According to Coast Guard officials Thursday, Dec. 27, 2012, the Mississippi River level is dropping again and could get so low as early as next week that some barge operators will stop operating. But a Guard official remains confident that the nation's largest waterway will remain open to traffic despite the worst drought in decades. (AP Photo/Jeff Roberson, File)
