The Microwave Tower Fire five miles west and southwest of Mosier is now at 53% containment, while the size is now at 762 acres.  The Great Basin Interagency Incident Management Team and the Oregon Department of Forestry said Friday that most of the southern fireline is now contained.  On the northeast side, successful firing operations are helping secure lines, and firefighters will continue them today, utilizing the dozer line, the Columbia River Highway State Trail, and rocky areas, tying it in with the fire that has already reached the trail, securing it all the way from east to west.  Fire officials say the operations will increase smoke and may make flames visible.  The fire is showing low to moderate activity with creeping, smoldering, and backing downslope toward containment lines.   The Wasco County Sheriff’s Office said that evacuation levels would remain in place today.
