Description

History

Established in 1917.

the Hiram M. Chittenden Locks were official opened July 4 of that year. The U.S. Army Corps of Engineers constructed the locks to connect Lake Washington, Lake Union and Salmon Bay to the Puget Sound tidal waters, allowing recreational and commercial vessels to travel to the docks and warehouses of Seattle’s busy fresh water harbor.

Known locally as the Ballard Locks, after their northern Seattle neighborhood, the locks: maintain Lakes Washington and Union’s fresh water level at 20 to 22 feet above sea level; prevent mixing of sea water from Puget Sound with the lakes’ fresh waters; and move boats from the lakes’ water levels the Puget Sound, and vice versa (a boat elevator of sorts).

The complex includes two locks, a small (30×150 ft, 8.5×45.7 meters) and a large (80×825 ft, 24.4×251.5 meters); a fish ladder for migration of anadromous fish, notably salmon; a visitor’s center; and the Carl S. English, Jr. Botanical Gardens.
