I know this thread is old now but just found it. There are plenty of carp in the Wensum but the best place in my experience is either New Mills Yard if u have a boat, or anywhere near Wensum park. Ask around the park for the stretch called the swans nest, you shouldnt go far wrong there but as said be carefull at night and dont go alone coz theres been 1 or 2 phone muggings around that area. Ive fished it many of times and had some nice fish in there. Some good bream and tench there aswell if anyones interested
