An automated skimming flow perimeter gutter control system for swimming pools is provided having a water cleaning and recirculation system receiving water from the pool, cleaning it, and returning it to the pool; a gutter conduit for disposition about the perimeter of a swimming pool, receiving overflow across a top edge thereof and adapted to carry water at a level below a predetermined level in the swimming pool; a drain line connecting the gutter conduit with the water recirculation system; suction means in series flow connection with the gutter conduit and drain line for positive withdrawal under suction of water from the gutter conduit and feed of such water to the water recirculation system for return to the pool; at least one of (a) means for controlling water recirculation capacity to accommodate any selected flow of water from the gutter to the water recirculation system; and (b) means for controlling suction flow from the gutter to the water recirculation system; and at least one water level-responsive sensor sensing and directly responding to the level of water in the gutter conduit by adjusting at least one of the means controlling water recirculation capacity to accommodate flow from the gutter and the means for controlling suction flow, to increase gutter drain flow sufficiently to prevent gutter water flooding back from the gutter to the pool.
