Definition
The attraction flow is used to create a continuous corridor for migration between the tailwater of a damming structure and the fishway. Fish that want to ascend a river need a perceptible flow in the area where, due to their orientation, they meet with a transverse structure and where they are naturally looking for routes further upstream. From this point the attraction flow leads them into the fishway, which means that the effectiveness of the attraction flow is confined to the area of the fishway entrance.
