PORTLAND, Ore. – Recreational boaters passing through the three lower Columbia River dams must follow a summer locking schedule through Sept. 14. Commercial vessels will continue to lock through upon arrival except during the times specified for recreational vessels.

Lock operators may use their discretion to allow recreational vessels to pass through with commercial craft. The U.S. Army Corps of Engineers may consider special lockages outside the scheduled times for flotillas or other unique events sponsored by yacht clubs, marinas, and other groups. However, users must provide advance notice of at least 24 hours to ensure the appropriate operations manager, or their designated representative, has time to arrange the lockage.

The lock schedules are as follows, in effect now through Sept. 14:

Upstream	9 a.m. noon 3 p.m. 6 p.m. 9 p.m.	9 a.m. noon 3 p.m. 6 p.m. 9 p.m.	9 a.m. noon 3 p.m. 6 p.m. 9 p.m.

The Columbia-Snake inland navigation system, which stretches 360 miles from Portland, Oregon, to Lewiston, Idaho, provides critical benefits to business and the public. Approximately 9 million tons of cargo valued at over $3 billion is barged on the Columbia-Snake River System annually. The navigation system contributes jobs, facilitates import and export trade, and benefits the economy, environment, and quality of life in the Pacific Northwest.
