I have been fishing a small stocked stream for years and have been relatively successful. I fish a pool area about 20 feet wide, 60 feet long and at most 4 feet deep and cast my fly downstream. This season the fish seem to be very selective and I have been having difficulty even getting hits though I have hooked and landed several Brooks and Browns. The fish seem to be larger and fatter this year which I attribute to the large swarms of insects that seem to be present continuously. I have tried matching the insects with different sizes of flies and have put the flies within inches of fish but to no avail. Fish would rise and take insects only inches from my fly. I am not spooking the fish since there are rises all around, some as close as 10 feet from me. Is the presence of so many real insects causing my problem? Is there a different technique that may be more productive? Any suggestions would be greatly appreciated.
Thanks,
Tony
