Stay Alert! Recognizing Open Water Hazards Information on how to stay safe from open water hazards/in open water environments. < PrevNext > Limited Visibility It can be hard to see beneath the surface of natural water due to cloudiness, bubbles or sunlight glare. This can make it difficult to identify underwater hazards (e.g., rocks) or find someone who may be drowning. Be cautious of your surroundings and mindful of everyone in your group.Underwater Currents/TidesOpen water conditions can vary from hour to hour. Currents and tides can change water conditions and quickly push you away from shore or floatation devices. Only swim in designated areas and stay aware of water movement patterns when swimming in lakes, rivers and oceans.Water DepthThe depth of water in natural environments can vary considerably. Sudden drop-offs and sandbars can change water depth unexpectedly, and you may not recognize a shift until it is too late. If unsure of how deep water may be, cautiously enter feet-first.Water TemperatureNatural water temperatures can range significantly, even within the same body of water. Water below 70 degrees can put swimmers at risk of hypothermia, which can quickly become life-threatening. Plan time of day and equipment accordingly.WeatherStrong winds, thunder and lightning can pose a serious risk to anyone in open water. Pay attention to approaching weather and immediately exit the water if you hear thunder or see lightning. Seek shelter and wait for 30 minutes after the last thunderclap before returning to the water. WildlifeMany types of organisms live in natural waters, including fish, snakes, sharks and algae. Some creatures can be dangerous to humans if disturbed, resulting in bites or stings. Try to avoid wildlife as much as possible. Always monitor these conditions closely, as they can shift rapidly in a matter of hours. General Open Water Safety Tips There are other factors to consider while you are in or around open water that may not signal obvious danger. Next time you are in open water, keep these safety measures in mind: Always wear a life jacket that meets U.S. Coast guard requirements when boating or doing a related activity, like tubing. Know your limitations, such as physical fitness capabilities and medical conditions, that may accelerate fatigue. Only swim under lifeguard supervision. If a lifeguard is not present, ensure a responsible adult is designated to supervise without distractions. Always bring a buddy and let someone else know where you will be. Have a pre-established plan in case of emergency. Never swim or boat after dark. Never consume alcohol or drugs before or during any water-related activity, including supervising those in the water.
