CANAL LOCKS SECOND TO PANAMA
The Canal is about eight miles long from Puget
Sound to Lake Washington. It adds more than
ninety miles to Seattle's water frontage and gives
access for ocean shipping to the non-tidal fresh water
harbors of Lake Union, in the heart of the City,
and Lake Washington, twenty-five miles long and
four wide, on the east boundary of Seattle. The
right-of-way is 300 feet wide, the channel 100
feet wide, and the depth 36 feet. The locks are
capable of lifting larger vessels than any government
locks outside the Panama Canal. They are at the
Puget Sound entrance of the canal and form the
only barrier between the fresh water lakes, nine
feet above Puget Sound at high tide, and salt water.
The concrete walls are 55 feet high. 50 feet wide
at the base, and 8 feet at the top. The major
chamber is 825 feet long, 80 feet wide, and holds
a depth of 50 feet of water. The minor chamber
is 150 feet long and 30 feet wide. Ocean-going
craft go through the larger chamber in twenty
minutes and small craft through the smaller
chamber in five to ten minutes. The total cost of
the canal, including right-of-way, excavation, locks
and other features, was $5,000,000 borne by the
government, state, county and city,
