Good swimmers are generally at less risk of serious mishaps in the water than poor swimmers, but even a good swimmer can drown. Preventing surprise and panic requires learning what to do before getting into the water. Many drownings involve people who did not plan to enter the water. Even when they plan to enter the water, many people underestimate the risks and overestimate their ability, or that of their children in water. Those completing entry-level swim lessons, particularly young children, may still not have the basic skills and knowledge for water competency. They still need close and direct supervision. Even those with good swimming skills may not be safe due to other factors, such as unfamiliar waters, water hazards, medical emergencies, alcohol or drug use, or other unsafe conditions.
SWIMMING SKILLS: Essential swimming skills include being able to enter the water and resurface, controlling breathing, floating, turning, and moving to safety in the water and exiting. However, the water environment, the activity, and even what the person is wearing can alter their ability to perform these skills. Basic swimming skills may be adequate to swim a short time and distance in the deep end of a swimming pool, but greater skill and comfort in the water are needed when swimming in a lake, river, or ocean; in cold or rough water; and in waves or current. The table below provides swimmers and parents with some reasonable guidelines to assess basic water competency and skills to look for when evaluating a swim lesson and water safety program. These swim skills should be seen as a foundation for gaining more experience and comfort in the water.
The American Red Cross recommendations for water competency provide a starting point for assessing minimum swim skills for common pool environments. Those are included in the middle column of the table below, including the minimum proficiency to control breathing, float or tread water, turn in the water, and swim 25 yards using any type of stroke. Anyone lacking such basic skill levels should be closely supervised, stay in shallow water, or wear a life jacket, and seek instruction. A person just able to meet the American Red Cross criteria for water competency is still a novice, not a good swimmer and may not yet be ready for instruction or participation in various activities in different water environments beyond pools such as snorkeling, wakeboarding, surfing, or assisting with in-water rescues. Advanced skills are generally best acquired through specialized courses and may not be included in generic learn-to-swim progressions.
HELPING OTHERS: Everyone should always swim with general supervision such as lifeguards and water watchers. Children without basic swimming skills should be directly supervised by a water watcher who is within arm’s reach. Knowledgeable, attentive, supervision of all swimmers is important for drowning prevention and response, particularly for toddlers, children, and teens, even when lifeguards are on duty. Supervision may be provided by designated water watchers such as parents and youth leaders who are alert, not distracted (reading, using a smart device or phone), not using alcohol or drugs, and focused on those near or in the water.
Ideally, water watchers themselves should be fully water competent, knowing safe, simple rescue techniques.
