ABSTRACT:
An adjustable portable irrigation dam for use in an irrigation ditch is operative to selectively raise the water level upstream of the dam thereby permitting removal of water for irrigation of crops. The dam includes an elongated sheet support member extending transversely across the irrigation ditch and being rotatably supported in members selectively positioned on opposite sides of said ditch to resist forces thereon so that rotation of said support member will selectively raise and lower one end portion of a sheet of a flexible material into and out of blocking relation to the irrigation ditch. Retaining mechanism is connected to the sheet support member for selectively retaining the support member and the flexible sheet in a selected position.
