Planning Consent was granted a long time back ( "You can do what you want as long as it doesn't spoil the garden" , plus, she loves running water so that's a winner
Since Rik has so beautifully described his stream construction and we've all admired the results, I see no need to reinvent the wheel and I shall broadly follow his method, adapting things as required ( thanks once again Rik).
There really is only one location where the stream is feasible and that means cutting a gap in the concrete slab trackbed and then threading between track and an apple tree and then between track and a Camellia bush. When I poured the track bed originally I did this section in two goes with quite a long time gap between and the join subsequently cracked, so the plan is to make use of that by widening the crack sufficiently for the stream and a bridge.
This picture shows the planned route at the start. This shows the future location of the lower end, the sump will be just in front of the roof tile ( I have a number of theses dotted around the garden to give me somewhere to stand and get at the track if necessary). The leafy green lump at the LH side is a Lonicera Nitida tunnel.
As I said, I made a start yesterday by excavating a small trench from the lower side of the bridge to the sump position and a sump hole. These are just to check the viability before I irrevocably attack the existing trackbed and will need enlarging in due course to make room for the bank rocks, etc. So far all seems OK.
I think the next step is to cut the concrete Watch this space but don't hold your breathe!
