Table of Contents
The Coast Guard is enforcing a temporary security zone on the Willamette River in Portland. The zone covers all water from the surface to the riverbed between the Hawthorne and Steel Bridges. It runs from noon on June 2, 2026, through noon on June 8, 2026.
Why it matters: The restriction exists to keep festival vessels and spectators safe during a crowded public event. For most boaters, it means rerouting around the downtown river section for one week. The Coast Guard handles the enforcement, so compliance is straightforward: stay out unless you get clearance.
