A fire south of Dufur on Tuesday afternoon burned about four acres and forced Level 3 evacuations for a time before its forward progress was stopped.  The Wasco County Sheriff’s Office says the fire was first reported around 3:10 p.m. in the area between upper Fivemile Rd., Valley Dr., and Ridgetop Rd.  Fire bosses were brought in to provide aerial support to crews from Dufur, Wamic, Tygh Valley, and the Central Oregon District of the Oregon Department of Forestry.  Forward progress was stopped around 5 p.m., with one structure lost.  Level 3 “Go Now” evacuations were issued for all of Sportsman’s Paradise, Upper Fifteen Mile Rd to Dufur Valley Rd and all of Ridgetop Rd, but that was reduced to Level 2 by the early evening.  There is no cause of the fire at this time.
