The Olmsted Locks and Dam project, which is replacing two older locks 52 and 53, will bring reliable navigation to the Ohio River offering millions of dollars of economic gains annually. Olmsted Locks and Dam is the largest Corps project since the Panama Canal. It consists of two 110-foot by 1,200-foot locks, located adjacent to the Illinois bank and a dam comprised of five tainter gates which control the amount of water that flows downstream. Additionally, there are 140 wickets and a fixed weir.
