Cycles: as one species begins to wane (barbel, perhaps, now, in the Kennet's case), another makes a return and has its moment in the sun. High time, as I can remember some lovely roach fishing on the river in the late 1960s to early 1980s. Just got to keep the river flowing, clean and "unsplurged" by all the canal boat traffic. As for the Avon Project, it has had my tacit support for several years (a little money of mine found its way into its coffers via someone else a few years ago), for I can remember Avon roach fishing of a quality so fine that I used to curse the sometimes 1- to 2-pounders spoiling one-hour-long, dace livebait-catching sessions, especially if I hadn't had the time to buy maggots and had to use a few slices of Wonderloaf.
Good luck, chaps.
PS - How good? I once watched Jack Harrigan fill three huge keepnets with quality roach, dace and chub in just a few hours on the Avon below Salisbury. He twice handed me the keys to his MK 10 Jag and asked me to bring him another big can of maggots and a bag of groundbait. THAT good.
