Abstract
A method of forming a maintenance free channel is disclosed. The method consists of positioning a plurality of curtain devices along a desired path in a waterway. The curtain devices each consists of an elongated float and an elongated flexible curtain depending from a first side of the elongated float. The elongated curtain has a bottom end with a weight extending along the entire length of the elongated float. The elongated float is configured to be sufficiently buoyant to support the curtain in an upward direction. The length of the elongated float is selected to equal a desired length of the channel. The height of the elongated flexible curtain is selected to be approximately equal to the depth of the waterway such that the elongated weight remains on the bottom while the elongated cylindrical float remains on the surface.
