MIGRATORY FISH PASSAGE ARRANGEMENT
The invention shows embodiments of a hydraulic flow arrangement, to arrange the flow of waters past an obstacle in the flow, such as a dam in the riverbed, upstream the natural flow direction of the water in the riverbed, wherein the arrangement comprises a first intake tube from an upstream location with respect to the dam from an intake point to a downstream location with respect to the dam to the feeding point, where there is a fish gate to give access to the fish to enter an elevation tube, to enter from said feeding point in the water in said elevation tube to be transported in the elevation tube to an outlet at upstream location with respect to the dam, wherein the intake point is at a higher water height than the outlet. Invention shows also embodiments of a hydraulic flow system that comprises an embodied said arrangement and additionally a fish passage passing turbine tunnels to the downstream direction as a return route for the fish.
