Utah fishing reports
238 reports for Utah — what's biting, water temps, and where to focus.
Cool-down turns on Green River browns, Flaming Gorge smallmouth
Fall's cool-down is reshuffling both ends of this fishery. Wired2Fish's account of a near-record 8.6-pound smallmouth caught this month describes the pattern reservoir anglers should watch for here: as water slides into the 40s and 50s, bass slide off shallow cover onto deeper structure and feed hard on baitfish. Below the dam, Field & Stream's fall live-bait roundup points anglers toward a bottom-bouncing minnow rig on a barrel swivel to keep bait in the strike zone for big browns — the same seasonal cue that typically starts pushing Green River's brown trout toward pre-spawn aggression.
Green River flows settle into steady fall pattern in the Uintas
Fall cooldown is settling into the Green River system this morning. USGS gauge 09261000 on the Green River reads 61°F with flow holding at 3,040 cfs, while the upper gauge (09234500) shows 58°F and 2,190 cfs. A third station in the Uinta high country (404417108524900) reports 59°F with no active flow reading. All three readings were logged between 4:15 and 4:45 a.m. local time, showing consistent, moderate fall flows across the basin.
Green River tailwater flows hold steady into fall cooldown
USGS gauge 09234500, right below Flaming Gorge Dam, is reading 58°F on 2,190 cfs today. A few miles downstream near Jensen, gauge 09261000 shows the river has warmed to 61°F on 3,040 cfs, while the reservoir-area gauge 404417108524900 holds at 59°F. That gradient — cold at the dam, warming as it runs downstream — is the classic tailwater signature, and it's holding steady heading into the equinox.
Uinta lakes and Green River waters shift into fall transition
Late September marks the turn into the fall transition across Utah's Green River and Uinta Lakes system, the stretch when summer holding patterns break down and fish begin shifting with cooling water and shortening days. The Uinta high-lake season is winding down as nights turn colder at elevation, while the Green River's tailwater stretches settle into their typical autumn rhythm. A First Quarter moon this week keeps solunar activity moderate, without the strong dawn and dusk pushes a full or new moon would bring.
Flaming Gorge tailwater eases into its early-fall rhythm
The Green River tailwater below Flaming Gorge Dam is settling into its early-fall pattern this week, as shorter days and cooling overnight air start to soften the summer pressure this stretch usually carries through August. Dam releases keep flows and water temperature far steadier here than on a freestone river, so the seasonal shift shows up gradually, in lighter daytime crowding and a longer comfortable fishing window, rather than as a sudden change in the water itself.
Green River trout settle into steady fall rhythm
The USGS gauge near Jensen (09234500) read 58°F with flow holding at 2,170 cfs as of early this morning, a comfortable, stable tailwater setup for trout as days shorten. No captain or shop reports came in from the Green River or Uinta Lakes corridor this cycle, so we're reading conditions off the gauge and seasonal norms rather than fresh bite reports — treat species calls below as typical-for-the-date rather than confirmed hot bites. Elsewhere in Utah, Outdoor Hub reported wildlife officials treated a stretch of Mill Creek in Salt Lake County with rotenone to remove illegally introduced brook trout and protect native cutthroat populations — a reminder that native cutthroat management is an active priority statewide, even though that work is unrelated to the Green River itself. Flows at this level typically mean good wading access and clear water below the dam. Check current Utah DWR regulations before keeping any fish, particularly cutthroat, given the ongoing native-species emphasis.
Green River tailwater trout dial in as fall hatches build
Green River flows near Jensen held steady at 2,170 cfs with water temperature reading 58°F just after 4:30 a.m. this morning, per USGS gauge 09234500 — solidly in the range where Flaming Gorge tailwater trout stay active through the fall shoulder season. Direct on-the-water reports from this stretch are thin this week, but the broader fly-fishing press points to patterns worth carrying: MidCurrent's latest tying roundup highlights flies built for the surface-to-open-water transition as fall hatches intensify, while Caddis Fly (OR) notes grasshopper patterns are still drawing trout willing to move several feet for a meal late in the season — both applicable to a tailwater fishery like this one. Utah wildlife managers, per Outdoor Hub, also treated a separate Salt Lake County stream (Mill Creek) with rotenone this month to protect native cutthroat trout, a reminder that the state is actively managing its wild trout genetics statewide. Expect steady, technical fishing rather than a blitz.
Fall Green River trout bite steadies as UT backs native cutthroat
The Green River is holding a steady 59°F at 2,320 cfs as of Saturday evening, per USGS gauge 09234500 — solid tailwater conditions for an early-fall feeding window. No angler reports specific to the Green River or Uinta Lakes surfaced in our sources this cycle, but Utah's native-trout story is active elsewhere in the state: Outdoor Hub reports the Division of Wildlife Resources treated roughly three miles of Salt Lake County's Mill Creek with rotenone to remove an illegally introduced brook trout population and protect native cutthroat, a sign of how seriously the state is managing its trout fisheries this season. On the Green itself, expect typical mid-September behavior — rainbows and browns feeding actively on midges and terrestrials as flows and temps ease toward fall norms, with Uinta high-lake cutthroat still catchable ahead of the first hard cold. Check current Utah DWR regulations before harvesting anything, especially in waters tied to native-species recovery work.
Green River tailwater settles into a stable fall trout pattern
The Green River below Flaming Gorge Dam is running a steady 2,320 cfs at 59°F as of Saturday evening, per the USGS gauge at Greendale (09234500) — both numbers sitting right in the seasonal window for a dam-controlled tailwater easing into fall. No fresh on-the-water reports came in from Flaming Gorge or Green River sources this cycle, so species status below leans on typical September behavior rather than a confirmed bite. Statewide, Outdoor Hub reported Utah wildlife officials treated Mill Creek in Salt Lake County with rotenone to remove an illegal brook trout population and protect native cutthroat — a different drainage from the Green, but a sign the state is actively managing cutthroat fisheries this month. Expect rainbows and browns to stay steady as flows hold consistent, with kokanee starting to stage for their fall run. Check current Utah DWR regulations before harvesting any species out of this tailwater section.
Green River tailwater stays steady as Uinta Lakes ease into fall
The gauge below the Uintas logged 58°F water and 1,870 cfs this morning (USGS 09234500) — cool, stable tailwater numbers that keep trout metabolism active without late-summer heat stress. We don't have direct shop or guide "what's biting" reports on this stretch this week, so treat the species notes below as seasonal expectations grounded in temperature and flow rather than confirmed bites. Elsewhere in Utah, Outdoor Hub reports state wildlife officials treated Mill Creek, a Salt Lake County stream outside this coverage area, with rotenone to remove illegally introduced brook trout and protect a native cutthroat population — a reminder that cutthroat conservation is an active statewide priority this fall, even where it doesn't touch the Green River or Uinta Lakes directly. With a new moon overnight and darker skies, dawn and dusk feeding windows should be the strongest bet through the weekend. Check current flow releases before planning a float, since tailwater levels can shift with dam operations.
Green River Tailwater Trout Settle Into a Cold, Steady Early-Fall Bite
A fresh USGS reading from gauge 09234500 below Flaming Gorge Dam puts the Green River at 58°F and 1,870 cfs this morning — cold, clean tailwater water that keeps trout metabolism dialed in even with flows running on the fuller side. We didn't turn up a direct captain, shop, or agency report out of the Flaming Gorge/Green River corridor this cycle, so this update leans on the gauge alongside what's moving in trout-fishing circles more broadly. MidCurrent's latest Tying Tuesday roundup spotlights the GFC Fly, a midge-style pattern built for 'the clear, pressured water of stillwaters and tailraces' — a near-exact match for this stretch's character. Caddis Fly (OR) is also flagging strong late-summer terrestrial activity, with trout moving several feet to eat a hopper off the surface, a pattern that should still be drawing looks into the afternoons. Separately, per Outdoor Hub, Utah wildlife managers recently treated a Salt Lake County stream to protect native cutthroat, a sign the state is actively managing its trout fisheries this season.
Green River trout perk up as Utah's high country cools toward fall
USGS gauge 09234500 read 57°F and 1,830 cfs before dawn today, comfortable trout water that should hold through the week as Utah's Green River tailwater and the high Uinta Lakes settle into the early-September cooldown. No direct on-water reports came through our Utah freshwater feeds this cycle, so we're leaning on the seasonal pattern: as surface temps ease off summer highs, browns and rainbows typically feed more actively through the middle of the day instead of pulling back to dawn-and-dusk windows only, and cutthroat in the higher Uinta lakes respond to the same cue. Wired 2 Fish's note this week on warm-season panfish sliding to suspended, deeper structure is a useful general reminder that fish follow temperature, not the calendar — worth keeping in mind on any Uinta lake that's still holding summer warmth in its top few feet. A waning crescent moon means darker nights, which can nudge feeding toward daylight hours.
