Abstract

A fence for a depressed waterway has a pair of anchor posts normally located on opposite sides of the waterway. At least one ground anchor is positioned between the anchor posts in the bottom of the waterway. A wire fence extends between the anchor posts and over the ground anchor. A vertical post is secured to the wire and is suspended by the wire above the ground anchor. The vertical post has a lower end detachably secured to the ground anchor so that the lower end of the vertical posts will disengage the ground anchor and will tilt on said wires in a downstream direction when encountered by debris under flooded conditions. The method of use of a waterway fence comprises placing opposite fence anchor posts on opposite sides of the waterway. At least one ground anchor is placed in the waterway below the normal vertical plane of the fence to be built. The fence wire extends between the anchor posts and over the waterway. A vertical post is secured to the wire above the ground anchor and is suspended by the wire, and is detachably secured by its lower end to the ground anchor. The lower end of the suspended post disengages the ground anchor and tilts in a downstream direction when impacted by debris under flooded conditions. The suspended post is held in its detachable connection with the ground anchor by the spring tension in the fence wire.
