IANAH, but I would say splitting the existing ways is correct, but they
should retain all their existing tagging. It seems that "reach" describes a
part of a "river" - they are not mutually exclusive, so waterway=reach
would be the wrong approach. I would just add name:reach=blah to the
specific named reaches. It's probably also useful to group the segments
into a relation.
