The present invention relates to a fishway mounted on a reservoir by enclosing a river or a valley and, more specifically, to a fishway for effectively guaranteeing the movement of fish especially in the breeding season by providing the fishway which is changeable depending on water level of the river for using water stored by saving a river bank and the reservoir to enclose the river. Generally, the level of water is gradually accumulated as shallow deep water is increased, to occur a phenomenon of which water is rotten after a long period of time. The fishway periodically transports stream of an upper side stored periodically by the reservoir to the river of a lower side by forming a transferring pipe to the lower side of the reservoir in order to prevent the water becoming rotten. |
