Colorado fishing reports
147 reports for Colorado — what's biting, water temps, and where to focus.
Low water forces early starts on Colorado's trout rivers
USGS gauge 09095500 read 74°F on the evening of August 17, well above the 68°F line Cutthroat Anglers' 'Trout and Warming Rivers' report flags as the point to stop fishing and protect stressed fish. Flow held near 1,550 cfs, thin enough that Cutthroat Anglers' Matt Campanella describes trout as grouped up in deeper pools rather than spread through typical lies, with 2026 shaping up as what Pat Dorsey Fly Fishing calls one of the worst drought years on record for Colorado. Colorado Trout Hunters has echoed a historically bad snowpack season. The upside, per Campanella, is that concentrated fish are still willing to eat for anglers who hike a little further and fish early. West Slope tailwaters covered by Crystal Fly Shop show the same pattern of low, clear water pushing anglers toward downsized flies and early starts before afternoon heat sets in.
Drought Pushes Colorado Anglers to Dawn Patrol as Rivers Run Low
Rivers across Colorado's Western Slope are running low, clear and cold this week, with Crystal Fly Shop reporting voluntary CPW closures in effect on parts of the Roaring Fork, Crystal, and Colorado Rivers near Glenwood Springs. Cutthroat Anglers confirms it: this is shaping up as a record-low water year, and Pat Dorsey Fly Fishing calls 2026 among the worst droughts on record for the state. The upside, per Crystal Fly Shop, is that fish have pushed off the banks into deeper runs and are still eating, especially early and late before afternoon heat pushes water temps up. The Frying Pan tailwater below Ruedi Reservoir stays cold in the 40s year-round and is fishing PMDs, BWOs and midges. Cutthroat Anglers is urging anglers to stop fishing once water hits 68°F to protect stressed trout. Anglers Covey notes the slower, lazier late-summer pace typical of the dog days.
Tailwater Trout Still Biting as Drought Squeezes South Platte, Arkansas
Pat Dorsey Fly Fishing's latest Drought Update calls 2026 the worst water year on record for Colorado, and that's setting the tone for South Platte and Arkansas tailwater trips right now. With flows thin statewide, Cutthroat Anglers is reminding anglers to carry a thermometer and quit once water hits 68°F, treating heat stress as the real threat to fish this month, not a lack of bites. Anglers Covey, working out of Colorado Springs near the Arkansas River corridor, says the dog-days pattern has settled in: rivers slow down, fish get lazier, and the best windows are early morning and late evening before afternoon sun pushes temps up. On the technique side, AvidMax's fly-tying desk is still turning out midge emerger patterns built for tailwater trout keying on small bugs in skinny, clear water. None of this is shutting the bite off, it's just narrowing the clock anglers have to work with.
Low, Clear Water Pushes Colorado Trout Into Dawn and Dusk Windows
CPW voluntary closures are back in effect on the Roaring Fork (noon-to-midnight, Highway 133 bridge to the Colorado River confluence) and on the lower few miles of the Crystal River, per this week's Crystal Fly Shop report, as ongoing drought keeps flows low and afternoons warming fast. Crystal's upper stretches stay cold, clear, and are fishing well right now. Below Ruedi Reservoir on the Frying Pan, water holds in the 40s year-round and afternoon hatches of PMDs, BWOs, and Green Drakes keep fish looking up; Crystal Fly Shop recommends light 6X tippet worked early or late near the dam. Cutthroat Anglers is sounding the same alarm shop-wide: once water pushes past 68°F, it's time to stop fishing and let fish recover. Matt Campanella's low-water tips, via Cutthroat Anglers, note fish are grouped up and still willing for anglers ready to hike farther or downsize their presentation.
Low water pushes South Platte, Arkansas trout into early windows
Cutthroat Anglers is urging Colorado tailwater anglers to carry a thermometer and stop fishing once water hits 68°F, a direct response to what Pat Dorsey Fly Fishing calls one of the driest years on record for the state, with snowpack among the lowest ever measured. On the South Platte and Arkansas systems, that translates to low, clear flows and trout pulled into deeper, cooler pockets rather than spread across the usual runs and riffles. Cutthroat Anglers' low-water notes point anglers toward the fish that remain, which are grouped up and still willing to eat for those willing to hike a little farther or fish a little lighter. Midges remain the bread-and-butter pattern this time of year per AvidMax's ongoing tying series, and Colorado Trout Hunters' Dream Stream stretch of the South Platte sits quiet between its spring and fall runs of migratory browns. Early mornings and late evenings are the play right now.
Frying Pan Stays Hot as Drought Pushes Trout to Early, Late Windows
Frying Pan River tailwater flows are holding near 145 cfs below Ruedi Reservoir, with water staying in the 40s below the dam even as the rest of the region bakes — Crystal Fly Shop calls it some of the season's best fishing right now, with PMDs, BWOs and Green Drakes firing in the afternoons. Elsewhere the story is drought: the Roaring Fork and Crystal River are running low and clear, and Crystal Fly Shop reports CPW voluntary closures in effect on stressed stretches of both, plus a full-day closure on the Colorado River near Glenwood Springs. Cutthroat Anglers (CO) is telling anglers to stop fishing once water hits 68°F, and Pat Dorsey Fly Fishing (CO) calls 2026 possibly the worst drought on record here. As flows keep dropping, Crystal Fly Shop notes flies are sizing down and fish are pulling off the banks — expect a technical, small-fly bite through the heat.
Colorado trout rivers stay tight as summer heat and drought squeeze flows
Our Colorado River gauge logged 72°F this morning, already above the 68°F mark Cutthroat Anglers flags as the point to stop fishing and protect stressed trout. It's the latest sign of a summer that Pat Dorsey Fly Fishing calls the worst drought on record for the state, with historically low snowpack pushing flows down early. Crystal Fly Shop's reports on the Roaring Fork and the Colorado River between Glenwood Springs and Rifle note CPW voluntary closures are in effect on parts of both, while the Crystal River stays open below Redstone and is fishing great in low, clear, cold water above the closure line. The Frying Pan remains a reliable cold-water refuge, running in the 40s below Ruedi Reservoir with afternoon PMD, BWO, and Green Drake activity. Anglers Covey notes August heat has rivers slowing and fish turning lazier, while Cutthroat Anglers' Matt Campanella says fish are grouped up and still catchable for anglers willing to hike further or downsize.
Colorado tailwaters go dawn-patrol as historic drought grinds on
Colorado is in what Pat Dorsey Fly Fishing calls one of the worst drought years on record, and the strain is visible across the state's trout water. Crystal Fly Shop reports several Western Slope rivers running low, clear, and warm enough to trigger voluntary afternoon closures, with anglers downsizing flies as flows keep dropping. Cutthroat Anglers echoes the same caution statewide, urging anglers to quit for the day once water hits 68 degrees and to handle fish gently in the heat. South Platte and Arkansas tailwaters are dam-controlled and typically hold up better than freestone rivers in a drought year, but the same heat-stress rules apply here too. Colorado Trout Hunters, who guide the Dream Stream stretch of the South Platte, note it has a history of producing strong runs of migratory browns and rainbows, though summer fishing on that water still leans on early starts. Anglers Covey Blog sums up the mood well: dog-days pace, with rivers slowing and fish turning lazier through the heat of the day.
Low, Clear Rivers Push Colorado Trout Bite to Early Mornings
Colorado's rivers are running low and gin-clear as the 2026 drought grinds on, with Crystal Fly Shop reporting the Roaring Fork down to 113 cfs at Aspen and 410 cfs at Glenwood Springs, and the Crystal River sitting at just 107 cfs at Redstone. CPW voluntary closures are in effect on stretches of the Roaring Fork, Crystal, and Colorado rivers to protect stressed fish during the hottest part of the day, per Crystal Fly Shop. Cutthroat Anglers is urging anglers to carry a thermometer and quit fishing once water hits 68°F, while noting that despite historic low snowpack, the fish that remain are grouped up and still biting for anglers willing to hike further or fish lighter. On the Frying Pan below Ruedi Reservoir, dam-release water stays in the 40s, keeping afternoon PMD, BWO, and Green Drake hatches reliable even as everything else struggles.
Low Flows Push South Platte, Arkansas Trout Into Early Windows
Flow at USGS gauge 06701900 held near 215 cfs in the pre-dawn hours of Aug. 9, a modest read for South Platte and Arkansas tailwater country in what Pat Dorsey Fly Fishing calls one of Colorado's worst water years on record, in the company of the lean stretches of 1975-78, 2002, 2012, 2018 and 2020. Cutthroat Anglers is flagging the same statewide low-water squeeze and reminding anglers to check a thermometer before wading in: once water hits 68°F, it's time to stop fishing and let trout recover. Anglers Covey Blog, working out of Colorado Springs near the Arkansas drainage, describes classic dog-days behavior this time of year, slower rivers and lazier fish, with the shop crew leaning on early starts to beat the heat. Midges remain the bread-and-butter tailwater food source per AvidMax Blog's ongoing tying coverage, with foam-back and tube-style emergers built for the clear, pressured water these fisheries are known for.
CO trout retreat to cool water as drought tightens river closures
Colorado's rivers are running at historic lows this week, and Crystal Fly Shop reports voluntary CPW closures now covering the Roaring Fork from noon to midnight (Highway 133 bridge to the Colorado River confluence) and a full-day closure on the lower Crystal River, with the Colorado River itself closed all day between Glenwood Springs and Rifle. Outdoor Hub confirms the pattern is regional, noting heat-driven restrictions now span more than 1,800 miles of Western rivers this summer. Cutthroat Anglers is urging anglers to stop fishing once water hits 68°F to protect stressed trout. Pat Dorsey Fly Fishing calls 2026 possibly the worst Colorado drought on record. Still, fish haven't gone anywhere — Crystal Fly Shop says the upper Crystal and the tailwater below Ruedi Reservoir on the Frying Pan are fishing well, since dam-release water there stays in the 40s regardless of the heat topside.
South Platte and Arkansas Trout Turn Cautious as Dog-Days Heat Holds
No fresh buoy or gauge telemetry came through for the South Platte and Arkansas corridors this cycle, so this update leans on regional angler intel. The dominant theme across Colorado shops right now is heat management: Cutthroat Anglers is telling clients to carry a thermometer and quit fishing once water hits 68°F, a real concern after what Pat Dorsey Fly Fishing calls one of the driest years on record for the state. Anglers Covey notes the classic August slowdown is setting in, with rivers and fish both moving at a more leisurely pace during peak afternoon heat. Tailwater sections below South Platte and Arkansas dams typically hold cooler, more stable flows than freestone water even in a drought year, which should keep fish feeding on a tighter window. AvidMax's midge patterns remain the technical go-to for tailwater feeding lanes right now.
