A beaver controlling culvert attachment prevents beavers from disturbing the flow of water through a culvert. An upstream unit includes a vertical pipe having an upper grate which prevents the entrance of beavers and debris, while allowing the entrance of water during periods of high water levels. A horizontal pipe has an upstream end attached to an upper portion of the vertical pipe and a downstream end attached to an upstream end of the culvert by an attachment plate. A basket insert is carried within the vertical pipe, and is movable between an in-use position, wherein a grate prevents entrance to the bottom of the vertical pipe, and a clean-out position wherein the grill is elevated to allow disposal of accumulated debris through the horizontal pipe and culvert. A downstream grate prevents beavers from entering the downstream end of the culvert, and from filling the culvert with debris.
