This was discussed on here recently when it was questioned why it was going to cost x thousands (or was it millions) of pounds to pile several hundred metres of a reservoir dam somewhere.

The first of the boats are out of the hole.

More work being done in this video including the spider digger at work.

This isn't meant to be a criticism of @Mac of Cygnet but the fact they said that "All the pics were taken by me and uploaded from my computer, not hosted by a third party." could suggest that their IT knowledge isn't great as obviously the pictures are hosted by a third party, in this case Imgur, and they seem to be confused as the pictures still exist on their computer which they would do as all you do is upload a copy. They may not know they are using a VPN as a lot of anti-virus and security software come with VPN functionality now. I've known people in the past that think that when you upload something you are moving it to an extension of your computer on the internet. Also it is worth remembering that the cloud is just someone else's computer and to treat it as such. The Photobucket fiasco and now the Imgur situation reinforces that.

I was going to say something very similar

So it's CRTs problem that some dog owners don't pick up after their dogs? Hate to break it to you but it happens everywhere. Just get a stick and flick it into the canal.

Probably because some department somewhere, probably with ecology in the name, has created a policy that for every x amount of new armco a percentage has to have a soft edge for nature, etc.

19 years must be a record!

Yes, the canal through there is on private land and the right of way does indeed stop at Coatesfield Bridge. It has been a few decades since I've walked that stretch so will have to go back and take a look.

😕

It is a picture used in several books. The one I referenced was published in 1988. Whether the quarry was called Coatesfield or Trewsbury probably depended on who you talked to. It is a quarry near Trewsbury House near Coatsfield Bridge. It is more than likely the large unmarked one level with Tarltonfield Barn on the map in my post above.

It means I can earn money and go boating when it suits me not when there's a gap between projects.

Yes I think so. I got the location details from the 1988 'Old Photographs' book which, in fairness, isn't always correct however I have found a link to the same picture which has it as Coatesfield https://narrowboatmagazine.com/converted/47056/last_traffics_on_the_ts_coatesfield__cirencester#:~:text=One of the last traffics,the quarry left by boat… It is one of the quarries marked on this map. Just after the canal takes a sharp right turn at Coatesfield Bridge, shortly after passing the roundhouse and railway bridge at Coates.

We had ropes cut when moored on the Avon at Pershore. Moored up facing downstream, went for a curry and several beers and came back to find the boats pointing upstream. There was a few minutes with us scratching our heads before someone on a neighbouring boat appeared to tell us what happened.

I agree. In my head I can imagine there's now a memo going around CRT departments warning about if they do have to share information with external organisations, maybe "select all" isn't the best way to do it 😄

It's already been mentioned on the thread linked by @David Mack above. It's on the Mon & Brec Canal.

Just slightly off topic, Stanegarth is now at the bottom of a lake in Leicestershire https://www.stoneycove.com/stanegarth/

That is the example I was thinking of above.

You need to think in three dimensions. If the landscape was completely flat and all the mine workings are below that level then yes, all the water would flow to the bottom and the concept wouldn't work. That isn't always the case though. If the mine was on a hill you could tap a water source for the wheel and also construct a horizontal tunnel for that water to exit the mine on the hillside above the majority of the mine workings. That wheel then drives a pump to lift water from deeper down. The water table doesn't sit at sea level. Even if your mine isn't at the lowest point in the landscape you will likely encounter water which needs removing. The fact that waterwheel driven pumps have existed in mines means that the concept works, even if just where the topography allows.

If it’s like the one I’ve seen in Cornwall they’re driven by water to drive a pump to pump water out. Sounds weird but the source water is diverted out at a higher level to what is being pumped out.

Just looking through Humphrey Household's book on the Thames & Severn Canal which references the wind pump and well I posted before. This [the well] had been sunk to a depth of 54 1/2 feet, whence a borehole had been driven some fifty feet deeper... ...the company had installed a "Wind Engine", or six-sailed windmill, to work a pump of eleven-inch bore. it was capable of throwing up "several tons of water every minute"

Just thinking, but you don’t need to pump up the whole height of the flight as current back pumps do. Most of the pumps historically probably just pumped from wells sunk into the aquifer which weren’t nearly as deep. The later well at Thames Head for the steam pump on a different site to the wind pump I posted earlier had side galleries which increased the amount of water available.
