hi steve,the stretch you are talking about is i think controlled by either barnsley or newark pisc.im not 100% sure on that though as i havnt bin up for about 3 months although was thinking about it at the weekend.If i remember rightly it £4 for a day ticket.usual trent species- bream roach chub and barbel.The bailiff told me that the best place for the barbel is on the river just behind the 2 lakes where the bend is,you also will prob have this part to yourself as you cant get your car down there(one of the reaons i love it)My mates have had quite a few barbel form this part but all i seem to get are the chub.Havnt had anything big but it is normally good fishing.
Hope that helps you mate.anything else just ask. best of luck
