Close call at McNary Dam prompts safety warning for Columbia River boaters

UMATILLA — Federal officials are urging boaters to stay clear of restricted zones near dams following a close call on the Columbia River that forced engineers to alter dam operations to prevent a tragedy.

The U.S. Army Corps of Engineers, Walla Walla District, issued the warning after a disabled recreational boat drifted into a hazardous, restricted area near McNary Lock and Dam near Umatilla on Monday, July 6.

The incident triggered an immediate emergency response from district personnel, who temporarily altered spill operations for about 30 minutes. The adjustment was necessary to reduce dangerous surface spill flows and protect the stranded boaters. A USACE vessel deployed to the scene, safely reached the watercraft, and escorted the occupants out of the restricted zone. No injuries were reported.

While surface spills are used to support fish passage, officials emphasized they create highly turbulent and hazardous water conditions. A drifting or unpowered boat can easily be swept into spillway structures, where the severe danger is often hidden until it is too late to escape.

To prevent future accidents, the USACE reminds boaters to strictly observe all restricted zones above and below dams and ensure vessels are mechanically sound before launching. Officials recommend keeping a reliable anchor ready for immediate deployment and carrying oars or paddles as backup propulsion.

Boaters should also wear life jackets, stay alert for warning signs, and carry a marine radio to monitor local lock communications.

The USACE emphasizes that a disabled boat near a dam constitutes an immediate emergency, and boaters should call 911 right away without delay.
