Green River tailwater cools into a fall brown trout window
Water on the Green River tailwater is running cool and steady this week. USGS gauge 09261000 shows 2,460 cfs at 56°F, while gauge 09234500 reads 2,300 cfs at 50°F, and gauge 404417108524900 reports 54°F. That spread puts the water in the comfortable range for trout. Fall is the season Trout Unlimited and Caddis Fly (OR) both point to for small, subsurface patterns, with Caddis Fly (OR) calling the Perdigon a hot fly this fall. Reno Fly Shop (NV) reports trout focusing on small bugs such as Blue Winged Olives and midges as temperatures cool, which is a useful template for tailwater fishing in general.
Green River trout settle into a steady fall pattern
The Green River below the dam is running 2,610 cfs at 56°F per USGS gauge 09261000, while the upstream gauge 09234500 shows 1,880 cfs and 51°F. A third gauge, 404417108524900, reads 53°F. That 5-degree spread between gauges is the story this week: cooler water upstream and slightly warmer water downstream. Brown Trout and Brook Trout should be comfortable across all three readings, and the temperatures sit in a range that keeps trout feeding through the day.
Fall tailwater trout key on small bugs and heavy nymphs
Gauge 09234500 reads 1,880 cfs at 51°F this morning, while gauge 09261000 shows 2,610 cfs at 56°F. Cool, steady water like this is what pushes trout into their fall feeding pattern. Per Caddis Fly (OR), the Perdigon is a hot fly this fall, a slim, heavy pattern built to get down fast. Reno Fly Shop (NV) reported late-September trout focused on small bugs, including Blue Winged Olives and midges, and suggested Baetis nymphs and Zebra midge patterns. Both reports are from other waters, but the bug-and-nymph approach carries over to cold tailwaters at this time of year.
Green River tailwater trout fishing holds steady into mid-October
The Green River system is running cool and clear-flowing, with USGS gauge 09261000 reading 2,570 cfs at 57°F and gauge 09234500 at 2,330 cfs and 50°F. A third gauge, 404417108524900, shows 54°F. That spread of temperatures sits comfortably in the range where Brown Trout and Brook Trout stay willing to feed through the day. Per MidCurrent's Tying Tuesday, small midge-style patterns excel in clear, pressured water on stillwaters and tailraces, and that fits what these readings suggest for the Green this week.
Green River tailwater trout settle into a fall rhythm
The Green River tailwater is running cold and steady heading into mid-October. USGS gauge 09261000 reads 2,570 cfs and 57°F, while gauge 09234500 shows 2,330 cfs and 50°F. A third gauge, 404417108524900, reads 54°F. That spread of temperatures puts trout in comfortable territory, and the steady flow keeps feeding lanes predictable. Per Caddis Fly (OR), terrestrials like ants are still on the menu this fall, and Perdigon-style nymphs are a hot pattern. Reno Fly Shop (NV) noted small bugs, midges and Blue Winged Olives drawing trout on another western river as the season turns. Both are general fall patterns for western trout, so expect them to translate here.
Green River trout settle into steady fall pattern
Water on the Green River drainage is cool and fishable this week. USGS gauge 09261000 reads 2,540 cfs at 56°F, while USGS gauge 09234500 shows 1,900 cfs at 50°F, and USGS gauge 404417108524900 reads 55°F. That spread matters: the colder 50°F water is where Rainbow Trout and Brown Trout should feel most comfortable and feed through the middle of the day, while the warmer reaches fish best earlier. Per MidCurrent's recent Tying Tuesday, a beaded purple nymph is built for low-light, overcast days, and a spare midge-style pattern is described as excelling in clear, pressured water of stillwaters and tailraces.
Green River tailwater trout settle into a steady fall pattern
The Green River below the dam is running clear and cool, with USGS gauge 09261000 reading 2,540 cfs and 56°F on the morning of October 11. A second gauge, 09234500, shows 1,900 cfs and 50°F, so the water cools noticeably as you move away from the release. That spread matters for Rainbow Trout and Brown Trout, which tend to hold where temperatures sit in the low-to-mid 50s and feed steadily. Per Reno Fly Shop (NV), trout on a western tailwater-style river this fall are keyed on small bugs: Blue Winged Olives, midges and a few remaining caddis. Their suggested patterns, including the RFS Perdigon, Zebra Midge and Pullover BWO, translate well to this kind of water. A reading of 55°F at gauge 404417108524900 backs up the picture of stable, comfortable trout temperatures.
Green River trout stay tuned to cool, steady tailwater flows
The Green River system is running cold and clear-minded this week. USGS gauge 09261000 shows 2,690 cfs with water at 56°F, while gauge 09234500 reads 2,180 cfs at 51°F and gauge 404417108524900 reports 54°F. That spread is a useful map: the upstream reading at 51°F sits squarely in the comfort zone for Rainbow Trout, Brown Trout and Brook Trout, while the 56°F reading is warmer but still workable for a trout bite when fish feed actively. Tying content from MidCurrent this week points to low-light, overcast patterns and spare midge styles for clear, pressured stillwaters and tailraces, which is the right frame for this water.
Green River tailwater trout settle into a fall rhythm
Cool, steady water is setting the tone on the Green River tailwater this week. USGS gauge 09261000 reads 56°F with 2,690 cfs, while gauge 09234500 shows 51°F at 2,180 cfs, and a third gauge near the Colorado line reads 54°F. That spread of low-to-mid 50s water sits in a comfortable range for Rainbow Trout and Brown Trout, which should feed willingly through the day rather than only at dawn and dusk. For what's working elsewhere in the fall trout world, Reno Fly Shop (NV) notes that cooler temperatures have trout focused on small bugs, including Blue Winged Olives, midges and a few remaining caddis. Caddis Fly (OR) calls the Perdigon a hot fly this fall, and MidCurrent highlights midge-style patterns for clear, pressured tailrace water.
Cooling flows set up a fall shift on the Green River
Green River flows are showing real spread this week. USGS gauge 09234500 reads 51°F on 2,180 cfs, a notably cooler reach than gauge 09261000's 60°F on 2,540 cfs just downstream. A Uinta Lakes site (USGS 404417108524900) holds a steady 55°F with no flow reading, consistent with still water this time of year. That nine-degree swing across one drainage is the story: the cooler stretch is holding its fall pattern while the warmer reach has yet to fully turn over, and the lake sits right in between.
Dam release keeps Green River tailwater running cold and steady
Flows on the Green River tailwater below Flaming Gorge Dam held steady at 2,180 cfs with water at 51°F as of October 9 (USGS gauge 09234500) — the classic cold bottom-release signature this stretch is known for, even as the calendar moves into mid-October. Downstream at the Jensen gauge the river had warmed to 60°F on a comparable 2,540 cfs (USGS gauge 09261000), and reservoir water near the dam sat at 55°F (USGS gauge 404417108524900).
Green River's cold tailwater holds steady into mid-October
The Green River's cold-water signature is holding strong below Flaming Gorge Dam, where USGS gauge 09234500 near Greendale reads 50°F with flow at 2,820 cfs. Moving downstream, USGS gauge 404417108524900 shows water warming to 58°F, and by the time the river reaches Jensen, USGS gauge 09261000 reports 60°F with flow eased to 2,290 cfs. That steady warming gradient from dam to desert reach is the signature of a healthy fall tailwater release, and it's sitting about where this stretch typically runs heading into mid-October.
