There are loads mate. Old Stan Lewis moaned at me for fishing it at Bewdley. Told me it would ruin it for local anglers as it would stop the roach feeding later on in the season. I only went in for fresh supplies! Had good days at Bridgnorth, Hampton loade, Arley and Bewdley on it. Find the Ron Lees roach video and he does that...hemp on the severnI’m probably wrong but I don’t think there are enough roach on the middle Severn to make it that worthwhile hemp on the hook. On maggot you get dace, chub and chublets, and perch. Would love to fish your area of the Thames as hemp fishing is something I don’t have a clue about.
