The CDG newsletter is the definitive reference for dives in the UK and also accepts relevant reports concerning dives in other countries. It is also a useful repository for those researching sites, compiling sump indexes and rescue teams that may need to come looking for you. You do not have to be a member of the Group to contribute. Non-members are welcome to report their dives to make the information available to a wide audience, avoid duplication of effort and ensure proper credit. To submit a report click here.
