Migratory fish passage arrangement
A migratory fish passage arrangement arranges water flow past an obstacle upstream of the water's natural flow direction, and includes a hydraulic flow arrangement with a first intake tube from upstream of the dam from an intake point to a location downstream of the dam to a feeding point, where a fish gate allows fish to enter into an elevation tube, to enter from the feeding point in the water in the elevation tube to be transported in the elevation tube to an outlet upstream of the dam. The intake point is higher than the outlet. Also disclosed is a system to guide a migratory fish to pass a dam that includes the migratory fish passage arrangement and additionally a siphon tube from an upstream location with respect to the dam to a downstream location with respect to the dam to constitute a migratory fish return route.
