Typical Summer fly fishing on the Truckee River.
Cool mornings, hot and windy afternoons. Blue bird sun all day, (except the last few days of thunderstorms remnants from the monsoons in the 4 corners area).
Fishing is good if we get out in the mornings and nymph the pocket water. If you can wade around in the river, you're going to do much better than someone that can't. It's that simple.
Euro rigs usually reign supreme this time of year. Gets you in the water fish are holding in right now. Short precise drifts. Get yourself a 10,' 4wt, and learn to use it. That's the tool for the job.
So mostly nymphing -crayfish, all varieties, stones, smaller mayflies, and caddis.
Flows are pretty fair. Water temps do creep up in the afternoons. Boca on down to the stateline is good because of the cold outflow from the Little Truckee R. Everywhere else you need to have a thermomenter, use it, and take it upon yourself to practice ethical fishing. When it gets above 67, just stop. If you can't get out in the mornings to fish, especially through Reno, just don't fish.
