A firefighter swam out to rescue a boater suffering medical problems and pulled his boat to shore Wednesday morning on the Columbia River in Richland. Crews from Columbia Basin Dive Rescue, Kennewick and Benton County responded about 9 a.m., said Battalion Chief Ron Duncan of the Richland Fire Department. The boater was west of the Edison Street interchange near Bateman Island. The older man called a friend in Eltopia who then called 911, Duncan said. Emergency officials then tried to pinpoint the boat’s location by triangulation. The boater was taken to Trios Southridge Hospital.
