A rain cover 10 prevents leaves and other debris from plugging a conventional gutter G, while rain water from the roof of a building is transmitted to the gutter by surface tension. The cover includes a main plate 14 inclined for allowing water and debris to pass by gravity from an upper portion 30 to a lower portion 32. A front portion 16 of each of a plurality of traversely spaced fins 14 extend laterally beyond an outer wall of the gutter. Pairs of adjacent fins 14 are separated by a uniform traverse gap of less than 0.05 inches to significantly increase the return of water to the gutter by surface tension with the fin walls. The cover may be economically manufactured from plastic or metal, and may be easily installed on an existing gutter system. The separation device of the present invention may be used in other applications to separate solid debris from a fluid.
