Yes, this does help. The river network is very large and complex and adding
points at each confluence would take a very long time. After stepping back
and thinking how the outputs from the v.stream.* modules would be received
by the intended audience I realize that this detail is meaningless to
non-technical decision-makers.

Thanks very much,
