A commercial tow enters Cheatham Lock during a major snow storm at the project in Ashland City, Tenn., Jan. 22, 2016. A dozen U.S. Army Corps of Engineers Nashville District employees were recognized for their actions to keep navigation locks and hydropower plants operating when rural roads were treacherous and made it difficult for personnel to report to work. Employees worked extra shifts, slept at projects, and braved the elements in some cases to keep producing hydroelectricity and commerce moving along the waterways in the Cumberland River and Tennessee River Basins.
