The problem is you can't do anything like that with rubber. It needs to
have a vertical end rather than horizontal.

Well loop the waterfall liner back up around something so it forms an
edge for the water that flows around the end and back along the
horizontal underside can drip from.

That's definitely worth looking into, but will mean getting a whole new
liner for the stream as it's too short to do that at the moment.

I was hoping not to have to rebuild the stream, but it could be a very
good solution.
