100 years ago, Seattle and US Army Corps of Engineers joined forces to create a Commercial Navigation Route to Develop Seattle.
Today, the Locks contribute over $1.2 Billion/yr. to the Seattle economy and are the Nation's busiest with over 40,000 vessels/yr.
Boats 'lock thru' 24 hours/day, except during maintenance.
In addition, significant salmon runs pass through the Locks and Fish Ladder that can exceed 150,000 adult salmon per year.
The Locks primary mission is commercial navigation.
Federal funding is based on Value of commercial cargo, which is a small percentage of actual needs.
However, Visitor educational facilities require local support and is being provided by the non-profits
Corps of Engineers Foundation and Discover Your Northwest.
