Updated Documents

New Northern Sump Index

After years of work the Northern Section have released their new sump index. CDG Chairman Scoff says "Each time a new Sump Index is produced, thanks to countless hours of research and writing, we may be excused for thinking that the golden era of exploration has been and gone. Instead this record of the current 'state of play' will, I am sure, act as a catalyst for the next phase of explorations" The new Index will be available to order soon from the CDG on-line shop.

Weil's Disease

JNC has written an important article on this dangerous condition that cave divers are prone to be exposed to. Very important information that everyone should read.

Pozo Azul DVD

A DVD of Jason Mallinson and his team's epic exploration of the Pozo Azul system in Spain is now available from the CDG shop. I'll be getting my copy and posting a review as soon as possible, but order quickly as stocks are limited.

Look out for the new book about Wookey Hole, covering 75 years of diving exploration from 1935 to the present day. It is available from the CDG shop and more information is available from the book's website (see the CDG shop for details).

Wookey Exposed- A film by Gavin Newman

Wookey Exposed- A film by Gavin Newman
Gavin's movie of the exploration of Wookey Hole has been widely praised for the graphic portrayal of the famous cave.
The movie is even more remarkable as it gave such an insight into the conditions at the 'end' of the sump that the focus of exploration changed and spctacular progress was made.
The movie has a web site at and is available by mail order in case Santa did not put a copy in your stocking this year...

Details of a new dark (but clear air surface) diving environment can be found on their new website. Not affiliated with the CDG, an interesting new facility if you've had your fill of flooded quarries!

12th October 2004 - Membership card updated

A slight change has been made to the wording of the membership card to clarify the status of a qualified diver. The new cards will begin to be issued from November. If you need a card please send DOB, DOQ, section, and passport style photograph (if electronically limit to 60KB) to your section secretary. Old syle cards remain valid (see image further down this page). The other side of the card remains unchanged.

Cave Diving - The Movie!

A forthcoming movie promises to cast cave diving in the starring role as the hero battles fearsome monsters in the sumps of Rumania! More at CDG News hopes to bring you a review of this exciting release when it comes out in 2005.

Insurance for CDG members

CDG insurance is operational once again and all paid up diving members are covered for the year 2004 - 2005.

As you may or may not know,as of the 7.11.03. the BCRA insurance scheme became void.

This means that any site with which there is an access arrangement/agreement must be regarded as closed in the regard of cave diving activities. Wisely, I believe that the Somerset Section secretary, to keep good faith with the Wookey & Cheddar Managements, has already implemented a voluntary ban.

It also means that equipment loaned to members from their sections would not be covered in the case of an accident as the group does not have indemnity, if claimed against.

5th May 2003 A65 Closures Planned

It seems that there are major roadworks planned for the A65 in Gargrave, north of Skipton, this Summer. These may cause disruption for divers heading for the Dales by this route. There will be periods of single lane traffic, and also complete closures with a lengthy diversion for some periods. More details can be found at

24th April 2003 Lot & Dordogne guide second edition

A new edition of Andrew Ward's popular Underwater Guide to the Lot & Dordogne has now been published. Featuring information on 21 major sites in the region the format is of a drawn survey of each site and text description. The descriptions principally cover the distance a committed tourist diver might achieve, with references to further research material for the explorer.

The guide is laser printed on 60 pages and includes a small selection of colour photographs of both below and above ground. Appendices give a useful English - French glossary, and information on local dive shops (few) and recompression facilities (fewer). There are also short notes of lesser sumps and a hanful of dry caves of interest.

No cave diving holiday to the area should set off without a copy. The guide can be obtained from:

1st February 2002 Llygad Llwchwr sump passed at last

Martyn Farr and a team of diggers have opened the final sump in Llygad Llwchwr, passing it after 10m to discover 200m of dry passage. Apparently there are plenty of leads which they are actively attacking.

Llygad Llwchwr is an important resurgence cave in the Western Brecon Beacons, the terminal sump has resisted all efforts for many years. Hopes are high for a major system that is known to take water from sinks as much as 7km away. Martyn has kindly provided some photographs of the team and new discovery:
