We've hit the point in the winter where the south branch of the St. Vrain is mostly out of play, but there's some decent fishing down towards town and over on the north branch. The Button Rock Trailhead access is a good option. Look for the patches of water with depth and ideally some sun, and try leading with a small worm as an attractor and dropping down to a midge of some kind. You can expect to catch a majority of your fish sub-surface, but on warm days fish are looking up to the surface for midges and smaller mayflies. Nymphing deeper pools, slow and low will also be a way to catch. We have been sizing down our tippets and that has been key! 5 and 6x works real good! Fluorocarbon isn't usually necessary in spring/summer/fall on most of the St. Vrain, but it can really help when nymphing small bugs in the wintertime.

The Ultimate Fly Fishing Report
Casting a fly in a tranquil mountain stream, feeling the tug on the line, and holding a beautiful rainbow trout makes us feel alive and intensely connected with nature. Fly fishing is our way of life and we are blessed with hundreds of nearby rivers and streams just a short distance away from Boulder. From the swift spring waters of the Clear Creek to the meandering bends of the South Platte, it's critical to consider fishing conditions in advance and prepare accordingly. We rely on our experienced guides who venture into the wild to let us know which rivers favor fly fishing, where fish are biting, and which fly patterns are most effective. Planning a successful fishing trip also requires knowledge of stream flows at various river points and an accurate weather forecast for a given destination. At Rocky Mountain Anglers, we are dedicated to providing all avid anglers with detailed and timely information about hatches, water, and weather conditions. So before you head out the door on your next fishing adventure, visit our web site to find valuable information that will prepare you for a successful trip. Have fun chasing after your next trophy trout and enjoy nature's beauty!The Rocky Mountain Anglers Crew
