The invention discloses a dam and an overflowing structure thereof. Top groove openings of overflowing grooves and/or drainage grooves in the overflowing structure are provided with flowing grooves which extend from leftward to rightward. The flowing grooves and groove walls of closed ends of grooves where the flowing grooves located are arranged at intervals frontward and backward. The groove bottoms of one or more ends of the flowing grooves are connected with adjacent side groove walls of the overflowing grooves and the drainage grooves. The ends, positioned at the adjacent portions, of the overflowing grooves and the drainage grooves, of the flowing grooves are opening ends. The opening end of each flowing groove is communicated with the corresponding top groove opening of the corresponding side of the groove where the flowing groove located, or the opening end, on the top groove opening of the groove of the corresponding side, of the other flowing groove. The two front and rear side groove walls of each flowing groove are added into an overflowing line of the whole overflowing structure. By adding the groove walls of the original closed ends of the overflowing grooves and the drainage grooves, the flood discharging mode that the whole overflowing structure has at least four overflowing portions is achieved, and therefore the length of the overflowing line of the whole overflowing structure can be increased, and the flood discharging speed can be accelerated.
