Who Owns Submerged Logs in a Riverbed? That Question Goes to a Jury

Who owns submerged logs in a riverbed?  A new opinion from Eleventh Circuit Court of Appeals says ask the jury.   

These submerged logs are also called deadheads.  When I was stationed in California on a Coast Guard patrol boat, we hit one near the Golden Gate bridge (mighta been a railroad tie).  Significant emotional event.
