Many dams and spillways are equipped with structures such as fish ladders or passages to allow for the freer movement of fauna or livestock through the stream. Unfortunately the design of these structures can at times make them attractive for people to play in, engage in extreme sports activities, or otherwise misuse. These are both delicate structures and dangerous structures. They pose considerable slipping and drowning hazards due to currents and animal activity. Like any other dam structure, these areas should be avoided.
