Truckee River flows are near perfect in early July 2025 at 250 to 600 CFS with great color. Water temps are climbing into the high 60s, so fish mornings and evenings and carry a thermometer. Hopper-dropper rigs are the main producer as grasshoppers show up. Size 16 caddis and size 16 PMDs are the top flies. Euro nymphing is kicking out fish in the bubbles.
What is the Truckee River fishing like right now?
Good, with the big caveat of rising water temps. Matt Heron reports flows are near perfect at 250 to 600 CFS with great color. Mornings have fished best and evenings have been good. It is mid-July, so the biggest factor is heat and protecting the fish.
What flies are working on the Truckee River in July?
Size 16 caddis and size 16 PMDs are the top producers, plus crayfish patterns and Pat's Rubber Legs. Hopper-dropper rigs are the main way anglers are getting fish now that grasshoppers have shown up. These are fly patterns rather than products we carry, so match them locally.
How should I rig for the Truckee River now?
Fish a hopper-dropper with a deep dropper, around 30 inches or less to your nymph, using a size 16 caddis or PMD. Euro nymphing is also kicking out plenty of fish as the trout transition into the faster bubble lines with the warmer water. Focus your effort mornings and evenings.
What are the water temperatures on the Truckee River?
Temps are hitting the high 60s, so hoot owl closures near 68 degrees are a real concern. Take temperatures throughout the day, in quicker water at least two feet down, and give the fish a break once it warms. Colder tributaries and the main river fish best early.
What is the outlook for the Truckee River?
Fishing stays good into September, but heat is the story until nights start cooling. The hopper-dropper game should hold. Nocturnal stoneflies may start popping in the next few weeks into August. Watch temps and fish mornings. Longer-term outlook was not specified in this report.
