the buoys. Buoy lines mark the drop-off, the boat lane, or both.
3. Enter feet first, every time. Lake bottoms shift. Depth from last summer means nothing this summer, and diving into unknown water is how neck injuries happen.
4. One adult is the designated watcher. Not reading, not on a phone, not in conversation. Rotate the job every 20 minutes so attention does not drift.
5. Get out at the first rumble of thunder and stay out for 30 minutes after the last one.
6. Respect cold water. A lake that is warm on top is often much colder four feet down, and the gasp reflex that causes is what drowns strong swimmers.
7. If you are caught in a current, do not fight it. Float, signal, and swim parallel to shore rather than straight at it.

Great Lakes families need one rule more. The Great Lakes produce genuine rip currents and structural currents along piers and breakwalls — the same physics as an ocean beach, on water that looks like a calm inland lake. Never swim near a pier, jetty or breakwall, and treat posted flag warnings exactly as you would at the coast. Our guide to what beach warning flags mean covers the color system used at most Great Lakes and coastal beaches.

Wondering how a lake compares to the ocean, or whether lakes really have undercurrents? That comparison — and the hazards specific to each — is covered in our guide to lake vs. ocean swimming safety. The rest of this page is the practical sequence: what to do before you leave, on arrival, in the water, and if something goes wrong.

What should you do before leaving home for open water?

Before leaving home, check the weather and water conditions, pack a Coast Guard-approved life jacket for every child, bring a throwable rescue aid, and assign the first Water Watcher. Open water days are won or lost in the kitchen the night before. The prep you do at home decides what happens at the water.

The life jacket question is worth its own line. The U.S. Coast Guard reports that approximately 85 percent of recreational boating drowning victims were not wearing a life jacket. The correlation is so strong that the single biggest thing you can do to prevent an open water drowning is insist on Coast Guard-approved life jackets for every child on boats, docks, and moving water — no exceptions, no "just this once."

What hazards should you scan for when you arrive?

On arrival, locate lifeguards or mark your exact location, read the beach flags, scan for rip currents and river strainers, and set a visible boundary for each child before anyone enters the water. The first 10 minutes at the water are for adults, not kids. Unload, hydrate, sunscreen, and do a full hazard sweep before anyone steps into the water. Rushing this step is how avoidable drownings happen.

Locate lifeguards — or mark your location. If there are lifeguards, note their stand. If there are not, pin your exact entry point in your maps app so you can relay it to 911 in seconds. Every minute saved on location matters.

Read the flags and signs. Beach flag colors are standardized in the U.S.: green (low hazard), yellow (moderate hazard — use caution), red (high hazard — no children in the water), double red (water closed), and purple (dangerous marine life like jellyfish or sharks). A red flag is not a suggestion. If the flag is red, the beach is not open for your children today.

Scan the beach for rip currents. Rip currents are narrow channels of water flowing quickly away from shore. Look for channels of churning, choppy water; areas with noticeable differences in water color; lines of foam or debris moving steadily seaward; and breaks in the incoming wave pattern. If you see any of those signs, move your family to a different part of the beach.

Check river current and strainers. Rivers hide sudden deep drops, submerged logs, and "strainer" branches — tree limbs under or over the surface that can trap swimmers. Never let children wade past knee-deep in moving water without adults in the water with them.

Walk the shoreline for hazards. Glass, fishing hooks, sharp rocks, jellyfish, and blue-green algae. In lakes, algae blooms that look like blue-green paint slicks on the surface are toxic. Do not let children swim or dogs drink where algae is visible.

Mark a visible boundary for each child. Point to a physical landmark — a buoy, a dock post, a flagpole. Kids who swim past a visible marker get called back immediately, before they get out of reach. Distance judgment fails fast in open water.

What are the active supervision rules for open water?

Keep one designated Water Watcher on duty at all times, use touch supervision for non-swimmers, run a buddy system for every child, and keep life jackets on in boats, on docks, and in fast-moving water. Once the family is in the water, the rules are simple but non-negotiable.

One designated Water Watcher at all times. Eyes on the water, within arm's reach of non-swimmers, no phone, no book, no alcohol, no side conversations. Rotate in 15- to 30-minute shifts on a timer. If you want a printable Water Watcher card to hand off, use our Water Watcher duty card.

Touch supervision for non-swimmers. Infants, toddlers, and weak swimmers stay within arm's length of an adult in the water. No exceptions for "just grabbing a towel" or "just checking my phone." The American Academy of Pediatrics defines touch supervision as the adult being close enough to physically reach the child at all times.

Buddy system for every child. No child — not even a strong swimmer — enters open water alone. Each child has a named buddy; they get in together and they get out together.

Life jackets on in boats, on docks, and in fast-moving water — always. Falls from docks into cold water happen faster than rescue can reach.

Skip earbuds and sunglasses for the Water Watcher. Drowning is silent — you will not hear it. Sunglasses cut glare but also make it harder to read a child's face under the water surface. If you need glare protection, polarized lenses help; so does an elevated vantage point.

No diving into unknown water. Murky lake and river bottoms hide rocks, stumps, and shallow spots. Head and spinal injuries from shallow-water diving are life-altering. Feet-first entry only, every time.

What should you do if something goes wrong in the water?

After a safe rescue: Tap and shout; for an infant, tap the bottom of the foot. Check for normal breathing for no more than 10 seconds. If unresponsive and not breathing normally, including only gasping, begin CPR. Lay rescuers should not delay for a pulse check.

Send someone to call 911 and get an AED. If alone with a mobile phone, call on speaker and start care while following the dispatcher. If alone with a child or infant and you must leave to reach a phone, give about 2 minutes of CPR before leaving to call.

Breaths are especially important after drowning. The Red Cross drowning sequence starts with 2 rescue breaths, then cycles of 30 compressions and 2 breaths for a single rescuer. AHA guidance allows trained rescuers to begin with breaths or compressions; do not delay CPR to debate the sequence. If unable or unwilling to give breaths, start chest compressions and follow the dispatcher.

Compress at 100–120 per minute on the lower half of the breastbone, allowing full recoil and minimizing pauses. For a child from age 1 until puberty, use one or two hands; press at least one third of the chest depth, about 2 inches (5 cm). For an infant under 1 year, use the heel of one hand or two thumbs with hands encircling the chest; press at least one third of its depth, about 1.5 inches (4 cm). The 2025 AHA guidance no longer recommends two-finger infant compressions.

For each breath, open the airway with a head tilt and chin lift. Seal over a child’s mouth while pinching the nose; cover an infant’s mouth and nose. Give each breath over about 1 second, only enough for visible chest rise. Continue 30 compressions and 2 breaths. Begin CPR with breaths before applying an AED after drowning. As soon as available, expose and dry the chest, attach pads and follow its prompts; use pediatric pads/attenuation if available. Do not delay CPR to find an AED. Nobody should touch the person during analysis or shock.

Continue until normal breathing or other clear signs of life return, trained help takes over, you are too exhausted to continue, or the scene becomes unsafe. Pause when the AED instructs, then promptly resume. If breathing normally but still unresponsive, maintain an open airway and follow the dispatcher; use a side-lying recovery position if appropriate and no suspected spine injury prevents it. Watch breathing continuously and restart CPR if normal breathing stops.

Why don't pool swimming skills fully transfer to open water?

Pool skills don't fully transfer because open water adds currents, cold, murky visibility, uneven bottoms, and deceiving distances that a clear, known-depth pool never has. Parents often assume that a child who swims confidently at the pool will swim confidently at the lake. They usually will not — at least not on the first trip, and not without preparation. Plan the move from pool to open water deliberately rather than on the first beach day.

Pool water is clear; lake water is not. Pool depth is known; open water depth changes step by step. Pool temperature is regulated; lakes in May can be 15°F colder than lakes in August. Pool edges are close; open water shores can be a long way off. A strong pool swimmer in unfamiliar open water is still a beginner swimmer in that environment.

The AAP's water competency framework — enter the water, surface, turn, float or tread for one minute, and swim 25 yards to safety — is built to transfer across environments. Lessons that focus only on pool strokes do not build the survival skills that open water demands. See our guide to the two self-rescue skills every child needs.

When should you pack up and go home?

Pack up when the weather shifts, a child is shivering or unusually quiet, the Water Watcher rotation breaks down, alcohol is involved, or any child has been submerged. The best families quit early. These are the signs it is time to end the trip:

• Weather shifts — darkening skies, distant thunder, wind change, whitecaps
• A child is shivering, has blue lips, or is unusually quiet after coming out of the water
• The Water Watcher rotation breaks down and no one is clearly on duty
• You have been drinking alcohol and there are still children in or near the water
• A child has been submerged long enough to cough, sputter, or panic — head to an ER even if they seem fine

Ending the day early is not a failure. It is the single most important supervisory skill a parent brings to open water.
