    Abstract: A sealing system for a water flow control gate is provided. Each of a plurality of panels has an upper edge extending the length of the panel with a flat surface rounded upward to a wall at the rear side of the panel. The lower edge of each panel has a central perpendicular foot extending the length of the panel with side flanges and a neck between the central perpendicular foot and the rest of the panel. At each end of each panel is a vertical channel extending across the end of the panel. A horizontal sealing strip on each panel surrounds the central perpendicular foot and extending the length of the panel and a vertical sealing strip is positioned within each vertical channel, so that water flow through the water flow control gate is prevented by the horizontal sealing strips between adjacent stacked panels and by the vertical sealing strips between the ends of each panel and the frame.
