It is now 30 days out from the great floods of 1996.
Some perspective is possible.
We have the following report published by the Bonneville Power Administration. The Corps reported that changes in Columbia and Willamette hydro system operations reduced the water level by seven feet at the Portland, Ore., Seawall. The Willamette River crested two inches below thetop of the seawall. . . . . Along the Columbia, the water level at Vancouver, WA was Seven feet lower. Ultimately, only a few levees on the lower Columbia River failed or were overtopped, and the total number of houses and farms flooded on the Columbia were modest in number.
