Fishing on the St. Vrain has been fair to good, but a lot of reports coming back of high pressure on the South Vrain and slower fishing along with it. Just like Boulder Creek, try putting in a little effort and hitting the hole that doesn't see 15 anglers every day. Look for the best pull-off on the river, and then keep on driving. Or, stop in that spot, and walk down or up a little bit and wedge yourself between two separate pull-offs. This spot will get the least pressure. With all the pressure, you may need to hit up a new spot and learn a new hole or 2.a good problem to have. Try to get out a little bit earlier, or even a little bit later in the afternoons/evenings and the fishing should pick up at those times. The usual St. Vrain hatches are on Caddis, Stones and some PMDs. Seeing lots of midges as well throughout the day. I recommend some smaller dries on the south and even try throwing that fly that has been in your box for a while just staring at you that you never give any love to. The fish most likely haven't seen that fly in a while and will be anxious to eat it to see if it still tastes the same. Also, try the North St. Vrain below Button Rock; the weekdays are always a good bet and if you hike around to the inlet you will most certainly be awarded for your efforts. Again, just put in the time and the trout will pay the crime. Tight Lines-

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
