The Truckee River is fluctuating a bit from the storms earlier in the week, but is stabilizing around 375 cfs. Fall is definitely upon us. Storms are beginning to stack up and colder temperatures are moving in. On colder days fish have been becoming active later in the afternoon. Fly selection is getting simpler as most insects are tucking into rocks and preparing to hibernate. Smaller mayflies and caddisflies are the main food items for the trout. I’ve been fishing 16s and smaller. I’ll occasionally still put on a stone fly if I need need to get deep, but focusing on baetis and caddis patterns will produce more in the long run.
Water temps have dropped sub 50 degrees in the mornings. This has deterred some fish from eating in the mornings, but has not seemed to affect where they are in the river. Moderate to moderate-fast water is still holding fish. Focusing on structure and pockets has been key. Afternoon hatches have been prevalent in the afternoons right as the sun begins to get low in the sky. A mixture of pale evening duns and blue winged olives in size 20-16 have been the primary hatch with some caddis out east of Reno.
