A movable fishway is provided to adjust the height of the fishway to store water and adjust the angle of the fishway without additional equipment. A movable fishway includes a waterway body, a sub-fisway(30), a sealing unit, a water supply uint(50), a fishway falling unit(60), and an extension space part. The waterway body has a movable space formed on a waterway for a fishway connected to a girder. The sub-fishway(30) is connected to the movable space and rotates according to the water level of the movable space. The sealing unit is installed between the inner peripheral surface of the movable space and the outer peripheral surface of the fishway. The water supply unit(50) has an end installed in the upper portion of a girder to supply water to the movable space. The fishway dropping unit(60) drops the fishway by discharging water in the movable space in the flood. The extension space part extends the inner space of the movable fishway to the inside of a guide part in order to a movable waterway. |
