Drownings in Utah's lakes and reservoirs have prompted Utah State Park Rangers to urge swimmers and boaters to use caution while on the water.

"Accidents can happen suddenly and at any time," said Dave Harris, boating coordinator. "Wearing a life jacket while boating is synonymous with wearing your seat belt on the highway — they are both proven life savers."

Nearly 80 percent of fatalities from boating accidents could be prevented if a life jacket had been worn. It is likely that nearly 100 percent of swimming-related drownings could be prevented if a life jacket or other floatation device is used.

Other reminders:

• Utah law requires children under 13 to wear a properly sized life jacket when on a boat. It is a safe and smart practice for everyone, including adults, to always wear a life jacket when on the water.

• Never swim alone; always swim with a "buddy." Parents should make sure they are watching their children, even when other adults or a lifeguard are present.

• Don't drink alcohol if you are planning to swim or go boating. Alcohol slows reaction time and affects balance and judgment.

• Be aware that in natural bodies of water, swift currents, deep water and/or a sudden drop-off can get you in trouble, even if you are a good swimmer.
