Had the most barbel caught in a day on the Kennet many years ago. I cannot remember where it was; my brother had just joined a club and found a fantastic swim; I went along as a guest. I remember we had to walk about a mile (or was it two) to get to this swim. Anyway my brother put me in this swim, as up till this time I had not caught many barbel' despite a few forays onto the Hamp Avon.
It was a perfect swim, a bend in the river with a weedy patch in the slack water which held the barbel and a fast line on the outside. Just swim feeder and maggots fished above the weedy patch.. Once they came on they just kept coming. I stopped counting after about 17, had over 20 barbel that day. No doubles, all around 6/7 lb. What a swim. I bet its changed now, that must have been 20 years ago.
A good read Steve, keep them coming.
