Everyone in the vessel must be wearing a personal floatation device throughout the duration of the lockage. All vessel owners and operators lock through at their own risk and must comply with the Corps’ safe-lockage policy. Portland District’s navigation information and the brochure "How to Lock Through" is available at www.nww.usace.army.mil/Portals/28/docs/navigation/locking.pdf.
Nine million tons of commercial cargo, valued around $3 billion, is transported through the lock system each year, according to navigation industry data. The Columbia-Snake navigation system is part of a larger waterborne commerce system that is vital to the economic health of the Pacific Northwest. This import/export gateway allows river transport 465 miles inland from the Pacific Ocean to Lewiston, Idaho.
