That sounds like good progress in understanding.  It might still be good
to ask of massgis when you hear back if that really does mean that if
the river moves the boundary moves.

The next question is who decides where the river is, and if the intent
is that they update the database.  And then if they haven't yet, where
the state government thinks the boundary is.

I suppose really we need a QA process to basically diff the state layer
against OSM and flag discrepancies for review.
