this is the water channel between lake washington and the puget sound in seattle. the locks (visible in the distance) allow boat traffic to traverse this cut.

Photos from a walk around the Hiram Crittenden Locks (locally known as the Ballard Locks) in Seattle, Washington.
From the US Army Corps of Engineers website:
The complex of locks sit in the middle of Salmon Bay and are part of Seattle's Lake Washington Ship Canal. They are known locally as the Ballard Locks after the neighborhood to their 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 to 22 feet above sea level.
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, a small (30 x 150 ft, 8.5 x 45.7 meter) and a large (80 x 825, 24.4 x 251.5 meter). The complex also includes a (235-foot, 71.6 meter) spillway with six (32 x 12-foot (3.7 m), 9.8 x 3.7 meter) gates to assist in water-level control. A fish ladder is integrated into the locks for migration of anadromous fish, notably salmon.
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. 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. They were added to the National Register of Historic Places in 1978.
A sunny day pulled me out of the house and down to the Ballard Locks late this afternoon. This place never fails to deliver amazing photo opportunities.

The Hiram M. Chittenden Locks are a complex of locks that sit in the middle of Salmon Bay, part of Seattle's Lake Washington Ship Canal. They are known locally as the Ballard Locks. This is the location of the popular viewing windows at the fish ladder.
Salmon and steelhead hatch and partially grow up in rivers and streams. Then they journey to sea where they spend most of their adult lives. Near the end of their life cycle, the few that have survived journey back from the sea to spawn in the streams where they were hatched years before.
Even in 1917, the U.S. Army Corps of Engineers understood the importance of fish passage facilities. They constructed a 10-step ladder to the south of the spillway dam. In 1976, a new ladder was built to reflect modern fish ladder standards and the amount of attraction water was increased. Today's ladder has 21 steps, or weirs, which allow the fish to swim upstream on a gradual incline.
Sockeye, chinook, and coho salmon, as well as steelhead, migrate through the ship canal back to Lake Washington and its tributaries. Six lighted windows in the fish viewing room provide visitors with an underwater view of the migrating fish in the elongated 18th step. Attraction water (water moving swiftly in a direction opposite the fish) helps fish find the ladder. An underwater conduit drains salt water from the basin at the upstream end of the large lock into the ladder. The salt water mixes with the fresh water from the lake, providing an abundance of attraction water and an area for the fish to gradually adjust to fresh water.

Seattle, Washington
The Hiram Chittenden Locks will be 100 years old in 2017, one of Seattle's top tourist destinations and a local favorite.
The "Ballard Locks", as they are known locally, connect fresh and salt waters, holding back the flood of an enormous water basin (Lake Union, Lake Washington and Lake Sammamish).
The fish ladder at the locks provides access for large runs of salmon returning to their native streams along with a front-row seat for the people of Seattle and visitors to watch them and the sea lions who prey on them.
The drawbridges around Ballard are reputed as some of the world's busiest because of boat traffic (commercial and leisure) transiting between the fresh and salt waters connected by the Ballard Locks. The average time for a drawbridge to open and close is about 4 minutes and quite a sight. The drawbridges do not open between 7-9 AM or between 4-6 PM on weekdays.
The bridges are opened and closed by the bridge tender who communicates with vessels from a high perch with a prime view.
