Irrigation gate system

An irrigation gate system installed in a water canal for controlling the flow of water in the canal comprising:

• a. at least two opposed rotateable pipe shafts positioned near the water canal;
• b. a gate hingedly connected to each pipe shaft, the gates for moving between a closed position for preventing water upstream of the gates from flowing past the gates and a plurality of open positions to allow variable amounts of water to flow past the gates;
• c. a gate actuator for rotating both pipe shafts thereby rotating the gates between positions;
• d. a controller in communication with the gate actuator for providing signals to direct the gate actuator to rotate the gates between positions by rotating the pipe shafts;
• e. a sensor in communication with the controller for providing the sensor's readings to the controller;
• and
• f. the controller calculating the difference between the readings provided by the sensor and a pre-programmed condition stored in the memory of the controller and providing signals to the gate actuator based on the difference between the sensor readings and the pre-programmed condition.
