Wikipedia (
visit link) tells us this about the fish ladder at this site:
"A fish ladder is integrated into the locks for migration of anadromous fish, notably salmon." There is also a sculpture called "Salmon Wave" above the fish ladder site.
Wikipedia also informs us about the Locks:
"The Hiram M. Chittenden Locks is a complex of locks that sits at the west end of Salmon Bay, part of Seattle, Washington's Lake Washington Ship Canal. They are known locally as the Ballard Locks after the neighborhood to the north. (Magnolia lies to the south.)
The locks and associated facilities serve three purposes:
To maintain the water level of the fresh water Lake Washington and Lake Union at 20–22 feet (6.1–6.7 m) above sea level (Puget Sound's mean low tide).[citation needed]
To prevent the mixing of sea water from Puget Sound with the fresh water of the lakes (saltwater intrusion).
To move boats from the water level of the lakes to the water level of Puget Sound, and vice versa.
The complex includes two locks, 30 ft × 150 ft (9.1 m × 46 m) (small) and 80 ft × 825 ft (24 m × 251 m) (large). The complex also includes a 235 ft (72 m) spillway with six 32 ft × 12 ft (9.8 m × 3.7 m) gates to assist in water-level control... The grounds feature a visitors center, as well as the Carl S. English, Jr., Botanical Gardens.
Operated by the U.S. Army Corps of Engineers, the locks were formally opened on July 4, 1917, although the first ship passed on August 3, 1916.[13] They were named after U.S. Army Major Hiram Martin Chittenden, the Seattle District Engineer for the Corps of Engineers from April 1906 to September 1908.[9] They were added to the National Register of Historic Places in 1978."
