Summary

Best access is from multiple pull-offs along Highway 103, with prime spots near shaded bends and deeper pools. There’s no boat or pier access—fishing is entirely from shore. The creek supports rainbow trout, brown trout, and brook trout. Fly fishing with nymphs, streamers, or dry flies works well, especially in spring and early summer. Spinners and small spoons also produce results. Trout are most active in the morning and evening. The area is stocked regularly, making it ideal for family-friendly fishing close to Denver.

Angling Safety Guidelines

Know the Regulations
Check local fishing rules, seasons, size limits, and license requirements to ensure legal and sustainable angling.
Handle Fish Responsibly
Use wet hands, minimize air exposure, and release fish gently to improve survival rates when practicing catch-and-release.
Choose the Right Gear
Match your rod, line, and tackle to the species and conditions to increase success and reduce unnecessary harm to fish.
Respect the Waterway
Avoid disturbing habitat, prevent bank erosion, and keep a safe distance from spawning areas to protect ecosystems.
Keep It Clean
Pack out all line, hooks, bait containers, and trash—discarded gear can injure wildlife and degrade waterways.
