Chuck Hayes, supervisory wildlife biologist with the U.S. Fish and Wildlife Service, speaks with Col. Thomas J. Tickner, commander of the U.S. Army Corps of Engineers, during a visit to the Savannah National Wildlife Refuge, Aug. 19, 2013. Established in 1927 and operated by the U.S. Fish and Wildlife Service, the refuge provides more than 29,000 acres of freshwater marshes, tidal rivers and bottomland hardwood habitat. The Corps has performed several projects for the refuge, including a series of freshwater control structures completed in 2010. As a federal partner, the Corps often consults with the FWS when making water management decisions affecting the Savannah River Basin. The FWS is also a cooperating federal agency in the Savannah Harbor Expansion Project.
