ABSTRACT:
A device for creating a specific but temporary aquatic passage in an artificial or natural river. The device includes bases which rest on the bottom of a river and elements which extend upwardly from the bases. The bases have holes formed therein which receive rods that extend downwardly from the elements. Placement of the bases in the river bed, and subsequent installation of elements into the bases, allows obstacles to be created in the river which are desirable for canoeing and kayaking.
