In mid-May of 2011 the Columbia River began to approach flood stages from the combination of melting snow in the mountains and an exceptionally rainy spring. On June 2, 2011 the high water peaked at 22.7 feet, causing minor flooding in Multnomah and Clark Counties.

The local drainage districts were in enhanced emergency operations for over a month as the river levels increased, peaked, and slowly returned to more normal elevation.
