Many Oregonians are drawn to river recreation in the summertime, whether that means swimming, kayaking, boating or floating. This year, heavy spring rains and snowpack mean rivers are running fast and cold, even when the weather is hot. That can lead to swimmers getting swept away by strong currents or experiencing cold shock. There have already been rescues, and some drownings, in the region’s rivers this summer. We talk with Shawn Mullen, a captain with the Clackamas Fire District about his experience with water rescues and how to stay safe.
