This is in the wrong place. This is not the Milwr Tunnel Outflow. So the marking of the tunnel all the way from the Herward Shaft in Dolphin to Bagillt is marked at the wrong trajectory. The Milwr tunnel exits at the Dee Bank, further NorthWest. If you look at a satellite photo of the Dee Bank, you can even see the sluice gate at the end of the tunnel, and the water outfall.
