The Hiram M. Chittenden Locks, or Ballard Locks, is a complex of locks at the west end of Salmon Bay, in Seattle, Washington's Lake Washington Ship Canal, between the neighborhoods of Ballard to the north and Magnolia to the south. The Ballard Locks carry more boat traffic than any other lock in the US, and the Locks, along with the fish ladder and the surrounding Carl S. English Jr. Botanical Gardens attract more than one million visitors annually, making it one of Seattle's top tourist attractions.
