Thanks Tijmin & Andrew - name deleted! :-) Thought it should have something
to explain the open space between 2 houses:
but having now read the "No name" policy can see that's wrong. Have also
changed the node & pipeline details.

That's it - there's a surface drain & manholes on the street, with the
visible pipe going into the lake, so I marked the pipeline in back to the
street. As above, I've ow changed the tagging so that the pipeline is
marked through the easement, with an outlet at the lake edge.

That's the way I've always done it as well! To my mind, a stream running
through a culvert is still a natural waterway that we've put a lid over -
if it was a man-made dug out channel, that would make it a drain.
This tagging also appears valid for a big stormwater drain where you can

I'd *strongly* recommend that you don't try walking into tunnels that are
flooded! - you're going to get very wet & the consequences could be bad :-)

Welcome to the Club - at least it's not just me! :-)
