Texas City Dike Shipwreck Salvage

Lost Treasure TX • Galveston County County
Description
Modern salvage lore along the five-mile Texas City Dike — routine dredging and storms expose timbers, fittings, and occasional cargo from nineteenth- and twentieth-century wrecks in the Galveston Bay entrance.
Historical Notes
The Texas City Dike extends into Galveston Bay from the Texas City Refinery district, paralleling the ship channel. The City of Texas City and port authorities maintain the structure; dredging periodically uncovers wreck material. Social media and local news have reported crews finding ship timbers and artifacts during dike maintenance. Treasure hunters associate the area with Lafitte-era wrecks, Civil War runners, and storm-sunk fishing boats carrying cash and equipment. Most finds are archaeological rather than bullion. Coordinates mark the dike root near Texas City; the dike extends several miles into the bay.
