Canoes and ladders are not often thought of together: canoes are for traversing bodies of water and ladders are for covering heights on dry land. For one unlucky kayaker in Michigan, however, getting stuck up a ladder in a canoe became a reality. You may have guessed by now that we're not talking about any ordinary ladder, but a fish ladder. Fish ladders are installed within man-made river barriers to provide a route for migratory fish back to their spawning grounds and can take several forms. The most common type, and the one in question in this case, is the pool and weir type. A series of small dams and pools creates a shallow incline with the correct speed of water flow for the species of fish that are meant to be using the ladder. The fish can jump over the low dams and rest in the pools before making the next jump. They are able to bypass hydroelectric dams and other man-made river features and make their way back to their spawning grounds. It was one of these pool-and-weirs that caught the unsuspecting kayaker out. He had been drawn to the mouth of the fish ladder and became stuck in the first dam. He lost his paddle soon after that, and then his vessel started taking on water. A bystander noticed what was happening and called the police. Both the police and the fire department attended, and rescued the man by throwing him a rope and pulling him toward their rescue boats. No-one was hurt in the incident or subsequent rescue, but it was surely a different experience for the fire department; usually they are rescuing people with a ladder, not from one!
