The Upper O is fishing fair to good…. Flows are moderate at 65cfs and hatches of small caddis continue to come off in the AM and PM..Nymphing and stripping streamers will get you the most action on this water if there is NO surface activity.. Tiger midges, small PT’s, Hares ears and WD-40 type stuff are all still getting action.. Some small red Copper Johns as the top fly on the nymph string recently took some fish for me as well… Small Elk Hair Caddis and Griffith Gnat style patterns will see fish mouths when they are looking up.. For streamers one can tie on your pattern of choice and have some pretty good luck most times of the day.. Dont spook the fish with the streamers though, cast past them and have the proper set-up to get the pattern down to the fish..
