Discarded cars and a 19th Century Shipwreck are being discovered, human remains have been found, and barges are running aground as the Mississippi River has reached historic lows due to persistent drought throughout the Central U.S. 

Last Saturday, October 22nd, the river fell to a new low of -10.81 feet in Memphis, Tennessee. 

We speak with a scientist who studies water and rivers about what is causing the drop, the economic fallout, and what it spells for the future of the River in a climate change future.
