General / Hazards To Navigation / Obstructions
A sunken barge has been reported in Columbia Cut immediately forward of the Delta Farms Reclamation District No. 2030 levee, near the Clavius Club. The barge reportedly sank in early 2023 and is located in navigable water within a posted no-wake zone frequented by recreational and marina traffic. The submerged hull, projecting spuds, and partially exposed equipment may present a hazard to navigation. Mariners are advised to maintain a sharp lookout and transit the area with caution.
