(Portland, OR)  --  A man is recovering after becoming stranded in the Willamette River.  KATU reports a man was walking near the river early yesterday morning when he heard someone yelling for help.  He looked into the water and saw a man hanging onto the bow line of a 200-foot yacht.  The man reportedly waved his arms at people on the boat to alert them to the man in the water, and the boaters responded by throwing him a life jacket.  Portland Fire and Rescue then pulled the man from the water and took him to a hospital with non-life-threatening injuries.  It's not yet clear how the man ended up in the water.
