The present invention is an enclosed rain gutter for draining water from the surface of a sloped roof and conducting it to a down spout. The invention rain gutter includes a channel that is covered by collecting surface. The collecting surface has openings that divert water into the channel by using the surface tension property of water that causes water to adhere to a surface. While the collecting surface openings divert water into the channel, they also exclude debris from entering the channel and in particular they exclude debris that would be large enough to obstruct a down spout.
