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:

Control room contact information is:

• Bonneville Lock and Dam (river mile 145): 541-374-8323
• The Dalles Lock and Dam (river mile 191): 541-506-8211
• John Day Lock and Dam (river mile 216): 541-739-1050

All vessel owners/operators lock through at their own risk. A personal flotation device is required for every member on board the vessel throughout the duration of the lockage. Follow the directions of the lock operator when using the locks or operating in the vicinity of the locks. The lock operator has final authority on the suitability of a craft for lockage. Please refer to the U.S. Army Corps of Engineers Safe Lockage Policy for Recreational Craft on the Columbia and Snake Rivers, published separately, for additional safety requirements.
