Clear Creek: Where the Fish Are Feisty, and the Hatches Are Fast

Clear Creek is the working-class hero of Colorado fly fishing. It doesn’t ask for much—just a good drift, a decent bug, and a little patience. From high-alpine headwaters near Loveland Pass to the canyon stretches west of Golden, Clear Creek is tight, fast, cold, and surprisingly productive.

While the fish aren’t picky by Cheesman standards, they still care about what’s hatching. Especially in the shoulder seasons when flows are low and food is scarce. That’s where this hatch chart comes in.

Whether you're tightlining stoneflies in June or drifting midges under the I-70 bridge in January, matching the hatch makes the difference between a “quick walk with your rod” and a net full of wild browns.

The Ark’s Bugs Change Fast—Stay Sharp

This river's a study in contrasts. At 10,000 feet, midges rule. In Bighorn Sheep Canyon, it’s hoppers and stoneflies. Always check flows, match size first, and fish the water in front of you—not the hatch chart in your pocket. Then go back and match both.
