To prevent diversion of Mississippi River at Old River, control structure, enlarged levees, and navigation lock are under construction; combination of shallow wellpoints and deep well pumps, installed less than 2000 ft from banks of river, is keeping 40-acre excavation dry; cut to depth of 90 ft below high river level, hole will serve as foundation for new low sill control structure.
