This evening I had company once more...
Warren tells me he knew a chap who took his dog fishing as it taught the dog to be patient. It is not working very well in our case.
Charles Cotton's Black Fly.
Charles Cotton really did create a versatile fly when he made his Black Fly. The Hawthorn Flies have nearly finished hereabouts but their memory lingers on. As a result the trout still eat biggish black flies with such ferocity they hardly need striking to set the hook. Basically they hook themselves. Terrestrial flies in general can be subjected to this ferocious style of attack from the trout. My pet theory is that the potential meal is a substantial one that has been known to escape suddenly, so the trout don't mess around with them. Bam!
The water was very bright facing into the west this evening and it was best to continue with the Black Fly even though the fish were clearly eating olives. "How can this be?" you may well ask, "Surely 'Matching the Hatch' is the best ploy?"
Have you tried this trick of using a dark fly on a bright water when the sun is low and leaving the 'Match the Hatch' policy behind for that evening?
Of course it is not always a good idea. If the fish are preoccupied on a particular natural fly then it is certainly best to maintain the normal rule of 'Matching the Hatch' as best you can.
