Dream stream, advice needed
Small spring stream in south eastern region, crystal clear most of the time. Width about 12' to 4', cascading pools, woodland. Very little if any fishing pressure.
There are very large wild browns and the size of the fish are truely unbelievable. I have been an avid, borderline obsessive fly fisherman for 40 years now specifically for wild trout, and have never seen anything quite like this stream. I caught several 16" to 18" and some smaller in large holes and started to see the big fish in deeper pockets and even in little 3' riffles. Needless to say, I have put quite an effort into connecting with the big guys. I have had several hook ups but the line was broken, and quite possibly cut off. I have fished the stream two to three times a week with one particular hole with 4 or 5 dream browns holding there.
I have had the medium trout smash elk hair caddis earlier in the season, as well as sown success with haresear #16's. Since the. The stream has rejected my best offerings. I have tried everything: caddis larvae, emergers, dries. Royal wulff with a prince dropper, groffitjs gnat, foam hoppers with droppers including prince nymphs, haresears, micro mayflies, woolies, stimulators, zebra midge, small foam beetles, lots of small nymphs.
I changed my fly line to a natural color and switched to a 13' leader 6x with dark color and 2lb tippet. I tried bead heads and non bead heads.
Needless to say, I am looking for sound advice and suggestions. Thanks for your time and any advice would be appreciated!
