A wicket gate for providing a dam in a navigable waterway is described. A wicket gate is connected at one end to an axle which permits rotation of the wicket gate from a horizontal to a vertical position. The axle is supported on first and second carrier bearing, connected to a concrete sill within the navigable waterway. The wicket gate may be raised and lowered by a motor located within a gallery of the concrete sill. The motor is connected via a drive shaft to the axle of the wicket gate. This structure permits movement of the gate without props or other protrusions which could collect and hold debris.
