MULTNOMAH COUNTY, Ore. — One woman was killed and four others were injured after a boat crashed into a dock structure on the Willamette River late Saturday night, according to the Multnomah County Sheriff’s Office.
The crash was reported at approximately 11:24 p.m. on July 4, 2026, when the Bureau of Emergency Communications received a 911 call that a boat had run ashore in the 14900 block of Northwest Gillihan Road on Sauvie Island.
Emergency crews from the Sauvie Island Fire District, American Medical Response, and the Multnomah County Sheriff’s Office responded to the scene.
Upon arrival, first responders found one woman deceased. Four additional occupants, including the operator of the vessel, were transported to area hospitals with injuries that authorities said are not considered life-threatening. Investigators believe all five people aboard the boat were adults.
According to the preliminary investigation, the vessel, a 33-foot cabin cruiser, struck a section of an aluminum walkway leading to a dock that was supported by several large vertical pilings.
Investigators are still working to determine what caused the crash. Officials said it is too early to determine whether speed, impairment, or lighting conditions played a role in the incident.
The identity of the woman who died has not been released pending notification of her next of kin.
Detectives with the Multnomah County Sheriff’s Office Investigations Unit are leading the investigation in coordination with the Multnomah County District Attorney’s Office.
Authorities emphasized that the information released is preliminary and may change as the investigation continues. No photographs from the scene have been made available.MULTNOMAH COUNTY, Ore. – The Multnomah County Sheriff’s Office is investigating a deadly Fourth of July weekend boating crash on the Willamette River.
