A device contains fish channels 2 placed in the water basin 1 with water receiving windows 4 and floats 5 mounted on the windows. The channels are made as non-pressure pipes, which are laid in the ditches at the water basin edges or on the supports fixed on the slope in the form of serpentine with inclination of 1,5-2,5%. The lower ends 7 of the pipes are led to the afterbay of the water basin. In the pipes passing on 100m depth from the maximum allowed water level in the water basin there are reinforcing rings made of wear-resistant substance.
