This is the final April 9, 2022 dredging map from HDR engineering showing Rigid Contractor’s last dredging effort to open the mouth of the San Bernard River to the Gulf of Mexico. The project was started on July 19, 2021 and ended April 14, 2022. Buildup of sediment related to lack of flow from San Bernard watershed during the drought was the county’s reason.
