weather was perfect! sunny and warm, caught 5 fish using a mix of streamers and dry flies. biggest one was a 18 inch brown, clear water made it easy to spot them. saw some folks fishing but i had some nice quiet spots to myself. loved it!

what a day! moderate rain but i didn’t let that stop me. got a few bites on nymphs and caught 2 nice cutthroats, both around 12 inches. the river was a tad high but the fish were active! dried off with some hot coffee afterwards, can't beat it!

fishing from the bank today, had some rain off and on. lost a couple good ones but finally landed a healthy 15 inch rainbow on a stimulator. man, the colors were beautiful! packed up when it started pouring, but it was a fun adventure.

overcast skies today but wasn’t too bad. got my best catch which was a fat 16 inch brown on a #14 pheasant tail nymph! felt like a tug of war but totally worth it. river was flowing nicely, fished till sunset and lost track of time.
