Abstract: An irrigation system innovating manual practices and method elevating channeled waters for a diversion to the land. A check means locating in the ditch cooperating with a metering valve means locating in the ditch bank for the regulation and distribution of waters to thereby produce and reproduce selective and known volumes. A ditch valve means automating a diversion through selective preset comprising a metering insert and conduit combination. A check means incorporating a movable lower panel portion of reduced area minimizing actuation loads depending from an upper stationary dam portion having a spillway elevating a mounting base for the location of controls and actuators, clear of checked waters. A check means balancing a diversion through lower panel manipulations, while providing for the controlled release of accumulated water. A check means flexible by degree to automating combinations of actuators, timers and remote control, while incorporating portability for multiple use and storage.
