Hi Bob,
There is a northern region which also encompasses the East Midlands, the RO is a chap called Richie Clarke. Rich can be contacted as below but membership is applied for online via the website. The year runs June 1st - May 31st but if you join now you’ll get the two magazines and all of the get togethers are from April - June in the main,the only thing you will have missed is the AGM which was at the beginning of November. There’s a Spring General Meeting in March. Rich is running a fish-in in the spring in Lincolnshire but I believe the water is more about quantity of fish rather than size. There’s at least one northern member who has caught a Yorkshire double but I don’t know the water. There is a members only forum and also a closed members only Facebook area. The forum is a bit quiet at this time of the year but obviously comes to life as the spring approaches.
Coming south will obviously increase your chances of a double but the south midlands has Sywell Reservoir which Tenchfishers can fish at no cost (just need to buy a council parking permit which is about £37 I believe). Sywell has produced some cracking Tench in recent years on organised fish-ins.
Thanks for the interest, I look forward to seeing your name pop up on the new members list
Regards
Bill
