Past Debris Events

White River

A massive debris flow and sudden changes to the paths of several rivers on the east side of Mt. Hood severely damaged Highway 35 on Nov. 6 and 7, 2006. The washed away sections of the highway were rebuilt under emergency repairs. The road reopened on Dec. 8, 2006.

Clark & Newton Creek

In November 2006 storm events caused severe debris flow damage Clark Creek, and Newton Creek. These storm events caused the complete closure of Highway 35 during peak recreational times in the Mt. Hood National Forest. This type of repair is a “betterment”, defined as an added protective feature, such as the relocation or rebuilding of roadways at a higher elevation or the extension, replacement or raising of bridges, and added facilities not existing prior to the natural disaster or catastrophic failure such as additional lanes, upgraded surfacing, or structures.
