Hi, I have seen a dead carp at the side of coombs near the boat house a few months back, it was probably around the 6-7lb mark when it was living. They definately exist and im sure in all sizes, they must breed, I have also seen them rolling on the surface whilst I have been lure fishing for Pike through the reed beds. People are always there fishing and Ive heard a tale of a 38lb fish being caught recently, dont know if its true. Have a walk round and chat to a few people see what they say. Probably the sheer size of the place is against you as said by others. I would like to hear if you have any further advice or information. Anyone know of any other waters near by? Whats Bowden Hall Lake like?
