The Riverside Fire on the Mt. Hood National Forest in Clackamas County remains at 34% containment, and is 138,029 acres in size.  Officials say while the rain has moderated fire behavior, especially in open areas where grass and brush are the primary vegetation, it will not put the fire out.  Fire will continue to smolder under the tree canopy in heavier fuels like logs and stumps.  Firefighters have been taking advantage of the weather to search out and extinguish hot spots close to the fire perimeter.  Federal and state lands in the fire area remain closed.
