An automatic variable fish way of a water level-sensing type is provided to keep a flow flowing along the fish way uniform by automatically varying the height of the fish way, to make the fish way most effective according to an installed place, and to facilitate maintenance. An automatic variable fish way of a water level-sensing type includes an underwater beam(170) installed to a side of a bank installed to keep water in store, and a fish way plate(110) connected to the underwater beam to constitute the fish way. The underwater beam stands up or overturns by a cylinder(180) varying according to a signal of a water level sensor sensing the level of water stored. The fish way plate is hingably connected to the underwater beam and is moved up and down according to the standing-up and the overturning of the underwater beam. Plural moving units for dispersing load of the fish way plate to sidewalls(140) are formed to the sides of the fish way plate. The moving units are each moved on guides of the sidewalls formed along a moving track of the fish way plate moving up and down according to the standing-up and the overturning of the underwater beam. |
