If Votty/Bowydd is getting untopped then obviously that area's out of bounds during work, but does work mean any others near there, say.. Diffwys is affected by the location, i e. Maenofferen workers or security tell you to clear off if you go near Diffwys? I'm thinking Fridays + Saturday also.
Obviously the trouble is looking on maps and resources (e.g. Coflein) I'm not getting much feel for how it relates. I realise the solution is "get your wellies and coat and have a look" but it's not local to me so I wouldn't want to go there on say a Friday and have a wasted journey.
Any guidance or local knowledge appreciated
