The term batture, recorded in English as early as the mid–nineteenth century, is French and in the lower Mississippi River basin most often refers to the elevated riverbed between levees. It is well known that the streets of New Orleans, for example, lie lower than the surface of the Mississippi. Only the levees, when they hold, prevent the river within the batture from flooding the city and surrounding countryside. Batture is also used in Louisiana to denote solid ground between low water on a river and parallel levees, and less often refers to a seabed raised, by floor shifting and deposits, above the surface of the water.
