Description
Lock and Dam No. 9 is located on Mississippi River mile 647.9 near Lynxville, Wisconsin. Constructed and placed in operation in July 1937, the dam consists of a concrete structure 811 feet long with five roller gates and eight tainter gates. The earth embankment is 9,800 feet long with a grouted overflow spillway that is 1,350 feet long. The lock is 110 feet wide by 600 feet long. The lock is on the Wisconsin side of the river with a small parking area next to the lock where visitors can watch riverboats locking through. Several interpretive signs explain how the lock and dam system works.
