Don’t let rivers fool you when outside temperatures start warming up. Cold water and swift currents can overpower any swimmer and make it difficult to keep your head above water. After high wintertime flows, there may be hidden hazards at some of your favorite river spots like submerged trees. Additionally, keep in mind that the water flows fast and deep just a short distance from shore. That means you can be easily be swept into a deadly situation whether swimming, tubing, or wading. Wear a life jacket for all river activities.
