Colorado fishing reports
217 reports for Colorado — what's biting, water temps, and where to focus.
Low, clear Colorado trout water favors stealth and small flies
Flows on the Colorado River system are modest this week. USGS gauge 09095500 reads 1,520 cfs with water at 51°F, and gauge 09106485 shows 653 cfs at 53°F. Those temperatures sit comfortably inside a good trout range, well below the 67 to 68°F level where Pat Dorsey Fly Fishing and Cutthroat Anglers (CO) advise anglers to stop fishing. Crystal Fly Shop (CO) describes nearby Roaring Fork, Frying Pan and Crystal waters as low, clear and cool, with lighter tippets and smaller flies producing best. Rainbow Trout have taken tiny, shiny patterns like Sparklewing RS2s and Flashback PTs, and the same shop reports Tricos and a mix of PMDs, BWOs and midges on the Frying Pan, where 6x and 7x fluorocarbon is recommended.
Low, clear Colorado rivers set up a finesse fall bite
Both main-stem gauges are running cool and steady this morning. USGS gauge 09095500 reads 1,560 cfs at 52°F, and gauge 09106485 reads 659 cfs at 51°F. Those temps sit comfortably under the 67 to 68°F cutoff that Pat Dorsey Fly Fishing and Cutthroat Anglers (CO) give for when trout fishing should stop, so heat stress is not a concern right now. Crystal Fly Shop (CO) describes nearby Roaring Fork and Frying Pan water as low, clear and cold, with lighter tippets and smaller flies doing the work. They suggest 6x and 7x fluorocarbon where fish are selective, and Duranglers-style stealth applies on skinny water. Tiny, shiny patterns such as Flashback PTs and RS2s were picking up fish there. Treat that as a regional pattern, not a report from these exact stretches.
Tailwater trout get picky as fall settles in along the Front Range
Low, clear tailwater is the story for South Platte and Arkansas anglers this week. The USGS gauge 06701900 is reporting modest flow, and per Colorado Trout Hunters the 2026 drought has left tailwaters, the rivers below dams, as the most reliable option on the Front Range. Pat Dorsey Fly Fishing echoes that, pointing anglers toward tailraces and urging them to watch temperatures closely. Fall posts from Flylords Mag say autumn is streamer season, with trout hunting baitfish and sculpins as insects thin out.
Low, clear water favors finesse for Colorado fall fishing
The Colorado River near Parachute-area gauges is running steady this week. USGS gauge 09095500 reads 1,600 cfs with water at 55°F, and gauge 09106485 shows 739 cfs at 57°F. Both temperatures sit in a comfortable range for fish that have been stressed by a hot, dry summer. Colorado shops describe the same backdrop. Pat Dorsey Fly Fishing calls this drought the worst on record and says tailwaters remain the best option. Crystal Fly Shop reports low, clear, cool rivers where lighter tippets and smaller flies are the most productive, with tiny and shiny patterns like Sparklewing RS2s and Flashback PTs picking up fish.
Low clear flows set up a fall fishing window on the Colorado River
Gauge 09095500 reads 1,680 cfs at 51°F and gauge 09106485 reads 706 cfs at 51°F, both cool and fishable for early morning starts. Crystal Fly Shop (CO) describes nearby Western Slope rivers as low, clear and cool, with lighter tippets and smaller flies doing the work. Pat Dorsey Fly Fishing (CO) still advises watching water temperatures closely during the ongoing drought, but readings this week sit well under the 67 to 68°F stress threshold cited by local sources.
Western Slope rivers fish low and clear as fall settles in
The Colorado River gauge at 09095500 reads 1,660 cfs and 55°F, while gauge 09106485 shows 1,160 cfs and 58°F. Those temperatures sit comfortably below the 67 to 68°F cutoff that Pat Dorsey Fly Fishing and Cutthroat Anglers (CO) tell anglers to respect, so mid-October water is not the stress point it was in summer. A smaller site, gauge 391953108130201, is running just 14.4 cfs and should be treated as a trickle. Crystal Fly Shop (CO) describes the upper valley rivers as low, clear and cold, with tiny and shiny flies like Flashback PTs and Sparkle RS2s picking up fish. Stealth matters more than pattern, and they recommend 6X and 7X fluorocarbon tippet in the clear water.
Low, clear Colorado rivers reward stealth and small flies this fall
Fall water is low and clear across the Colorado and Arkansas drainages. USGS gauge 09095500 reads 1,620 cfs and 52°F, while gauge 09106485 shows 1,530 cfs and 55°F, both comfortable for trout. Crystal Fly Shop describes nearby Roaring Fork and Frying Pan water as low, clear and cool, with tiny, shiny nymphs like Rainbow Warriors, Sparklewing RS2s and Flashback PTs picking up fish. Frying Pan anglers are seeing overlapping BWO, PMD and midge hatches, so Crystal Fly Shop suggests 6x and 7x fluorocarbon tippets and a careful approach.
Low, clear Colorado rivers set up a fall tailwater window
Gauge 09106485 reads 1,610 cfs with water at 54°F, and gauge 09095500 reads 2,190 cfs at 53°F, so the main stems are running cool and fishable this morning. Gauge 391953108130201 shows a small tributary at 103 cfs. Crystal Fly Shop (CO) describes the Roaring Fork as low, clear and cool, where lighter tippets and smaller flies are producing, with tiny and shiny patterns like Rainbow Warriors and Flashback PTs picking up fish. Per Crystal Fly Shop (CO), the Frying Pan is low and cold with picky fish keyed on overlapping hatches, and they suggest 6x and 7x fluorocarbon.
Low, clear water favors light tackle and tailwater trout
Flows are lean across the Colorado and Arkansas basins this week, with one gauge reading 698 cfs and 58°F and another 2,130 cfs and 56°F. A third gauge near 76 cfs shows how thin the smaller drainages are running. Crystal Fly Shop describes the Roaring Fork as low, clear and cool, with lighter tippets and smaller flies most productive. Tiny and shiny patterns like Rainbow Warriors, Sparklewing RS2s and Flashback PTs are picking up fish there. Crystal Fly Shop also reports Frying Pan fish keyed on overlapping hatches, so stealth and 6x to 7x fluorocarbon matter. Pat Dorsey Fly Fishing says tailwaters remain the best option in this drought year and suggests quitting once water reaches the upper 60s.
Colorado tailwaters offer the steadiest fall trout window
Gauge readings near Grand Junction show the Colorado River system running at a workable, cool-water stage. Two gauges report 57°F water, with flows of 808 cfs at gauge 09106485 and 1,510 cfs at gauge 09095500. A smaller site, gauge 391953108130201, is running just 13.9 cfs. Per Cutthroat Anglers (CO), the guidance this drought year is to stop fishing once water reaches 68°F, and these readings sit well under that line. Pat Dorsey Fly Fishing (CO) says tailwaters remain the best option in the drought and advises quitting when temperatures hit about 67°F. Crystal Fly Shop (CO) reports low, clear, cold water on the Frying Pan with picky Brown Trout and overlapping hatches. They suggest 6x and 7x fluorocarbon tippet and careful stealth.
Low, clear Colorado tailwaters set the tone for fall trout
Gauge 09095500 on the Colorado River reads 1,570 cfs at 57°F, and gauge 09106485 reads 982 cfs at 58°F, so the main stems are carrying decent volume with water in the upper 50s. Small tributary gauge 391953108130201 shows just 11.8 cfs, a reminder of how thin the side water is. Crystal Fly Shop reports its valley rivers low, clear and cool, with lighter tippets and smaller flies most productive. Tiny and shiny is their motto, with Rainbow Warriors, Sparklewing RS2s and Flashback PTs picking up fish. On the Frying Pan, the shop notes superb dry fly fishing on overlapping hatches, and picky fish that reward 6x and 7x fluorocarbon.
Tailwater trout tighten up as fall settles over the Front Range
Fall is settling in on the South Platte and Arkansas tailwaters, and the pattern that matters this week is clear, cold, low water with picky, pressured trout. Colorado Trout Hunters describe a drought year in which tailwaters, the rivers below dams, have been the most dependable fisheries on the Front Range. Pat Dorsey Fly Fishing says the same, calling tailwaters the best option in a record-dry season and urging anglers to watch water temperatures closely. The USGS gauge 06701900 is reporting a modest, steady flow, which fits that low-water picture.
