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.  The construction of the locks profoundly reshaped the topography of Seattle and the surrounding area, lowering the water level of Lake Washington and Lake Union by 8.8 feet (2.7 m), adding miles of new waterfront land, reversing the flow of rivers, and leaving piers in the eastern half of Salmon Bay high and dry. The Locks are listed on the National Register of Historic Places and have been designated by the American Society of Civil Engineers as a National Historic Civil Engineering Landmark.

Lake Washington salmon have been counted each year since 1972 as they enter freshwater at the Hiram M. Chittenden Locks -- also known as the Ballard Locks -- on Seattle's Lake Washington Ship Canal. Currently, the Washington Department of Fish and Wildlife and Muckleshoot Indian Tribe staff conduct the counts cooperatively to determine if there are sufficient sockeye to open fishing seasons.

Sockeye counts begin on June 12 each year and go through July in order to provide consistent data from year to year. The sockeye are counted daily during set time periods as they pass through both the locks and the fishway, and the counts are converted into a daily total number of fish passing upstream. In early July, state and tribal managers begin to make weekly projections of the expected total run size based on the current counts. When the co-managers expect the total run size includes sufficient surplus fish above the escapement goal of 350,000 sockeye, sport and tribal fishing seasons will be opened.
