Report: While it has not been as bad as it has been in other areas here in Northern California, smoke from the fires is definitely impacting the Fall River Valley. The fishing has remained very good. Morning offerings should be centered around the Trico spinner fall, the fish will congregate in seams and small eddies where the spent mayflies will collect. Look for fish gulping rhythmically on the rafts. You can also nymph the spinners, either a dry fished wet, or better yet the Drowned Trico under a small dropper. Big Callibetis are coming off later in the morning, The Last Chance Cripple in Callibaetis has been a good fly, also fishing a #14 Flashback Pheasant Tail has worked very well under an indicator or Big Head Moth. 

Hot Flies:  TB Drowned Rusty Spinner, PMD's, Norman's Wiggletails, Pheasant Tails, Mercer's Missing Link, Zug Bugs, and Leeches.
