Abstract: A waterfowl decoy anchor for anchoring a floating decoy in a lake or stream for attracting waterfowl to a hunting site or blind. The anchor is typically tied to an eyehole in the lengthwise keel of a decoy by means of a connecting cord having a desired length. The anchor includes an elastic cord segment of latex connected at one end to a “D”-ring for attachment of the connecting cord and, at the other end, to an anchor ball of lead or iron. The other end is threaded through the anchor ball and knotted at the end, the knot being drawn back into a knot cavity within the ball. A cap covers the knot cavity and the ball is sealed up to the tubing with vinyl plastic or rubber, avoiding water pollution and corrosion of the ball. The connecting cord and anchor is wound around the keel for storage.
