(Niagra, OR)  --  A group of five people floating on the Santiam River had to be rescued Sunday afternoon when they became stranded in rapids near Niagara Park.  It's a remote section of the river, and damage from last year's wildfires made it difficult to reach.  No one in the group was wearing life jackets.  Two rescuers became stranded when their raft overturned.  An Oregon Army National Guard helicopter was brought in to airlift everyone from the river.  One person was taken to a hospital with minor injuries.
