Boshboil Arm, BCN

Boshboil Arm
21 October 2010

I'm not sure if this section is really lost or not. A short sunken section certainly qualifies.

Entrance to Boshboil Arm

It forms part of the Bumblehole loop which was short cutted by an embanked section built as part if the Netherton Tunnel project. The loop remained in water till the far end subsided into pit workings thereby leaving two distinct arms.

OS Map 1901
The northern arm is the shorter of the two, maybe 200 metres long and sometimes navigable. At the time of or visit the channel was clear and a boat could penetrate to the end providing the skipper didn't mind reversing out. At other times it is clogged with weed.

 In water - and dry
Beyond this navigable length the line becomes indistinct within a stand of trees, probably occupying a depression now half filled by garden walls. Just as you think you must be on the right line the shape of narrowboats loom above you  and you have stumbled across the far end of Bumblehole.
