Question of hydrology

There's a strong outflow of water in very wet weather from the west (natural) wall of the path up to Peak Cavern, just at the S-bend through the last cottages - I always assumed it was related to the culvert discovered when Dave Penney and gang were excavating Peakshole Sough, but it's not really close enough thinking about it. Can't think of any outflows in the centre of the village other than Odin Sough, which is kind of on the outskirts. Having looked at many maps recently, I also think that the outflows of Kronstadt Sough and Nunlowend Sough (after leaving the Hope Cement works area), merge near the fishing ponds, and then run NE to join Bradwell Brook after passing under Brough House.

but what about the other outflow in the center of Castleton ?

You seem to know more than you're letting on... :p

What knowledge have you got by infiltrating the locals?

Where abouts exactly is this other outflow? There is a mill stream that runs next to the main car park in the village - which I think just feeds its water from Peakshole water - but is there another? It would be slightly surprising as most of Castleton village itself is built on shale, not limestone.

That's the one and no it's not connected to peakshole asfaik. Today peak cavern was flooded and the main river was in spate but the mill channel as you name it only increased its flow by by a factor of 2. So where does the water come from ?

I believe the millstream water comes from the river. If you go along the riverside walk, you come to a kink in the path the feed to the millstream is just there under the path.

According to the above link the mill stream follows the medieval defences south-north before curving round to the east near the main car park.

It would put the water entry to this point somewhere south of the millstream. MATs probably right, but i could sent some young drunk people to crawl through the stream in the middle of the night if that would amuse you. :)

The Mill Leat comes off Peakshole Water at the weir on the river walk between Three Roofs and Goosehill Bridge. The level of the Leat changes but not dramatically as its flow is regulated by the weir. I used to live in Mill Leat Cottage opposite the Three Roofs Cafe, the Mill Stream flowed through our back yard. It always turned muddy in flood but never rose much. In summer there is always a big trout lurking in the entrance to the culvert where the Leat comes off.

This may be a daft question, but does the amount of water coming out of the resurgences/caves in Castleton more or less equal what is going in up at the P's plus percolation etc.

I've always thought that what comes out of Peak is far less than that seen in the main streamway.........

It could just be my perception.... :blink:

There are several places where you could potentially "lose" the water from the main streamway to the resurgence just on the left in front of Peak Cavern. though I doubt the flow is much different.

From surprise view ladders the first place where you could lose it is in Tom Browns inlet sump, in high flow down the streamway I don't know how much it backs up. hypothetically if the passage on the other side of this sump is right then water backing up on our side (the streamway) could force water to flow the other way through this sump. although given the flow measured only 3 months ago out of Tom Browns, It is improbable that the passage on the other side allows for a "perched" sump.

The second place is Styx inlet sump, again an inlet... so the same hypothesis about potential reversed flow can be applied here, and I think the flow is much weaker here, but blocked by an underwater silt bank.

Styx inlet is a righthand branch in the Halfway house/swinehole part of the Peak Cavern Trip (just on the left as you've come down the slide near the start).

Halfway House- Swinehole is the left hand branch, the water rejoins the cavern in the vestibule, but this section of dive is (as far as I know) blocked with debris, and is potentially the reason why the water backs up and floods the cave in the Three arches section and backs up the devils staircase. Who knows if there's an exit for the water in this section.
The water exiting the swinehole into the resurgence is clearly limited by the blockage and so the water resurging here doesn't change very much, and seen as the backing up is only caused by excess water from Speedwell exiting via treasury, there is not much difference between the Main Streamway and the resurgence.

If you mentally added up the flow of Squaws junction and the junction with Lake Passage (ink sump water) then you will probably get as much water as is exiting the resurgence.
Far sump barely has any flow at all.

The circular depression opposite Treak Cliff may be the WWII land mine crater mentioned in Ford & Rieuwerts Lead Mining in Derbyshire p 73.

I always understood the MamTor swallet, BJM & TCC water ran through the boulder bed at the front of Treak Cliff itself and got to Russett Well/Slop Moll without entering the Peak/Speedwell system.

Equally I thought the Dirtlow Rake drainage was the input to Ink Sump. Therefore where does the water in Far Sump come from?

The main input for Far Sump comes from the Titan stream and Far Sump Inlet Sump, as far as I remember. A dye-trace in the mid-80s of the lone shaft in the triangular field on Hurdlow to the west of Titan proved positive in the inlet sump, but I don't have the details to hand - I'm sure Pitlamp does. That shaft is a non-goer, sadly, being backfilled to surface, but a small climbing shaft adjacent does permit a few metres of access before hitting the backfill of the main shaft through a narrow slit.

Quick question about Peak aerology -

In very cold conditions a blowhole beneath the wall above Goosehill Hall emits enough (relatively) warm air to melt frost and snow the whole height of the wall and to form a condensation plume. The location, as far as I can remember, is at or near 53.340577, -1.780923 (copy/paste coords into Bing Maps search bar). Anybody ever had a look at it?

That's really interesting and an excellent article. Thanks for that pwhole, had wondered about it for years.

In the entrance to Peak cavern during the bad weather last week a stream flowed from a hole in the wall to the right of the concrete steps. The hole is about  3mtrs above the floor and approx 30cm in diameter. Any ideas?
