We were given a callout at the hut where we had to interview the reporting party and formulate a plan, execute and complete the mission start to finish. Today was an overdue fisherman. Medical complications of diabetic, and alcoholism. Located car, tracked and then rescued victim from sandbar in river with a swing and pivot move. Swift water, hypothermia and Diabetic emergency were factors. Overall very good training to learn viewpoint of a coordinator and Sheriffs office. We learned a lot and had a good day on the river.
