Flood — Clackamas, Oregon
2006-11-07 · near Bull Run, Clackamas, Oregon
Event narrative
The Sandy River near Bull Run crested at flood stage of 19.3 on November 7th.
Wider weather episode
Several days of nearly non-stop weather systems brought copious amounts of rainfall to northwest Oregon. With moderate temperatures in place, very close to all of this rainfall became run-off, and many rivers over the area swelled in response. Many rivers reached and maintained flood stage for a couple days.
One river in particular, the Wilson River near Tillamook, recorded record flooding. This river's flood stage is 12.0 feet, and the river crested at 22.8 feet (38,500 cfs), well above major flood stage. The town of Tillamook, downstream from this gauge, was underwater for several days after the crest.
