The Beaverhead is a challenging river that rewards those with great skill and leaves some humbled at the end of their day on the river for a lot of the year. Once the rivers Pale Morning Duns start to hatch from the third week of June to early July throughout the summer, things get a lot easier. Even good guides that are humbled by the rivers quirkiness in the off season know that once the PMDs start to hatch. this is the place to be. The bugs are coming off in limited numbers right now, a few big fish are eating the dries and the rest are locking in on the nymph drift. Expect increasing numbers of PMDs to hatch, with the emergence of strong Yellow Sally hatches from lunch time through the afternoon. Cooler water temps have limited hatches thus far, but summer wont wait forever. Stop in and ask our advice about hot flies, things are leveling out, but they change daily.
The Big Hole is still awaiting the emergence of great dry fly fishing with Golden Stoneflies. Below average temperatures in the latter half of June slowed down the usual daytime flurry of multiple hatches, but water temperatures have normalized and the river is fishing well in the clouds, slower in the sun.
The Jefferson provided a short but sweet window of great fishing before the moss began to flow. Quickly dropping flows caused a lot to break loose and clog leaders and flies. The stringy green stuff will slow down and fishing will improve as flows stabilize. Run to the Jefferson on cloudy days and fish shiny olive stuff and smaller bugs in the sun.
Warming longe range temperatures will concentrate fish at Clark Canyon Reservoir at the South end, find the river channel and fish chironomids and sheep creeks. Shiny bugs work best on sunny days.
