In these new sciences we mentioned that by 2000 they want to see salmon on the Rhine River. They are expected to have it, but salmon running along the river will find man-made obstacles. This is the case of salmon running along the French Garonne River in the Golfech area. The dam of the reservoir, built in it, prevents access to the laying of salmon. The problem is solved by building a fish lift.

Salmon sell. When they approach the dam they will be attracted by a faster stream of water 'and will be attracted in the mouth of the elevator. There every ten minutes will close a gate that catches the fish in a container of 3m3 of volume. The boat goes up with fish inside and leaves them in a canal that takes them to the river after 22 m of height.
