A stream has to be deemed navigable by a court of law otherwise its non-navigable by law.
If the navigability of a stream has not been determined by a court, then its navigability status is UNKNOWN.
When it's disputed in court, and the court rules, then the stream's status changes from unknown to either navigable or non-navigable.
This was what happened in the case of the Little Juniata River.
