Ron and Ed,
"Times they are a changing" or words to that effect.
I live in the South East where lots of "Trout" reservoirs have switched over to coarse fishing, co's that's where the money is. No re-stocking and plenty of anglers ready to dosh out a fiver or more for a day ticket. Off the top of my head, here are some of them:-
Ardley, Ardingleigh, Darwell, Powdermill and Bough Beach, all formerly Fly Only trout reservoirs..
Ed, the idea about chucking bait into the water supply doesn't fit, co's all the reservoirs above are part of the water supply system. When you see the huge quantities of Canadian Geese and suchlike, doing their business in the water, and on the bank, a few maggots or a bit of groundbait cannot possibly do any harm.
