ABSTRACT:
Artificial "seaweed" or "reefs" for installation on the bottoms of lakes or the like to build up sandbars to reclaim beaches and reclaim coastal land has elongated hollow tubes partially filled with sand, silt or other lake bottom material to lie stationary on the lake bottom in spaced side-by-side relation at a selected orientation relative to the shore line and connectd by anchor means for buoyant sheets or ribbons which will float upright in the water to trap sand and sediment for building up sandbars and reefs on the lake bottom. In one embodiment, the side-by-side hollow tubes are formed along the side edges of a wide sheet of plastics material which is slit at selected intervals and the buoyant sheets or ribbons are threaded through these slits providing a pair of upstanding buoyant legs in spaced relation. In another embodiment, the tube connected by strands or filament receiving looped ends of the buoyant sheets or ribbons in end-to-end relation. The "seaweed" or "reef" is conveniently deployed from a travelling boat or barge which fills the tubes with sand or sediment as they are lowered into the water.
