On really windy days, a bigger hopper or cricket can be killer. Scud and sowbug patterns are another good choice when there is minimal hatch activity. Yellowstone River Flows are still very low on most rivers in the area, including the Yellowstone, but cooler weather and some much needed precipitation have improved fishing conditions tremendously. Fishing technique in the next couple of weeks will be dictated by weather. On cooler, overcast days, expect to see afternoon hatches of Baetis mayflies.
Streamer patterns are effective in low light periods early and late and on overcast days.
These are best fished on a sink-tip line and short leader when fishing from a drift boat. The main Boulder has continued to fish well in recent weeks. A short drive from Livingston, the Boulder is a wonderful mountain freestone stream that offers some very nice fishing in a spectacular setting. The access on the upper main Boulder is quite good, up inside the National Forest. There are many Forest Service campgrounds and access sites, starting about five miles above the falls.
