I have been fishing the mouth of the river deveron now for a few months I'm new too fly fishing and have had some ok sized brownies on the don but nothing over 8 inches on the deveron apart from 1 lost seatrout. It's really slow moving water apart from one small riffle which is on the tail of a pool but because it is slow moving and I don't see many rises from decent fish what would be my best method or choice of flies? Any help would b much appreciated as a lot of ppl say there are no big fish there and it's a wast of time but I want too prove them wrong lol
