USACE urges boating safety near dams

The U.S. Army Corps of Engineers, Walla Walla District reminds boaters to stay clear of boat restricted zones near dams after a disabled recreational boat drifted into the restricted area near McNary Lock and Dam on Monday, July 6.

The incident required district personnel to initiate an emergency response and temporarily alter spill operations for approximately 30 minutes to reduce hazardous surface spill flows and prevent loss of life. A district vessel deployed to assist, safely reached the stranded boaters, and escorted them out of the restricted area. No injuries were reported.

While surface spill operations support fish passage, they create highly hazardous flow conditions. A disabled or drifting boat can easily be swept toward spillway structures, where the danger may not be visible until it is too late to safely maneuver away.

Boating Safety Reminders:

• Observe restricted areas: Never enter designated boat restricted zones above or below dams.
• Maintain your vessel: Ensure your boat is mechanically sound to prevent engine failure in swift currents.
• Be ready to anchor: Keep a reliable anchor ready for immediate deployment to prevent drifting if your vessel loses power
• Keep manual propulsion onboard: Have a backup oar or paddle to navigate to shore if the engine fails.
• Wear life jackets: Ensure all passengers wear properly fitted life jackets.
• Stay alert: Maintain a lookout for hazards, buoys and warning signs.
• Understand water conditions: Know your boat’s handling capabilities in swift, turbulent waters.
• Equip a marine radio: Ensure you can summon emergency help and receive weather alerts in areas without cellular coverage. Monitor VHF Channel 14 for local lock-related communications. Walla Walla District lock callsigns include:
  • McNary – WUJ 41
  • Ice Harbor – WUJ 42
  • Lower Monumental – WUJ 43
  • Little Goose – WUJ 44
  • Lower Granite – WUJ 45

Because a disabled or drifting boat near a dam is an immediate emergency, boaters should call 911 right away. Do not delay callouts to wait for friends or to see if conditions worsen.
