ABSTRACT:
An improved irrigation system. The irrigation system includes a primary canal, a secondary canal having enclosed ends such that a flow of water entering the secondary canal accumulates therein and eventually overflows unless a sufficient volume of water is removed from the secondary canal, a water metering unit for diverting water from the primary canal to the secondary canal, siphons for transferring water from the secondary canal to a field adjacent the canal, and apparatus for monitoring the level of water in the secondary canal and activating an alarm when water in the secondary canal rises past a selected level.
