Abrégé

Aquatic curtain devices and methods for forming waterway channels and reducing waterway maintenance are disclosed. Each curtain device comprises an elongated float and an elongated flexible curtain depending from a first side of the elongated float. The curtain has a bottom end with a weight extending along the entire length of the elongated float. The float is configured to be sufficiently buoyant to support the curtain in an upward direction. Each curtain device is configured for the curtain to remain in a substantially taut state when in use and accommodate fluctuations in water levels, such that the elongated weight remains on the bottom of the waterway while the elongated float remains on the surface. Artificial channels are constructed by selecting the length of the elongated float to achieve the desired channel dimensions using two or more curtain devices positioned along a desired path in a waterway.

Abrégé

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.
