Fifth Choke - A request

[marsrat]

Morning all. Hope you’ve had a brilliant sunny weekend.

Finally have the funding + manpower and means to dig Fifth Choke in Aggy.

Any armchair cavers / folk who’ve seen the end of it before and have any information/ideas of exactly which part to dig (or any thoughts at all about it)?

All information welcome and would be helpful

Cheers

Do we know where the water comes from ?

Was it Hereford C C who dug there originally ? Anything in their journals ?

From CSS Records Volume 19:

At the bottom of the Biza climbs, upstream goes to 5th Choke with its complex of digs on two main levels, the upper ones penetrate further.

5th Choke. This was the site a major dig by HCC and later some work by CSS. It is still intriguing.

Stream volumes on 26-6-1982:

Main Stream, upstream of 3rd Choke, 0.06 cu m per sec
Main Stream, upstream of 4th Choke, 0.07 cu m per sec
Lower Main Stream, upstream of lower waterfall 0.21 cu m per sec

ie 3 times as much water comes out of 5th Choke as goes into 4th Choke. Implies a major inlet (from Llangynidr?) between 4th and 5th Chokes.
