Species matches to consider
Outside this date's researched outing window
These are species matches, not recommended open-water outings for the selected date. A seasonal window is not a legal opening date or proof that fish are absent.
Species reported, but not a strong target recommendation
These are alternatives to investigate, not extra recommendations added to fill the list.

Walking categories describe the named access under normal open-road conditions. Roadside / park access can include nearby paths, but not a separate trail excursion or documented steep descent. Short walks use a separate approach trail; hikes include longer trails and steep descents, even beside a road. Unknown approaches appear only when you are happy to hike and remain labeled unverified. Snow, gates and road closures can change the actual approach. Walking classifications were reviewed 2026-09-30; no category guarantees accessible terrain or safe wading.
We separate official fishery evidence, secondary guide recommendations, and mere species presence. For your date, sourced seasonal fit comes first, then evidence strength. This is editorial order, not a calculated catch probability. Without an account you can reveal a set number of matching outings per species in this browser, shared with its species guide. Each search spends what is left of that number on what it matched; a search that matches nothing spends nothing, and a search you have already run costs nothing again. A free account raises that number for every species and refreshes it on every search; Pro reaches every researched outing. We never relax filters to fill the list. Counties without research stay visible in the dropdown with zero counts.
Some sources establish year-round fishing or useful months; others do not. We label unknown seasonal timing rather than inventing a peak. Future trips use seasonal guidance, not today's flow as a forecast. All rules, road access, weather, closures and water temperatures need rechecking before departure.
Gauge data attach only to the configured reach. Missing, stale or unavailable data never mean good conditions. For today's trip, notices, heat and adverse flow move a target out of recommendations. For future dates, unresolved reach notices still require review, but current heat/flow does not predict your trip. Ungauged destinations need a local conditions and closure check.
TroutTips starts flagging heat at 67°F; CPW advises moving elsewhere at 70°F. Carry a thermometer, respect voluntary and mandatory restrictions, and avoid disturbing spawning fish or their beds. CPW fishing and conservation guidance.

What CPW found in the lakes
Gill-net counts and fish sizes from Colorado Parks and Wildlife surveys of 44 lakes in this catalog: how many fish were in the net, which species, how big, and what CPW has stocked. A survey count is not a catch rate.
- A pink or red side stripe is common, but lake fish can look much more silver.
- Dark spots extend across the back, sides and tail.
- Compare the whole fish, not just the stripe: Cutthroat and hybrids can share similar colors.
Color varies with habitat and life stage. A photograph alone is not a reliable way to rule out a Cutthroat–Rainbow hybrid.
- Look for pale, worm-like markings on the dark back and dorsal fin.
- Red spots often have bluish halos, alongside lighter spots on the body.
- Lower fins have a white leading edge; the tail is nearly square or only slightly forked.
The bright belly in this illustration is not present on every fish. Use the markings and fin edges together.
- Look for red or orange slashes beneath the lower jaw.
- Dark spotting is often more concentrated toward the tail; body colors vary.
- A throat slash alone does not establish subspecies or genetic purity: Cutthroat can hybridize with Rainbow Trout.
The illustration shows a Bonneville Cutthroat, not a Colorado subspecies example or proof of the fish found at any listed outing. Color and spotting vary among Cutthroat. Cutbow hybrids are not counted as pure Cutthroat targets.
- Dark brown or black spots, often with red spots, sit on a lighter brown, gold or olive body.
- Many spots have pale halos around them.
- The tail usually has few or no spots, unlike the heavily spotted tail typical of Rainbow Trout.
Body color alone is not enough. Compare the spot pattern and tail, and remember that individual fish vary.
- Outside spawning condition, the body is silvery with a blue-green back.
- There is no distinct Rainbow-like spotting pattern on the tail and dorsal fin.
- During spawning, the body turns red and the head darkens toward green; males can develop a pronounced hump and hooked jaw.
The silver-form and spawning-male illustrations show different life stages, not two species. Neither image indicates a current spawning run.
- A small mouth sits below a pointed snout.
- Large, conspicuous scales cover the silvery sides.
- Look for a deeply forked tail; the grayish-blue back fades to a whitish belly.
Use the mouth, scales and tail together rather than identifying a fish from its silver color alone. This reference illustration is not a current Colorado catch report.
