The water control gauge is a cylindrical reservoir for collecting water from rain, sprinklers and other airborne sources. The reservoir has a float measurer to measure the level of water collected in the reservoir. A pulley having a float detects the water level and the turning of the wheel of the pulley operates an electric switch to allow or inhibit the operation of a sprinkler system. A siphon is attached to the reservoir to drain the water once a predetermined level has been reached.
