Colorado River Autumn Bliss: Trout, Foliage, and Ideal Fishing Conditions
Artificial Lure here with your Colorado River fishing report for Saturday, September 27, 2025. The calendar says early fall, and the river is wearing its autumn best: chilly mornings, vibrant foliage along the banks—leaf-peepers and anglers alike are loving it. According to a recent forecast from USA Today and The Weather Network, we’ve been treated to classic Colorado bluebird weather: highs near 79°F today, crisp mornings in the upper 40s, and practically no wind to hamper a good cast. Sunrise hit at 6:51 a.m., sunset is set for 6:51 p.m.—so plenty of daylight to wet your line.
While the Colorado proper doesn't see ocean tides, the flow and temperature variations are just as important. Upstream releases have been pretty stable this week, with flows on nearby rivers like the Arkansas running wade-friendly and clarity good, signaling similar ideal conditions on much of the mainstem Colorado. The river’s running clear and cool in the mornings, warming by midday, so fish are most active right around dawn and again in the evening, when water temps are prime and bug hatches ramp up.
Recent reports along the upper stretches—think the Parshall bend, Radium, up toward Kremmling—show trout are on the feed. Rainbows and browns are taking advantage of prolific morning trico hatches, followed by caddis and blue-wing olive mayflies as the sun climbs. The best bite is between first light and 10:30 a.m.—by noon, trout are tucking into deeper runs to wait out the midday sun.
Guides from The Drift Fly Shop and North Park Anglers are seeing good numbers of healthy bows and browns, with the occasional cutthroat and even kokanee salmon nosing upriver if you’re near a tributary. Most nets today are averaging a half-dozen or more fish per trip, with some boats reporting a dozen if you hit the hatch just right.
For tackle, it’s hard to beat classic Colorado autumn fare:
- **Best lures:** #18-20 Trico spinners, parachute Adams, small blue-wing olive dries, beadhead pheasant tails, zebra midges under an indicator.
- **Best bait:** Artificial-only sections are common, but where bait is allowed, drifting a nightcrawler or salmon egg through a deep pool might tempt a bruiser brown.
- Don’t forget streamers—small olive or black leech patterns and white buggers are taking fish as light changes, especially at dawn and dusk.
A couple of hot spots to try: The Copper Bar stretch below State Bridge and the runs above Pump House are producing solid numbers. For those seeking less pressure, work the seams around Radium—deep buckets below riffles are holding fat trout.
Colorado’s peak foliage is making this weekend even more special according to Unofficial Networks, with gold aspens and fiery maples at their best. A float or walk along the river right now is something you don’t want to miss.
Keep an eye on the weather Sunday as a shift may bring some showers, but Saturday’s all clear for action. Whether you’re hunting trout with dries at sunrise or swinging streamers in the evening cool, the bite’s on and the Colorado River is open for business.
