Beaver creek of the South Fork of the Rio Grande is a technical little stream that proved to be the most challenging out of all the feeder creeks (park and pass creek). Fish seemed to be smaller and harder to catch, but in a way that made it almost more fun. You need a good drift to catch this fish as they were refusing a lot of my drifts until I added more slack and did some pile casts. Then they seemed to be more keen on my offerings. It was a beautiful little stream and if you are seeking solitude, beautiful water to fish, and a medium challenge for some beautiful fish, this place is a great place to spend a day or a weekend. With lots of water nearby, you can always change it up and fish elsewhere if you find the fishing isn’t what you wanted. Great camping, wildlife and scenery is available on this stretch of creek and is worth the time taken to explore it.

Beaver Creek of South Fork of Rio Grande River Fishing Information
Main Section - near South Fork, CO
A dry dropper during the summer months is your best bet here. A double dry is also good if you want to focus just on dries, but two flies here help improve the odds. Try to mix up species (caddis up front, mayfly behind) as the fish can be a little picky and finding the right bug is important. A good presentation will bring it home, but focus around caddis, green drakes, pmd, and other small mayflies and midges in 14 – 18. I like a missing link caddis followed by a CDC caddis emerger for waters like this as they are imitative enough to fool trout but search pattern enough to cover your gaps you may have.
