ABSTRACT:
An automatic culvert directional flow control device comprising a flange or support ring supporting a hinge assembly. A pair of dampers are joined to the hinge in a pivoting and a vertical relationship, one over the other. The dampers are held in a normally closed position by means such as a counter balance. The culvert directional flow control device is designed for easy installation on the inside of existing culverts and acts to prevent water from reversing direction of flow through the culvert against the desired normal flow.
