Boulder Creek Fishing Report – November 2024
November on Boulder Creek brings classic late-fall conditions—crisp mornings, low flows, and eager trout. The creek is flowing at around 15-20 CFS, making it easy to wade but requiring stealth. Trout are concentrated in deeper pools and slower runs, especially as the water cools. With midges and occasional Blue Wing Olives hatching, this time of year is perfect for those who enjoy nymphing, with some small dry fly action in the afternoons.
Boulder Creek’s wild browns and rainbows are known for being active in colder months, especially with the right presentations. Midday is the sweet spot, as trout are more likely to rise to the surface in the warmer sunlight. While it’s a bit technical, Boulder Creek in November offers rewarding fishing with light tackle, small flies, and a stealthy approach.

Tips Fly Fishing on Boulder Creek
-1.png?width=600&height=400&name=fly%20fishing%20in%20colorado%20(49)-1.png)
Seasonal Tip
During cooler weather, aim for fishing during the warmest part of the day. Look for trout holding in deeper pools or slow-moving sections, and approach quietly to avoid spooking them.
Dry Fly
If you see a midday hatch, small BWOs are effective. Focus on slow pools and runs where trout rise cautiously in clear water.
Nymphing
A double-nymph rig with a Black Beauty and small midge pattern will produce well. Drift through riffles and tailouts, where trout stay active and feed near the bottom.
Streamer Fishing
Mini leeches or small Woolly Buggers are great for targeting larger fish. Work slowly through the deeper sections to draw out any lingering big browns.
