Colorado fishing reports
142 reports for Colorado — what's biting, water temps, and where to focus.
Low, Clear Tailwaters Favor Small Flies as Drought Persists
Flow at USGS gauge 06701900 is running a modest 182 cfs, consistent with what Cutthroat Anglers (CO) and Pat Dorsey Fly Fishing (CO) are both flagging as one of Colorado's leanest water years on record. Pat Dorsey Fly Fishing (CO) puts 2026 among the worst droughts on record, while Cutthroat Anglers (CO) is urging anglers to carry a stream thermometer and stop fishing once water hits 68°F, since low flows push temperatures up earlier in the day. The upside, per Cutthroat Anglers (CO)'s Matt Campanella, is that fish are grouped up and still willing to eat for anglers who hike a little farther or downsize tippet. AvidMax Blog (CO)'s latest tying features, the Chocolate Foam Back and Titan Tube Midge, are built specifically for tailwater midge emergers, matching the small-fly game these clear, skinny flows are calling for right now.
Drought-stressed Colorado rivers push trout bite to dawn and tailwaters
The USGS gauge on the Colorado River is reading 73°F, well above the 68°F threshold Cutthroat Anglers flags as the point to stop fishing to protect stressed trout. It's part of a broader squeeze this year: Pat Dorsey Fly Fishing calls 2026 possibly the worst drought on record, and Crystal Fly Shop reports CPW voluntary closures already in effect on the Roaring Fork (noon-to-midnight) and Crystal River (full-day), plus a full-day closure on the Colorado River between Glenwood Springs and Rifle. Low, clear water is pushing fish off the banks and forcing smaller flies, per Crystal Fly Shop. Cutthroat Anglers notes the fish that remain are grouped up and still catchable for anglers willing to hike farther or fish lighter. Best bet right now: early mornings, tailwaters like the Frying Pan, and wrapping up before afternoon heat peaks.
South Platte, Arkansas tailwaters shift to early/late bite amid drought
Colorado's South Platte and Arkansas tailwaters are fishing through what Pat Dorsey Fly Fishing (CO) calls one of the worst droughts on record, and it's compressing the bite window. Cutthroat Anglers (CO) is reinforcing the standard advice to stop fishing once water hits 68°F, a mark arriving earlier in the day than typical for late August. Anglers Covey Blog (CO), guiding out of Colorado Springs near the Arkansas River drainage, describes the classic 'dog days' slowdown right on cue: rivers running slower, fish going lazier, activity concentrating into cool mornings and evenings. There's a brighter thread too — Colorado Trout Hunters reports the Dream Stream stretch of the South Platte produced one of its best migratory brown trout runs in recent memory this past year, which sets up real interest once fall temperatures start pulling the system down. For now, plan around early starts, carry a thermometer, and be ready to walk away from stressed water by midday.
Tailwater midges hold steady as Colorado's drought squeezes freestones
USGS gauge 06701900 is holding a steady 139 cfs as of Wednesday morning, and Colorado's dam-controlled trout water is settling into a classic August pattern: cool, stable releases while everything else in the state bakes. Pat Dorsey Fly Fishing calls the 2026 drought among the worst on record for Colorado, and Cutthroat Anglers is reinforcing hoot-owl discipline on freestone rivers, urging anglers to carry a thermometer and quit once water hits 68°F. Tailwaters like the South Platte and Arkansas are the beneficiaries of that stress right now, staying colder and clearer than freestones taking voluntary afternoon closures elsewhere in the state. AvidMax Blog's latest tying features, the Chocolate Foam Back and Titan Tube Midge, point straight at the bread-and-butter approach here: small midge patterns fished deep and slow. Anglers Covey Blog notes the "dog days" pace has settled over Colorado Springs-area water, so expect a technical, workmanlike bite rather than blow-up action. Fish early, fish small, and fish deep.
Drought Drops Colorado Rivers Low as Trout Bite Shifts to Mornings
The Roaring Fork is running low and clear at 113 cfs near Aspen's Jaffe Park and 410 cfs at Glenwood Springs, with flies sizing down as fish push off the banks into faster water, per Crystal Fly Shop. It's part of a statewide pattern: Pat Dorsey Fly Fishing calls the 2026 season possibly Colorado's worst drought on record, with snowpack below even the historic 1975-78 lows, and Cutthroat Anglers is telling anglers to carry a stream thermometer and stop fishing once water hits 68°F. CPW-enacted voluntary closures are now in effect on stretches of the Roaring Fork, Crystal, and Colorado Rivers, per Crystal Fly Shop, while the tailwater Frying Pan stays cold in the 40s below Ruedi Reservoir, keeping PMD, BWO, and Green Drake hatches firing into the afternoon. Trout remain active but grouped up in the remaining deep, cool water — Cutthroat Anglers' low-water tips favor hiking farther for concentrated fish over working closed water.
Dream Stream browns stir as CO tailwaters manage summer heat
Colorado's South Platte and Arkansas tailwaters are running low, clear, and warm this August, and shops along the Front Range are urging anglers to fish early and quit before the heat peaks. Cutthroat Anglers (CO) is telling clients to stop once water hits 68°F, a mark landing earlier in the day during what Pat Dorsey Fly Fishing (CO) calls one of the worst drought years on record for the state. Wired 2 Fish reports fish and wildlife agencies across the West are increasingly asking anglers to lay off cold-water species during the hottest hours, with voluntary afternoon closures already in effect on other Colorado rivers, per Crystal Fly Shop (CO). There's an upside: Colorado Trout Hunters notes the Dream Stream stretch of the South Platte has produced one of its best migratory-brown runs in years, and low water is grouping fish tightly, per Cutthroat Anglers, concentrating bites for anglers willing to hike to remaining cold refuges and downsize their rigs.
Low, clear water pushes Colorado trout into tight pockets
Colorado's freestone rivers are running low and clear as the state works through what Pat Dorsey Fly Fishing calls one of the worst droughts on record. Crystal Fly Shop (CO) reports a voluntary afternoon closure on the Roaring Fork (Highway 133 bridge in Carbondale down to the Colorado River confluence) and a full-day closure on the lower Crystal River as managers try to protect stressed fish, while the Frying Pan stays cold and fishable below Ruedi Reservoir thanks to dam-controlled release temps in the 40s. Cutthroat Anglers (CO) is urging anglers to carry a thermometer and stop fishing once water hits 68°F. Despite the tough headlines, Matt Campanella's low-water tips via Cutthroat Anglers (CO) note fish are grouped up and still biting for anglers willing to hike farther and downsize their approach. Anglers Covey Blog (CO) calls it classic dog-days pace: slower rivers, lazier fish, more patience required.
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.
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.
