The Locks Proper
As noted above, the complex includes two locks. Using the small lock when boat traffic is low conserves fresh water during summer, when the lakes receive less inflow. Having two locks also allows one of the locks to be drained for maintenance without blocking all boat traffic. The large lock is drained for approximately 2-weeks, usually in November, and the small lock is drained for about the same period, usually in March.
The locks can elevate a 760-by-80-foot (230 m × 24 m) vessel 26 ft (7.9 m), from the level of Puget Sound at a very low tide to the level of freshwater Salmon Bay, in 10–15 minutes. The locks handle both pleasure boats and commercial vessels, ranging from kayaks to fishing boats returning from the Bering Sea to cargo ships. Over 1 million tons of cargo, fuel, building materials, and seafood products pass through the locks each year.

Famous quotes containing the words locks and/or proper:
“So Lycidas sunk low, but mounted high
Through the dear might of him that walk’d the waves,
Where other groves and other streams along
With nectar pure his oozy locks he laves
And hears the unexpressive nuptial song
In the bless’d kingdoms meek of joy and love.
There entertain him all the saints above
In solemn troops and sweet societies,
That sing, and singing in their glory move,
And wipe the tears for ever from his eyes.”
—John Milton (1608–1674)
“The Methodists love your big sinners, as proper subjects to work upon.”
—Horace Walpole (1717–1797)
