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.

An approach to restoring and protecting a canal divider wall includes positioning a precast panel over the wall in the channel with an inner cavity of the precast panel; installing a titanium bolt through the precast panel and the wall in the channel; and pumping a polymer grout through a bore defined in the cap.
