Colorado fishing reports
60 reports for Colorado — what's biting, water temps, and where to focus.
Post-runoff window opens on the Colorado River as green drakes approach
Crystal Fly Shop (CO) reports the Colorado River is 'on the back end of runoff now with currently great water conditions and happy fish' — the window to fish is open right now, before summer heat tightens things further. USGS gauge 09095500 recorded 2,210 cfs and a 71°F water temperature on June 22, putting the river at the upper edge of comfortable trout habitat. At this temp, trout are still feeding actively but shift toward deeper, cooler runs and shaded seams as midday arrives; morning sessions are the priority. Cutthroat Anglers (CO) frames the 2026 season plainly: fish are 'grouped up, and ready to bite for the angler willing to hike a little further or cast a little lighter.' Green drakes are the headline hatch on deck, with Crystal Fly Shop projecting a full-force emergence in the coming two weeks. Golden stones, PMDs, and caddis round out the menu. Large attractor patterns are fishing well in the higher water. On the Arkansas River, expect similar late-runoff conditions with the same early-window advantage.
Front Range tailwaters primed for summer as trico season kicks off
Colorado Trout Hunters reports one of the best spring runs of migratory fish the Dream Stream has seen in recent memory, a promising sign heading into summer on the South Platte. The USGS gauge at site 06701900 is reading 277 cfs as of midday June 22 — a moderate, wadeable flow for this regulated tailwater, with no water temperature reading currently available. Cutthroat Anglers cautions that 2026's Colorado snowpack has been "historic for all the wrong reasons," with drought pushing statewide conditions toward low-water patterns even on tailwater drainages; their low-water pro tips urge lighter tippet and precise presentations to reach fish concentrated in defined lies. Late June traditionally signals the start of the trico spinner fall on the South Platte — Gink and Gasoline describes the river's trico hatch as one of the most prolific on record — and that window is now opening. Midges and PMD imitations continue to anchor nymph rigs through morning hours on both drainages.
Colorado River trout firing as runoff fades — green drakes and golden stones incoming
Crystal Fly Shop (CO) is calling the Colorado River from Glenwood Springs to Rifle one of the best windows of the season right now — runoff is on its back end, water conditions are excellent, and fish are active. Large attractor patterns are producing, with green drakes expected "right on the horizon in the next two weeks," joined by golden stones, PMDs, and caddis. Overcast days are flagged as the prime window. The Frying Pan River, a reliable tailwater tributary feeding into this drainage, is running low, clear, and cold with consistent BWO and PMD hatches each afternoon, per Crystal Fly Shop. Across Colorado's high country, Cutthroat Anglers (CO) is direct about 2026: snowpack was historically bad, and rivers are tracking well below normal for late June — the upside being that remaining fish are concentrated and willing to eat. No direct Arkansas River shop reports are available this week; the statewide low-snowpack context applies.
Drought-thinned tailwaters concentrate South Platte and Arkansas trout
Cutthroat Anglers is flagging historically bad 2026 Colorado snowpack, with western drought touching more than 60% of the Lower 48, but guide Matt Campanella notes fish have adapted: low-water trout are "active, grouped up, and ready to bite" for anglers willing to hike a little farther and cast a little lighter. Colorado Trout Hunters reports one of the strongest spring migratory runs on the Dream Stream stretch of the South Platte "in quite some time," with sizable lake-run browns drawing trophy hunters into the early summer window. Crystal Fly Shop's current Frying Pan tailwater report, a close regional analogue, confirms the low-clear-cold template: BWOs and PMDs hatching daily, midges throughout, and 6X fluorocarbon the standard call. AvidMax has been spotlighting midge emerger and tube-midge patterns built specifically for tailrace pressure. With the summer solstice now passed, trico spinner falls, a hallmark South Platte event detailed by Gink and Gasoline, should be ramping up through late June and into July.
Post-runoff prime window opens on the Colorado River
Crystal Fly Shop (CO) is calling it: the Colorado River is on the back end of runoff with "great water conditions and happy fish." USGS gauge 09095500 confirms the Colorado running at 2,720 cfs and 67°F as of June 17 — right at the warm edge of the prime trout window. Crystal Fly Shop urges anglers to get out now, before summer heat tapers the bite, noting green drakes are expected to emerge in full force within two weeks along the Colorado corridor. Golden stoneflies, PMDs, and caddis are already in play, with overcast days particularly productive for dry-fly fishing. On the Arkansas River and across the broader Colorado drainage, Cutthroat Anglers (CO) reports that despite a historically low snowpack this season, trout are "active, grouped up, and ready to bite" for anglers willing to downsize flies and fish lighter tippets. Plan sessions for early mornings and evenings, as 67°F water temps can push fish into shade and deeper slots during midday heat.
Dream Stream fires mid-June as drought concentrates South Platte tailwater fish
Colorado Trout Hunters report one of the best spring runs of large migratory lake-run fish on the South Platte's Dream Stream in recent memory, making mid-June a prime window for tailwater regulars. USGS gauge 06701900 recorded 246 cfs on the South Platte as of early morning June 17, a manageable wading flow that is working in anglers' favor. Cutthroat Anglers' Matt Campanella notes that while 2026 Colorado snowpack hit historic lows, low-water conditions concentrate fish and reward adaptable anglers willing to refine their approach. Hatch Magazine reinforces that veteran Front Range trout anglers are well-practiced at fishing through drought years, and this season is no exception. AvidMax Blog's recent tying features highlight the patterns carrying tailwater days right now: midge emergers like the Chocolate Foam Back and the Titan Tube Midge, fished just under the surface film, are the consistent producers. Nymphing through mid-morning and targeting seams during afternoon midge hatches is the play.
Colorado River clears from runoff as green drakes and golden stones build
Water at USGS gauge 09095500 is running 2,850 cfs and 69°F on the Colorado River as of June 16 — warm enough to flag caution with trout handling and make early-morning starts non-negotiable. Crystal Fly Shop calls this the moment to be on the water: 'We're on the back end of runoff now with currently great water conditions and happy fish,' urging float trips before summer heat tightens the window. Green drakes are expected within two weeks below Carbondale, per Crystal Fly Shop, with golden stones, PMDs, and caddis also building toward their peak. Cutthroat Anglers points out that Colorado's historically poor 2026 snowpack has fish 'grouped up and ready to bite' in predictable lies — a real tactical advantage for the angler willing to slow down and read the water. At 69°F, trout are approaching their stress threshold; fish first light and handle quickly. The New Moon favors low-light feeding windows at dawn and dusk.
Dream Stream delivers strong spring migratory run despite Front Range drought
Colorado Trout Hunters is reporting one of the best spring runs of migratory fish on the Dream Stream section of the South Platte in recent memory — a notable bright spot in a drought-stricken season. USGS gauge 06701900 recorded 258 cfs on June 16, reflecting the historically low snowpack that Cutthroat Anglers (CO) calls "historic for all the wrong reasons" in their 2026 season outlook. Per Cutthroat Anglers' low-water tips post by Matt Campanella, those reduced flows also concentrate fish into tighter lies, creating focused opportunities for adaptable anglers willing to cast a little lighter and hike a little further. On comparable Colorado tailwaters, Crystal Fly Shop is reporting reliable BWO hatches each day, with PMDs appearing over the past week and midges and caddis rounding out the mix. Hatch Magazine specifically flags Colorado's Front Range as a region where low, clear drought flows demand lighter tippets and more precise presentations — a thread running through every local report this season.
Colorado breaks from runoff early as green drakes and golden stones approach
Crystal Fly Shop reports the Colorado River at Glenwood Springs is on the back end of runoff with 'currently great water conditions and happy fish' — the float-fishing window is open now before summer heat tightens things up. Green drakes, golden stones, PMDs, and caddis are queued to emerge within the next two weeks on the main stem, while the Frying Pan tailwater (110 cfs below Ruedi Reservoir) is already fishing reliably with daily BWO and PMD hatches; Crystal Fly Shop recommends 6X fluorocarbon and morning nymphing until afternoon dries come on. Large attractor patterns are producing in still-elevated flows. Cutthroat Anglers (CO) sets the broader context: Colorado's snowpack landed at historic lows this season, meaning flows across both the Colorado and Arkansas drainages will taper earlier and faster than normal. The upside, as Cutthroat Anglers puts it, is that fish are 'active, grouped up, and ready to bite' in concentrated lies for anglers willing to adapt.
Dream Stream run wraps as drought-year low water locks in across CO tailwaters
Colorado Trout Hunters reported one of the best spring migratory runs they've seen on the Dream Stream (South Platte) in recent memory, with large lake-run browns drawing experienced anglers to the stretch through late May. That run has now wound down, and both the South Platte and Arkansas tailwaters are settling into a summer low-water pattern shaped by a drought year. Cutthroat Anglers flagged that Colorado's snowpack was "historically bad" this winter, translating to lower, clearer flows across the board. The upside, per Cutthroat Anglers guide Matt Campanella: fish are concentrated and willing to eat for anglers who scale down their presentation. Midge patterns remain the tailwater staple, with AvidMax Blog highlighting the Chocolate Foam Back emerger and Titan Tube Midge as top choices in clear, pressured water. Tonight's New Moon keeps ambient light low through the coming week, favoring low-light feeding windows at dawn and dusk.
Prime trout window opens on Colorado and Arkansas Rivers as runoff clears
With the USGS gauge at 2,740 cfs and water temperature at 68°F, the Colorado River is cresting out of spring runoff and entering a brief but genuine fishing window. Crystal Fly Shop (CO) said it plainly: "We're on the back end of runoff now with currently great water conditions and happy fish — the time to float and fish the river is NOW before the heat kicks in." Large attractor patterns are producing in the elevated flows, and the shop expects green drakes within two weeks, followed by golden stones, PMDs, and caddis. One caution: 68°F is at the upper edge of trout thermal tolerance, and Field & Stream's temperature guide notes that wildlife agencies often implement hoot owl restrictions near these readings. Target early mornings and overcast afternoons for the best action. Cutthroat Anglers (CO) add that Colorado's historically low 2026 snowpack has compressed this season's timeline, but fish are "grouped up and ready to bite for the adaptable angler." This window is short — plan accordingly.
Prime post-runoff window opens on the Colorado as green drakes loom
Water temps have climbed to 67°F on the Colorado River (USGS gauge 09095500), signaling an urgent fishing window before summer heat tightens the thermal squeeze on trout. Crystal Fly Shop reports 'currently great water conditions and happy fish' on the Colorado River corridor, urging anglers not to wait: the time to float and fish is now. Green drakes are expected within two weeks below Carbondale, with golden stones, PMDs, and caddis already in rotation. Large attractor dries are producing in the slightly elevated flows, while nymphing with Rubberleg Stones and green drake imitations has been solid. Cutthroat Anglers notes that this year's historically poor Colorado snowpack has concentrated fish, making them 'active, grouped up, and ready to bite for the angler willing to hike a little further or cast a little lighter.' With 67°F readings and climbing daytime air temps, plan early-morning and evening sessions to keep fish healthy on the release.
