Utah fly fishing is built around the Green River below Flaming Gorge Dam, a cold tailwater that fishes every month of the year, plus the Provo, Weber and Logan rivers within a few hours of Salt Lake City. Fish the tailwaters any time, the freestones after runoff, and learn Utah's stream access law before you wade.

Utah is home water for me, so this page is personal. The state gives you a world-class tailwater, a technical river twenty minutes from a ski town, cutthroat canyons and high lakes you can have to yourself in August. It also gives you one of the most confusing access laws in the West.

This page is the Utah map: where to fish, when to go, the access rules and what our Utah guests have shared on the Fly Fishing Insider Podcast. For the longer take, read The Top 10 Fly Fishing Rivers and Lakes in Utah.

In January 2024 I drove to Dutch John through snow and wind strong enough to nearly blow me over when I stepped out of the truck, with John Isola and his brother Nick, to float the A Section of the Green River. We fished heavy sink tips and streamers because the day was short and cold, and John stuck a good brown on a chartreuse and white streamer inside the first ten minutes. By the take-out we had seven browns, bighorn sheep, moose, mule deer and bald eagles, and the ramp had been deserted all day. The next morning brought six inches of fresh snow and storm warnings, and we called it. That is winter on the Green: empty, beautiful and at the weather's mercy. The full story is in our Green River winter trip report.

Where to Fly Fish in Utah

• Green River below Flaming Gorge Dam: a Utah Blue Ribbon fishery with water running roughly 40 to 60 degrees all year. The A Section runs 7.2 miles from the dam to Little Hole, with a trail along the bank for wading. The B Section runs from Little Hole to Indian Crossing in Browns Park, and the C Section continues to the Colorado line. Fish numbers are highest in A and fish size grows as you go downriver; B and C are reached only by boat or gravel road. Expect midges, blue-winged olives, yellow sallies and cicadas.
• Provo River: the Middle Provo is a tailwater below Jordanelle Reservoir between Park City and Heber, and the Lower Provo runs below Deer Creek Reservoir through Provo Canyon. Park City guide Zach Lassek told the Fly Fishing Insider Podcast in July 2023 that the Middle Provo is all wade fishing with no drift boats, that summer parking lots can be full by 8 a.m., and that a bounce rig is the local standard for nymphing. Read our Provo River guide.
• Weber River: another Blue Ribbon fishery, holding brown trout, cutthroat and whitefish. The upper Weber from Holiday Park to Echo Reservoir has its own access rules after a 2017 Utah Supreme Court decision, so read the DWR's Weber guidance before you step in. More in Weber River: Utah's Hidden Gem.
• Logan River: a canyon river along US-89 in northern Utah. Browns dominate the lower canyon and cutthroat take over upstream, and the DWR says the river has one of the highest cutthroat trout densities it has documented. See our Logan River guide.
• Stillwater: Strawberry Reservoir (rainbow, cutthroat and kokanee) and Flaming Gorge Reservoir (lake trout, rainbows, kokanee and smallmouth) are both Blue Ribbon fisheries, and the Boulder Mountain lakes are the summer escape. Start with The Strawberry Pinnacles and Boulder Mountain Lakes.

The Green River starts in Wyoming and flows into Utah through Flaming Gorge, so if you are fishing the whole system, our Wyoming page covers the Green below Fontenelle Dam upstream.

Utah Stream Access: What Visitors Get Wrong

Utah water belongs to the public, but the bed under it often does not. Herbert "Bert" Ley of the Utah Stream Access Coalition walked through the history on the Fly Fishing Insider Podcast in July 2021. A 2008 Utah Supreme Court ruling recognized the public's right to wade privately owned streambeds as long as they did no harm. In 2010 the legislature passed the Public Waters Access Act, which took that right away without written landowner permission, and the Coalition was founded in response. In 2023 the Utah Supreme Court upheld that law.

Bert's example is the one every visitor should hear: you cross a ladder stile at a legal access point on the Weber, wade downstream, cross a property line you never saw, and get cited for trespass. The Utah Division of Wildlife Resources says you may not walk on the private bed of a public waterway without permission, but you may float over it and fish from the boat if you launched at a lawful access point. Check the DWR stream access page before every new river.

When to Go Fly Fishing in Utah

For a first Utah trip, plan on July through October for the freestones and any month at all for the Green River below Flaming Gorge Dam. Runoff pushes the freestones high in late spring while the tailwaters hold up. The DWR does not publish a statewide hatch chart, so treat the table below as general guidance from our own Utah days.

Snowpack and reservoir releases change the picture every year, so check flows before you drive.

Utah Tips from Podcast Guests

• Rig before dark and fish a riffle-fed pool for the dusk caddis push
  Many of the biggest fish in a pool only come out as the light fades. Tie on before sunset, sit below a caddis riffle, and carry a headlamp with a red-light mode.
  Herbert "Bert" Ley, Utah Stream Access Coalition, on Stream Access: What Happens Behind Closed Doors
• Carry Sharpies to recolor one simplified fly pattern in the field
  A parachute Adams in several sizes plus a black and a brown marker covers more hatches than a box full of exact matches.
  Zach Lassek, Park City, Utah guide, on How it Feels to Be a New Guide on High Pressured Water
• Dip a weighted leech at undercuts, or fish after dark, for big trout
  The largest trout in a river feed at night and hide under cover by day, so drop a heavy leech at every undercut instead of blind-casting open water.
