Colorado fishing reports
186 reports for Colorado — what's biting, water temps, and where to focus.
Colorado River conditions prime as runoff fades and green drakes approach
Crystal Fly Shop (CO) is calling it now: the Colorado River from Glenwood Springs to Rifle is on the back end of runoff at 2,640 cfs with great water clarity and active fish. Their advice is to get on the water before summer heat arrives and the fishing tapers. Green drakes, golden stones, and PMDs are expected to come into full force within the next two weeks, making this the setup window serious dry-fly anglers should not miss. Overcast days will produce the best surface action on the Colorado. Cutthroat Anglers (CO) adds important context: 2026's historic low Western snowpacks have compressed and accelerated runoff timelines across the state, concentrating trout in key lies and creating low-water conditions that reward technical presentations and light tippets. On the upper Colorado system, Wired 2 Fish reports that Colorado Parks and Wildlife is running a paid pike removal tournament at Green Mountain Reservoir through September 30. Anglers can earn up to $500 per month targeting invasive northern pike. Specific Arkansas River intel was not available in this cycle.
Trico season and low water converge on Colorado's Gold Medal tailwaters
Cutthroat Anglers (CO) did not mince words this spring: 'There is no sugar coating the fact Colorado snowpack is historically bad and we face a much different season this year.' Guide Matt Campanella flips the narrative, noting that low flows concentrate fish and create opportunity for anglers willing to 'hike a little further or cast a little lighter.' Colorado Trout Hunters reports the Dream Stream section of the South Platte delivered one of its best spring migratory fish runs in recent memory — a strong sign heading into the summer tailwater season. On the pattern front, AvidMax Blog (CO) has been spotlighting midge emergers and slim tube midge designs as the workhorses for tailwater trout in clear, low conditions, a fitting frame for late June when both the South Platte and Arkansas run gin-clear. No USGS gauge data was available for this update; confirm current releases before making the drive.
Colorado trout fishing hits its stride as runoff winds down
USGS gauge 09095500 logged 2,180 cfs and 68°F on the Colorado River on June 27, placing water temps right at the upper comfort threshold for trout. Early-morning and evening windows are the priority. Crystal Fly Shop (CO) puts it plainly: the Colorado is 'on the back end of runoff now with currently great water conditions and happy fish,' and advises anglers to take advantage before midsummer heat tapers the bite. Large attractor patterns are delivering in still-elevated flows, while Rubberleg Stones and green drake nymphs have been productive sub-surface, per Crystal Fly Shop (CO). Green drakes, golden stones, PMDs, and caddis are all expected to peak within the next two weeks. Cutthroat Anglers (CO) note that Colorado's historically low 2026 snowpack, though worrying for long-term flows, has concentrated fish in remaining holding water, rewarding anglers willing to adapt their approach and cover less water more carefully.
Trico season arrives on Colorado's South Platte as tailwaters run low and clear
Colorado Trout Hunters reported one of the best spring runs of migratory lake-run fish on the Dream Stream in recent memory, and that momentum carries into late June. The backdrop, however, is a challenging one: Cutthroat Anglers notes that Western snowpacks hit historic lows this winter, leaving South Platte and Arkansas tailwater flows lean and exceptionally clear. Per Cutthroat Anglers' Matt Campanella, low water concentrates fish into tighter, more defined lies, a tactical advantage for anglers willing to hike past easy-access water and commit to light, precise presentations. AvidMax Blog has been tying Titan Tube Midges and Chocolate Foam Back emergers specifically for the clear, cold conditions that tailwater trout demand. With trico spinner falls historically among the densest on the South Platte corridor, and late June marking the traditional start of that hatch, the next several weeks could offer some of the year's best dry-fly opportunities for anglers willing to size down and slow down.
Colorado trout in prime window as runoff clears and hatches build
Crystal Fly Shop calls it plainly: the Colorado River is on 'the back end of runoff now with currently great water conditions and happy fish,' urging anglers not to wait. Running at 2,640 cfs near Glenwood Springs, flows remain elevated but are dropping steadily, and green drakes are expected to fire within two weeks alongside golden stones, PMDs, and caddis. Cutthroat Anglers notes that this season's historically poor Western snowpack has moved the runoff timeline earlier than normal, meaning the transition to summer fishing patterns is already underway. The silver lining, per Cutthroat Anglers: fish are active, well-grouped in fishable water, and responding to well-presented flies. The Arkansas River, sharing the same drought-year dynamics, should be clearing similarly. Wired 2 Fish reports that Colorado Parks and Wildlife is deploying Trojan YY brook trout to displace invasive brookies and restore native cutthroat populations — a conservation story to follow across these drainages.
Low flows concentrate South Platte and Arkansas trout as summer hatches build
Colorado's historically low 2026 snowpack is running the South Platte and Arkansas tailwaters lean and clear heading into peak summer. Cutthroat Anglers' guide Matt Campanella sees the upside: with more than 60% of the Lower 48 in drought, fish have consolidated into deeper holds where they are "active, grouped up, and ready to bite" for anglers willing to adapt. On the South Platte, Colorado Trout Hunters reports one of the best spring migratory runs on the Dream Stream section in recent memory, with trophy-class lake-run fish moving through the Spinney Mountain stretch. As late June arrives, trico season is coming into range. Gink and Gasoline calls the South Platte's spinner falls among the most striking in the West, with dense clouds of spinners blanketing the surface. Midges remain the year-round anchor on both tailwaters; AvidMax Blog is highlighting emerger and tube midge patterns designed for clear, technical tailwater conditions. Plan for fine tippet and precise presentations.
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.
