  • Patent number: 7114878
    Abstract: An irrigation gate system installed in a channel (such as a ditch or canal) for controlling the flow of water through the channel maintaining a desired level of water upstream from the irrigation gate system or for controlling water flow downstream from the irrigation gate system. The irrigation gate system includes a gate which is maintained in a closed position for preventing water flow past the gate or alternatively, in one of a plurality of open positions for allowing desired amounts of water in the channel to flow past the gate. The gate is vertically hingedly connected to a pipe shaft supported by a frame installed in the channel. A gate actuator moves the gate between its various positions upon receiving signals from an electronic programmable controller which in turn may receive signals from a variety of sources.
