Crews have entered the mop-up stage on the five-acre Willow Springs Fire in the Mill Creek area near The Dalles.  Rod Nichols of the Oregon Department of Forestry says quick response to the fire that was reported Wednesday morning was crucial to keep it small. ODF and other agencies put together several engines, two hand crews, and air support to fight the fire.  Nichols added conditions were such that had the fire gotten away, it could have become very large very quickly.  The fire was on a ridgeline that was at the northern edge of the Government Flats Fire two years ago.
