This invention comprises laminar flow generation devices that are adapted to be affixed to the upper, substantially flat surfaces of a rain gutter deflector system. They have at least one water diverting surface which rises abruptly from such upper surface and provides for the smooth redirection of water from the region of its top end through an angular displacement preferably not in excess of 90 degrees to the other of its ends from which the water is discharged. Embodiments may have two such water diverting surfaces with a common leading edge to divide the water and redirect the resulting flows away from each other. They may be further adapted for affixation to gutter deflector surfaces which intersect each other at an angle, as at the site of a roof valley. The diverting surfaces may include apertures to provide flow paths for water to further reduce the volume of the water discharged at the egress end of the diverting surfaces.
