Waterways Experiment Station Dam

The Waterways Experiment Station, also known as WES-Original Cantonment in Vicksburg, Mississippi, is a sprawling complex built in 1930 as a United States Army Corps of Engineers research facility. Its campus is the site of the headquarters of the Engineer Research and Development Center (ERDC) of the Corps of Engineers. WES is the largest of the four Corps of Engineers' research and development laboratories. The facility was listed on the U.S. National Register of Historic Places in 2000 in part for its architecture. The listing was for a area roughly bounded by Spillway, Durden Creek, Tennessee Rd., and Dam Spillway, in Vicksburg, with five contributing buildings and three contributing structures.
