Found this one by chance after looking further upstream at a dam overflow tunnel...
Blackburn Brook flows under Thorncliffe industrial estate on the edge of Chapeltown near sheffield for approximately 500 metres.
We got in at a mid point between a 6ft RBP that goes for 200m under a factory site and a fairly big concrete box that goes for maybe 60m under the main road.
Entrance to the first bit was deep and smelly, every step released bubbles of shit gas and 'ladies products' were floating to the surface, still we carried on...
The outfall.
The water was proper murky but we did see a couple of rainbow trout that followed us on our journey upstream, thankfully it did get a bit shallower...
Deep Water.
...and a bit shallower further up.
Thankfully towards the infall the water shallowed right down to a trickle in the bottom of the tube..
Infall...
Next there was a small tunnel under the railway line with hardly any water in it.
We explored further up and found yet another 6ft RBP section but the water absolutely stank and we found dead fish in the pooled water so we decided that not having a gas detector we'd leave this bit well alone... So we wadered back the way we came, met our trouty friends again and headed for the concrete box to finish off the explore.
I was expecting this to be boring and for the most part it was..
But towards the end we found some buried bridges that looked ancient! Must be 150-200 years old easily looking at the stonework.
Thanks for looking!
