FIELD: hydraulic engineering. SUBSTANCE: water-jet deflector has barrier of vertical louver plates installed in canal at angle to its axis. Attached to upper ends of plates are deflectors of flexible rubber-fabric material. Attached to lower ends of plates, at the end of each section of barrier, are partitions. Reduced spacing of louver plates towards fishway and presence of flexible deflections assist in direction of young fish towards fishway. EFFECT: higher efficiency. 5 dwg
