Top 5 Utah Rivers Fishing This Week | September 2026

The Middle Provo River was flowing on the report date at 234 cfs (normal) with a falling trend. Flows were rated fishable on the report date. Water Temperature: 54°F (prime). The Verdict: Excellent Conditions This week’s forecast shows temperatures ranging from 64-82°F. Calm winds support dry fly presentations.

Insect Activity: The Provo’s Hydropsyche caddis are still firing every evening, so a size 16-18 X-Caddis or Elk Hair Caddis swung through the softer edges around dusk will draw eats. Water is running a prime 54°F, which keeps a solid Trico spinner fall going first thing in the morning — carry size 22-24 spinners and be ready for gently sipping risers on the flats. Once the sun climbs, scuds and sow bugs (size 16-18) become the bread-and-butter subsurface pattern.

Where to Fish: Work the tailouts and glassy flats below Deer Creek Dam at first light for the Trico spinner fall, then shift to the riffles and seam lines as the morning warms for caddis emergers. Get on the water early — the forecast shows a 40% chance of afternoon thunderstorms building by early afternoon.

Gear Tip: Start with a two-fly nymph rig and a yarn indicator early. Shift to dry fly or dry-dropper during hatch windows. A 9-foot 5X leader with light tippet keeps the rig natural in these flows.

Presentation: Start shallow, then add weight or depth as you move into deeper runs and pockets. Use longer drifts to cover tailouts and seam water.

The Currant Creek Below Reservoir was flowing on the report date at 35 cfs (normal) with a stable trend. Flows were rated fishable on the report date. The Verdict: Excellent Conditions This week’s forecast shows temperatures ranging from 52-70°F. Calm winds make indicator nymphing more effective.

Insect Activity: This small below-dam tailwater is running lean at 35 cfs, so it fishes technical and clear — scuds, sow bugs, and worm patterns (size 12-16) stay productive all day, and they get especially good right after a dam release stirs up the bottom. Midges are the only steady hatch on the water this week, with size 20-22 Rojo Midges and Zebra Midges working the deeper slots.

Where to Fish: At this flow, target the deeper plunge pools and slower runs directly below the dam where fish stack up and hold — the skinnier riffles upstream are gin-clear and spook easily. Drop down to 5X or 6X tippet and approach from downstream; a worm pattern trailed behind a small scud is a good two-fly rig right after any release.

Gear Tip: Start with a streamer rig in softer edges. Switch to a two-fly nymph rig and a yarn indicator as flows settle. A 9-foot 5X leader with light tippet keeps the rig natural in these flows.

Presentation: Start shallow, then add weight or depth as you move into deeper runs and pockets. Use longer drifts to cover tailouts and seam water.

The Middle Weber River was flowing on the report date at 172 cfs (normal) with a rising trend. Flows were rated fishable on the report date. The Verdict: Excellent Conditions This week’s forecast shows temperatures ranging from 61-79°F. Calm winds make indicator nymphing more effective.

Insect Activity: The Weber’s brown trout run big here — averaging 16-18 inches — and September puts them in an aggressive pre-spawn mood, making this a strong window for streamer fishing. Pheasant Tail Nymphs and Parachute BWOs (size 18-20) cover the subsurface and the season’s first cooler-morning Blue-Winged Olive activity, while scuds and sow bugs stay a reliable year-round staple in this stretch.

Where to Fish: Focus on the deeper runs, undercut banks, and current seams between the Echo Reservoir and Wanship bridges — this is structure-oriented water built for a Woolly Bugger or Clouser Minnow stripped along the bank. Flows are a stable 172 cfs, so it’s a good week to swing streamers through the deeper bends in the morning before working nymphs through the tailouts once the sun is higher.

Gear Tip: Start with a streamer rig in softer edges. Switch to a two-fly nymph rig and a yarn indicator as flows settle. A 9-foot 5X leader with light tippet keeps the rig natural in these flows.

Presentation: Start shallow, then add weight or depth as you move into deeper runs and pockets. Use longer drifts to cover tailouts and seam water.

The Duchesne River – Middle Tabiona was flowing on the report date at 97 cfs (normal) with a stable trend. Flows were rated fishable on the report date. The Verdict: Excellent Conditions This week’s forecast shows temperatures ranging from 59-77°F. Calm winds make indicator nymphing more effective.

Insect Activity: No single hatch is dominating this Uinta Mountains freestone right now, which makes it prime late-summer terrestrial water — grasshoppers and ants are on the menu, so a size 10-12 Thunder Thighs Hopper or Chubby Chernobyl fished tight to the bank will draw attention. Caddis and attractor patterns (size 16 Elk Hair Caddis, size 12 Royal PMX) round out a solid searching-pattern lineup for the pocket water.

Where to Fish: At 97 cfs and holding low, work the pocket water and riffle-run seams where oxygenated current concentrates fish, and don’t skip the grassy cutbanks — that’s where the hoppers are landing. A hopper-dropper rig (Thunder Thighs Hopper over a Zebra Midge or Caddis Larva) covers both the terrestrial bite and the subsurface players in one pass.

Gear Tip: Start with a streamer rig in softer edges. Switch to a two-fly nymph rig and a yarn indicator as flows settle. A 9-foot 5X leader with light tippet keeps the rig natural in these flows.

Presentation: Start shallow, then add weight or depth as you move into deeper runs and pockets. Use longer drifts to cover tailouts and seam water.

The Price River – Lower Fish Creek was flowing on the report date at 68 cfs (normal) with a stable trend. Flows were rated fishable on the report date. The Verdict: Excellent Conditions This week’s forecast shows temperatures ranging from 53-71°F. Calm winds make indicator nymphing more effective.

Insect Activity: Fish Creek below Scofield Reservoir is running a modest 68 cfs, and like most below-dam stretches, scuds, sow bugs, and worm patterns get most productive right after a release. Terrestrials are also in full swing this time of year — size 12 Chubby Chernobyls and Hippie Stompers are worth a look along the banks in the afternoon, backed up by size 16 attractors like the Soft Hackle Hare’s Ear.

Where to Fish: Fish the riffle-to-run transitions closest to the dam outflow first, especially if you can time a visit to a release — that’s when the worm and scud bite turns on. As the day warms, move to the grassy banks downstream and work a hopper or ant pattern tight to the edges; a stealthy, methodical approach helps keep the fly in the feeding lane.

Gear Tip: Start with a streamer rig in softer edges. Switch to a two-fly nymph rig and a yarn indicator as flows settle. A 9-foot 5X leader with light tippet keeps the rig natural in these flows.

Presentation: Start shallow, then add weight or depth as you move into deeper runs and pockets. Use longer drifts to cover tailouts and seam water.
