Flows are in the sweet spot for the Ark. The Upper Basin from Leadville to Buena Vista is at a very wadeable level. Hoppers, beetles, caddis, PMD's and BWO's are all doing their fare share to keep these fish fed. A dry dropper rig is the most effective way to cover river up there. Focus your efforts on the deeper runs in the early part of the day. As the day warms up, fish will transition to riffles and feeling lanes, i.e. foam lines, undercuts, shadow lines, overhangs and the tailout of runs. Depending on the weather the hatches this time of year tend to be a little sparser. Some leftover caddis in the morning along with BWO's if the temps drop low enough. As it warms up PMD's tend to be the most readily available followed closely by hoppers and beetles. Caddis will again become prevalent starting after 3pm. Lower down the Ark, flows are hanging on the threshold to float, hovering around 500. Fish are still closer to the banks with the higher flows. Hoppers have replaced stones as the large topwater meal. Still a bit dicy to wade at this level but bank fishing has been stellar. As flows continue to drop making your way into Brown's Canyon can be great way to spend a day fishing. This wild browns are willing to come to the fly and when in the mood can chase streamers viciously. Look for the Ark to be an over-producer as we work out way into Fall. The good water flows will keep this river fishing well into late October and early November. Some spectacular caddis hatches happen later in the fall as well as BWO's and terrestrials. The Ark is in shape, get up there!

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
