Flood Impacts & Photos Collapse
If you notice any errors in the below information, please contact our Webmaster
30 Above 30.0 ft, Expect flooding of downtown Portland from Park Ave east to the Willamette and north of Burnside. Historically, Union Station begins to flood at this point and rail traffic will likely be impacted. Expect flooding of Oaks Park, along with moorages and industrial areas from Oregon City through downtown Portland into industrial NW Portland.
28.8 At 28.8 ft, Expect the river level to reach the top of the lowest point of the downtown Portland sea-wall. Flooding of some portions of Waterfront Park is possible at this and higher stages.
27 Above 27.0 ft, Expect flooding of Front Street near the Burnside Bridge.
