(Portland, OR)  --  Willamette Week reports there's so much trash in the water of the Willamette River that the State Department of Environmental Quality is proposing it be regulated under the federal Clean Water Act.  The river would be the third body of water in the nation to be regulated that way.  Only California's Los Angeles River and the Potomac in Maryland are as dirty.  The listing would give the DEQ a tool to pressure riverfront property owners to prevent camping or clean it up.  The DEQ invites public comment until June 17th.
