August 04, 2010

Sheriff Mike Harum reports on August 4, 2010 at approximately 6:15 a.m., the Chelan County

Sheriff’s Office was notified of a mud slide on Highway 97A at mile post 207 ½. A thunderstorm rain cell dumped

rain in the Tenas George Canyon and the rain water rushed down the canyon carrying large rocks, mud, trees and

debris across Highway 97A, over Burlington Northern Railroad tracks and into the Columbia River.

A single

family mobilehome was damaged and the residents were taken to safety, un-injured. Washington State Patrol (WSP)

and the Department of Transportation (DOT) arrived on scene and closed the highway until further notice. A DOT

supervisor believed Highway 97A would be closed for a minimum of 24 hours. DOT supervisor and engineers will have

to wait until the mud flow literally stops flowing before they can legitimately access the damage to begin clean
