Record drought pushes CO trout into cool tailwater refuges
Water temps below Ruedi Reservoir on the Frying Pan are holding in the 40s even in mid-July, per Crystal Fly Shop, making it one of the few reliable cool-water refuges as Colorado's rivers run historically low. Pat Dorsey Fly Fishing is calling 2026 the worst drought on record in the state, and Cutthroat Anglers is urging anglers to carry a thermometer and stop fishing once water hits 68°F to protect stressed trout. CPW has responded with voluntary closures: an afternoon shutdown on the Roaring Fork above Carbondale, a full-day closure on the lower Crystal River, and a full-day closure on the Colorado River between Glenwood Springs and Rifle. Crystal Fly Shop reports the upper Crystal River, still open, is fishing "some of the best of the summer," with low, clear, cold water pushing fish off exposed banks. Flies are downsizing across the valley as flows keep dropping and fish group up in the remaining cold-water pockets.
Trico hatches carry South Platte trout through a historic drought
Morning trico spinner falls are keeping South Platte tailwater trout dialed in even as Pat Dorsey Fly Fishing (CO) calls 2026 one of Colorado's worst recorded droughts, with snowpack among the lowest on record statewide. Gink and Gasoline's account of the South Platte trico hatch still applies this time of year — thick mats of tiny mayfly spinners collect in the surface film during the morning window, giving technical anglers a reliable bite before the heat builds. Cutthroat Anglers (CO) reports Colorado's rivers are running historically low and warm, and recommends anglers stop fishing once water hits 68°F to protect stressed trout, a real risk on Front Range tailwaters right now. The shop's low-water pro tips note fish remain active and grouped up for anglers willing to hike farther or downsize tippet. On the South Platte's Dream Stream reach, Colorado Trout Hunters continues building a reputation for migratory lake-run browns, though that run is more a spring/fall story than a midsummer one.
Midges and tricos carry South Platte tailwaters through drought lows
Pat Dorsey Fly Fishing's midsummer Drought Update frames 2026 as one of the worst water years on record for Colorado, and that reality is shaping how South Platte and Arkansas tailwater anglers need to fish right now. With snowpack and runoff historically low, Cutthroat Anglers is urging statewide caution: once water hits 68°F, it's time to stop fishing and protect stressed fish. On the technique side, low, clear flows favor small and precise presentations, per AvidMax Blog's midge patterns like the Titan Tube Midge ('deadly in clear water and cold conditions') and the tailwater-tuned Chocolate Foam Back emerger. Morning trico spinner falls, the kind Gink and Gasoline describes happening on the South Platte, remain a reliable summer window for picky tailwater trout. Earlier this season, Colorado Trout Hunters reported one of the better migratory-fish runs in years on the South Platte's Dream Stream, a solid signal heading into the back half of summer.
Colorado freestones turn on as this drought year's runoff fades early
The Colorado River near Glenwood Springs is on the back end of runoff and fishing 'sensational' with 'happy fish,' per Crystal Fly Shop, which also has the Roaring Fork producing on large attractor patterns and Rubberleg Stone nymphs at higher flows out of Aspen and Basalt. The Crystal River is dropping fast toward what the shop calls its best stretch of the year, and the Frying Pan tailwater below Ruedi Reservoir stays low, clear, and reliable with daily BWO hatches and fresh PMDs showing up. All of this lands in what Pat Dorsey Fly Fishing is calling the worst drought on record for the state, a read echoed by Cutthroat Anglers, which points to historic-low Western snowpack pushing runoff out weeks early. The upside anglers are reporting: low water has concentrated fish rather than shutting them down, and those willing to hike farther or downsize tippet are finding grouped-up, actively feeding trout across the freestones and tailwaters alike.
South Platte trico falls turn on tailwater trout despite drought lows
Morning trico spinner falls are back on the South Platte's tailwater stretches, the same hatch Gink and Gasoline once described watching so densely that a single scoop of the hand came up with dozens of bugs. That pattern is holding again this July, and it's arriving during one of the driest years on record. Pat Dorsey Fly Fishing's Drought Update ranks 2026 alongside 2002, 2012, 2018, and 2020 as a historically lean water year for Colorado, and Cutthroat Anglers' low-water tips echo the same story across the state's tailwaters: flows are thin, but the fish that remain are grouped up, active, and catchable for anglers willing to hike a little farther or downsize their tippet. AvidMax's clear-water midge patterns are built for exactly these conditions. Expect technical, low-and-clear fishing on the South Platte and Arkansas tailwaters this week, with the best window right at first light.
Colorado trout dial in as summer flows drop and warm
Afternoon USGS readings on the monitored gauge (09095500) show water pushing to 79°F with flows holding near 1,780 cfs, a classic mid-July low-water pattern across Colorado's trout water. Crystal Fly Shop reports the Colorado River near Glenwood Springs is on the back end of runoff, with green drakes, golden stones, PMDs and caddis all showing, and nymphing rubberleg stones and drake imitations producing well. Cutthroat Anglers is framing the historic low snowpack as opportunity rather than crisis, noting fish are active and grouped up for anglers willing to hike farther and downsize tippet. Pat Dorsey Fly Fishing flags 2026 as among the driest years on record for the state. AvidMax's current tying lineup, including a jigged CDC PT Tungsten and a Callibaetis nymph, matches the technical, low-clear-water game trout are keying on right now. Expect a slower midday and a stronger dawn-and-dusk bite as afternoon temps climb.
Trico spinners and terrestrials take over CO's tailwaters
Flow at USGS gauge 06701900 held near 249 cfs early this morning, keeping South Platte and Arkansas tailwaters in the clear, wadable stage anglers count on through midsummer. Pat Dorsey Fly Fishing (CO) has flagged 2026 as one of Colorado's leanest water years on record, so stretches that run thin later this season are worth watching before wading deep. On the bug front, Gink and Gasoline points to the South Platte's reputation for dense morning trico spinner falls, a summer staple worth timing before the heat builds. Trout Unlimited's latest TROUT Tip leans into that same seasonal shift, noting terrestrials are now crawling the banks and getting eaten as big meals once they blow into the current. AvidMax Blog (CO) has been tying small tailwater midge and Euro-nymph patterns lately, a solid backup when the surface bite goes quiet. We're calling both rainbows and browns Active on light tippet and small profiles.
Warm-water trout shift to low-light bites on the Colorado River
This week's USGS reading (gauge 09095500) put area flow at 1,710 cfs with water pushing 77°F Saturday afternoon — warm enough to put trout on notice. Crystal Fly Shop (CO) describes the Colorado River between Glenwood Springs and Rifle as "on the back end of runoff," with golden stones, PMDs, and caddis already active and green drakes roughly two weeks out below Carbondale, though the shop flags that the good window closes once summer heat fully sets in. That heat is already a season-defining story: Pat Dorsey Fly Fishing (CO) calls 2026 one of Colorado's worst drought years on record, which tracks with the elevated temperature we're seeing now. Anglers Covey Blog (CO) notes rivers statewide are slowing into their "dog days" pace, with fish holding deeper and moving less during peak sun. Expect the best bites early and late, with midge and nymph patterns from AvidMax Blog (CO) staying relevant on tailwater stretches.
South Platte tricos click as Colorado tailwaters run low and clear
Trico spinner falls remain a hallmark of South Platte summer mornings. Gink and Gasoline still points to the river's dense trico activity as some of the best dry-fly action in the country, and it's a pattern worth planning around on early starts. No fresh buoy or gauge numbers came through for the South Platte or Arkansas this cycle, so plan on the typical low, clear, technical tailwater flows summer brings to both rivers. Pat Dorsey Fly Fishing (CO) has been flagging 2026 as one of Colorado's more significant drought years, which argues for careful wading and early starts before water warms. On the Dream Stream stretch, Colorado Trout Hunters notes this water still holds big, lake-run brown trout outside its classic fall and spring windows. AvidMax Blog's midge patterns built for clear, cold tailwater water are a sensible starting point on both rivers right now.
Colorado River trout dial in as runoff fades and drakes near
Flows on the Colorado River near Glenwood Springs are running around 2,640 cfs and dropping fast, and Crystal Fly Shop calls current conditions "great water conditions and happy fish" as the river clears out from spring runoff. On the Roaring Fork, the shop reports large attractor patterns working well in higher water below Carbondale, with green drakes expected to hatch in the next two weeks. The Crystal River is still shaking off runoff too, though the shop says "spectacular fishing" is only about a week away once flows keep dropping. Downstream on the low, clear Frying Pan, BWOs are hatching daily with PMDs starting to show, best worked with light 6X tippet during morning nymphing before afternoon dry-fly windows. Pat Dorsey Fly Fishing notes 2026 ranks among Colorado's driest years on record, a backdrop worth keeping in mind for flows and fish behavior across the Colorado and Arkansas systems this season.
South Platte tailwaters fish low and clear as trico season peaks
Colorado's tailwaters are heading into peak trico season on low, clear water. Gink and Gasoline recalls the South Platte's trico spinner falls as some of the densest bug activity in the state, with tricos so thick on the surface anglers can scoop dozens in a single pass, a pattern that repeats each summer on this stretch. That fishability comes against a backdrop of what Pat Dorsey Fly Fishing calls one of Colorado's worst droughts on record, with snowpack readings at historic lows heading into 2026. Cutthroat Anglers frames the low water as opportunity rather than crisis: fish are grouped up and still eager, rewarding anglers willing to hike farther and downsize tippet. Expect technical, low-and-clear tactics on South Platte and Arkansas tailwaters: small nymphs, careful wading, and morning windows before pressure builds.
Green Drakes Near as Runoff Clears Colorado's Western Slope Rivers
Runoff is finally loosening its grip on Colorado's Western Slope. Crystal Fly Shop clocks the Roaring Fork at 336 cfs at Aspen and 516 cfs at Basalt, dropping fast, while the Colorado River near Glenwood Springs still runs a strong 2,640 cfs on the back end of snowmelt. Large attractor patterns are drawing strikes in that higher water, nymphing has stayed solid on Rubberleg Stones and green drake imitations, and the shop expects the real green drake emergence below Carbondale in about two weeks. The Frying Pan, by contrast, is already low, clear and cold at 110 cfs, with daily blue-winged olive hatches and PMDs starting to show, best worked with morning nymphing and light 6X tippet. Against what Pat Dorsey Fly Fishing calls one of the worst snowpack years on record, Cutthroat Anglers reports fish are grouped up and still willing for anglers ready to hike farther and fish lighter. Brown and rainbow trout dominate this week's reports; native cutthroat aren't broken out separately, so we're rating that bite by season rather than direct testimony.
Fishing in Colorado
Colorado is trout country from border to border. Gold-medal rivers like the Fryingpan, the South Platte, and the Arkansas draw fly anglers from everywhere, high-country lakes hold cutthroats at elevations that take your breath away, and big reservoirs like Blue Mesa add lake trout and kokanee to the menu. If moving water and wild country are your thing, this is the state.
When to fish Colorado
Before the snowmelt blows the rivers out, there's a stretch of clear water and heavy feeding that river regulars circle on the calendar. The tailwaters below the dams stay fishable even through runoff, and the low-elevation lakes turn on early.
As runoff drops, everything comes into play: dry-fly hatches on the famous rivers, alpine lakes full of cutthroats, and kokanee and lake trout going deep on Blue Mesa. Long days make it easy to fish a river in the morning and a mountain lake by afternoon.
Brown trout get territorial and aggressive ahead of their fall spawn, and the summer crowds thin out just as the fishing peaks. Gold aspen over a quiet river is about as good as Colorado gets.
The dam-fed tailwaters on the South Platte and Fryingpan stay open and fishable all winter for anglers who like technical, small-fly work. Everywhere else, ice fishing takes over the reservoirs for trout, kokanee, and perch.

Common questions
Do I need a license to fish in Colorado?
Yes, a fishing license is required for most anglers. Colorado Parks & Wildlife sells them online, and regulations differ by water, especially on the gold-medal stretches, so check the current rules before you fish.
What fish can I catch in Colorado?
Trout are the headline: rainbows, browns, brookies, and native cutthroats across the rivers and high lakes. The reservoirs add lake trout, kokanee salmon, walleye, pike, and smallmouth, so there's more variety here than the fly-water reputation suggests.
When is the best time to fish Colorado?
Summer after runoff is the classic window, when the rivers clear and the high country opens. Fall brings aggressive brown trout and thin crowds, and the tailwaters keep quality fishing alive through the winter.
