2020 Winter Flood Damage and Repair

Background/Overview

On Feb. 6, 2020, the Pomeroy and Walla Walla Ranger Districts of the Umatilla National Forest experienced substantial road and trail damage from region-wide flooding across northeast Oregon and southeast Washington. Flood damage is significant and the forest has implemented long-term temporary closures along the Umatilla River, South Fork Walla Walla River and Tucannon River until critical repairs can be completed. Ground access is restricted to affected areas due to the many miles of damaged county roads.  The Umatilla National Forest conducted an aerial reconnaissance flight on Monday, Feb. 10, 2020, to get a preliminary assessment of flood damage.  Forest staff are currently working on options to secure funding and resources to conduct repairs.  Until those repairs can be completed, damaged areas are closed for public safety.
