Flood Impacts & Photos Collapse
34 ABOVE 34.O FT...EXPECT FLOODING OF MUCH OF DOWNTOWN VANCOUVER...ALONG WITH MAJOR FLOODING ALONG THE COLUMBIA RIVER FROM VANCOUVER DOWNSTREAM TO LONGVIEW. SOME LOWER LEVEES MAY BE OVERTOPPED.
31 ABOVE 31.O FT...EXPECT MAJOR FLOODING. OVERTOPPING OF SOME LOWER LEVEES IS POSSIBLE. EXPECT WIDESPREAD INUNDATION ALONG THE COLUMBIA FROM VANCOUVER DOWNSTREAM TO LONGVIEW. TRIBUTARY RIVERS WILL BE BACKED UP. MANY INDUSTRIES ALONG THE COLUMBIA AND MOST SHIP TRAFFIC WILL BE AFFECTED.
