Did you know its been raining?​

I know its not long past but does anyone know the effects of Mondays flooding has had on the dales caves?
With the amount of water around i am sure something will have happened?
Collapsed digs?
New passages opened?
New blockages?
Dangerous debris?

Just asking out of curiosity and for people to share their knowledge.

Its about to chuck it down again, likely be a few new tree trunks in Goyden. If I am feeling better I can let you guys know what it has done to one of the goyden digs tomorrow.

I'll be watching this with interest as I didn't go down to the Dales this w/e on the strength of the forecasts.

The levels today are not going to be as high as on Monday. I watch the floods because we have a dig that uses water. The Monday flood did a lot of work in our dig.

This is the Rawthey near Sedberg and is two images stuck together.

Should the title read "Monday 9th November"?

Yes it was pretty wet two days ago but nowhere near as bad a flood as it can be.
(Remember that one a few months ago which had a river coming out of the entrance to White Scar Cave?)

It had gone down massively yesterday but rivers are fairly high again today. My gauge has collected well over 100 mm over the last 6 days.

The main point is that the fells are soaked, so even a moderate rain event at the moment can bring the water up scarily fast - take care folks.

This post above is saying it's been edited by Captain Chris - have I said something I shouldn't? (Or does it automatically say that because you've taken the trouble to tweak the topic heading?)

Anyway, just tipped another 23 mm out of the gauge this morning, to add to the figure mentioned above.

Ah - thanks for explaining.  (y)

Just for interest, my gauge here in the Dales has now clocked 5 inches of rain over the last week. Saturday's looking a bit ugly as well . . .

I've been watching the rainfall and the river levels in order to plan caving trips. The week before last the water levels in rivers and in caves were unusually low for the time of year. It took a lot of rain before the river levels responded as quickly as you might expect at this time of year. The fells were very dry because of below average rainfall in September and October (about half the UK average). It wasn't until last week that the fells appeared to reach saturation and the river levels rose to the flood levels you would expect for the amount of rain.

The bucket outside my house filled up in about a week, does that help :) Maybe I should drop a ruler in there and I too can have a rain gauge :).

Anyway going down a mine this weekend so it can chuck it down as much as it likes!

Quite sensible but there are lots of caves to go to when it's very wet. Bar Pot into the main chamber is good. I've long had the ambition to see the main chamber fill up.

Take care.

Me too, but I recently had some good fun using the Small Mammal / Stile Pot alternative.

I'm not talking about just something to do on a rainy day; I'm talking serious underground storm chasing.

In a big flood the Main Chamber is truly awesome. On one occasion we found newly formed deep pools in South Passage. When the Main Chamber fills up water flows through South Passage and we missed seeing it by hours. I have heard a story of someone getting to the end of South Passage to find a lake but I don't know where that story comes from. It is also known to get higher than that.

Sunday will be the best day. The really heavy rain is forecast for Saturday night.

I once went down Bar Pot after a big thunderstorm the day before (or maybe two days before), and crawling along towards Main Chamber from the foot of the big pitch I became vaguely aware that there was something odd going on ? there was no draught. Anyway, shortly after we turned down S. Passage at the T-Junction we came across a sump. I walked in until the water was chest deep on me, but could see no sign whatever of an airspace.

It happened in 1982, a day or two after some poor soul died in Sunset Hole as a result of the thunderstorm.
