A small fire broke out on private lands near Highway 26, 10 miles south of Madras around 12:30 this afternoon. Lisa Clark with the Central Oregon Interagency Dispatch says they don't know how it started. "It’s actually under investigation. it did start fairly near the highway and we have investigators enroute. We’re working with Jefferson County Rural Fire District No. 1 on this. It looks like it may have started on private land before moving on to federal land." Clark says at last report, the fire burned about 10 to 15 acres, and firefighters will be watching for any winds that may kick up the fire. ODOT did close the highway for about an hour while crews worked on the blaze.
