Hydra - LOPAC - Water Control Gate

The LOPAC gate was developed by Peter Langemann in the 1980s to assist tail end irrigators in managing widely fluctuating water supplies. A number of installations have operated successfully for the past couple of decades. Aqua Systems 2000 Inc. (AS2I) has combined the simplicity of the LOPAC with a hydraulic actuator to provide a flexible and economical solution to water control problems in small to medium sized canal.
