Fishways or ‘fish ladders’, as they are often called, are structures designed to allow the movement of fish upstream around barriers that do not usually allow the ready passage of fish (e.g. small dams). Simple fishways are basically low-gradient channels that are designed to allow the movement of fish around or through the impassable barrier.
