The Central Oregon Interagency Dispatch Center says the Oak Canyon Fire along the Wasco/Sherman County line north of Highway 216 is now mapped at 15,000 acres, and is at 25% containment.  The dispatch center said air resources were very effective on Tuesday.  Four helicopters, one air attack, and four fire bosses and scoopers were used in the suppression effort.  The center also said all containment lines are holding.  Additional engines and a hotshot crew have been ordered.  Two outbuildings were damaged by the fire.  The Wasco County Sheriff’s Office on Tuesday issued a Level 1 “Be Ready” evacuation advisory from the Tygh Ridge/Highway 197 intersection directly due east to 60833 Tygh Ridge Road to include Hulse Road.   That joined advisories issued Monday including placing all of Conroy Road up to 1 mile east and the west side of Conroy Road north of Highway 216 on Level 3 “Go Now” evacuation alerts.   The Macks Canyon Recreation Area on the Deschutes River is also at Level 3.   Level 2 “Get Set” evacuation advisories are in place from the Canyon Road and Highway 216 junction due east to the Deschutes River and south to Oak Springs Road to the Deschutes, and milepost 1 to milepost 3 on the north side of Highway 216.  The Bureau of Land Management has closed all of the land it administers on the east side of the Deschutes River from the intersection of the Lower Deschutes Access Road and Highway 216 downstream to Macks Canyon, and on the west side from Oak Springs Fish Hatchery downstream to Craft Canyon.   All boating in segment 3 of the Deschutes River is closed, while it is allowed from segment 4 but with no launching from the Macks Canyon boat ramp.
