The Redmires Reservoirs are a group of three reservoirs in Fulwood, Sheffield, South Yorkshire, England. They are fed from the Hallam Moors by various small streams including Fairthorn Clough. The three reservoirs are named Upper, Middle and Lower and date from 1836 and were built to provide clean drinking water via a water course down to Barker's Pool 5½ miles away following the devastating Sheffield cholera epidemic of 1832.

(History via

While the iron bridge was built in 1854 by Wilson and Robinson Eagle Foundry Park, Sheffield, the plughole is believed to have been a later addition to the dam in the late 1950s / Early 1960s.


The visit

So, I had been thinking about doing this for a while but somehow never got round to it. I had intended on walking in from the other end of the outfall tunnel but when I arrived to take a photo from above and there was nobody around I decided I may as well climb down the proper way.... Helped by a conveniently placed piece of wood from an old doorframe I dropped down to the bottom of the plughole.



From the plughole, the outfall tunnel runs east into an open culvert after around 150m. The tunnel itself is pretty clean, except for a bit of rubbish and, of course, the spiders.




The exit itself features some nice stonework and warrants a couple of pics and closer attention.



It doesn’t end there either as an open culvert then runs through the field...


... then closes again to travel under the road in a similar pipe to the one before.​


Here it joins an other spillway culvert in line with the middle dam bank. This is where I made my way out and back along the road to my starting point...



... brushing the spiders out of my hair...​
