Flood Impacts & Photos Collapse
If you notice any errors in the below information, please contact our Webmaster
36 Above 36 ft, expect widespread flooding, with serious flooding possible between Corvallis and Albany on the west bank of the river. At this and higher stages, the Willamette River between Harrisburg and Corvallis has historically been up to 3 miles wide.
32 Above 32 ft, expect flooding of low spots of Hwy 99 south of Corvallis, the Corvallis-Albany Hwy, and Hwy 34 near Corvallis.
30 Above 30 ft, expect extensive flooding of low-lying agricultural land east and south of Corvallis. Numerous secondary roads east of Corvallis are flooded at this level. Some streets in Corvallis may be flooded, including portions of Highway 34.
28 Above 28 ft, expect flooding of some river island access roads and secondary roads east of Corvallis.
26 At 26 ft, the river is at bankfull level and may spill out of its banks at some locations between Harrisburg and Albany.
