For those looking for gizzad shad on the potomac, this area has been good for me the last 2 weeks. Set your net in about 3' about 50 yared off the rip rap closest to high point Occoquan bay. It drops from about 3 to 5'. been catching 20 shad in 8 to 10 min soak within a few hours of high tide. another good spot is in pohick bay. set net from about 25yards off the duck blind on the point shown on the map.
