Sorry I've taken over the post.
Where is James? I'd like a conformation also.
The water coarse went through a few changes over the years. Originally there was no waterfall and half of my garden area was another pond. I filled in the pond and routed the stream up higher in the orchard. I was able to run the route high enough to go over the rocks.
I actual did some of the digging in the rain. Water seeks its own level, so I could dig and watch the flow. Move a little up hill, a little down. Later on I borrowed my brothers transit.
I'll have to dig out some old photos and scan them into my computer.
