Bayou Teche (Louisiana French: Bayou Têche) is a 125-mile-long (201 km)[1] waterway in south central Louisiana in the United States. Bayou Teche was the Mississippi River's main course when it developed a delta about 2,800 to 4,500 years ago. Through a natural process known as deltaic switching, the river's deposits of silt and sediment cause the Mississippi to change its course every thousand years or so.
