Get out to enjoy the last few weeks of fishing effective terrestrial patterns. That’s because by mid October killing frosts are sure to come and impact the terrestrial insect population. Then if you are a dry fly person, BWOs on such as the Firehole, Gibbon and Madison will be almost all that is left. After that streamers will be the way to go on just about all streams and on many lakes, especially those hosting brown trout.
A few Hebgen lake browns & bows are showing up in the Madison River inside the Park. Likewise, browns are beginning to move in the Lewis River system. Best place to find these are in the river between Lewis & Shoshone lakes and at the Lewis Lake outlet. Action on the Firehole River is picking up thanks to cooling waters and BWO and caddisflies. Terrestrrial patterns remain effective on all Fall River Basin streams and on those of the Lamar River drainage at the northeast corner of the Park. The Gallatin River remains a good choice for presenting classic attractor patterns. The fastest action in Park waters can still be found on Beula, Cascade and Riddle lakes. Use small leech and small beadhead nymph patterns for wet flies. Use midge and callibaetis patterns for dry fly action here.
Right now terrestrial patterns get you the best action on most streams. With cooling and shorter days the Firehole River will offer better action from such as BWO and cadds activity. Trico spinner falls bring action on all Fall River Basin streams. Brown trout are beginning to forage before spawning runs. So be sure to have streamer patterns in your fly box. As we move through autumn, rely more and more on them to bring action.
Big dry fly attraction here are green drakes on Slough and Soda Butte creeks. There and on other Park streams terrestrial patterns work well. On lakes such as Beula, Cascade, Grebe, and Riddle gulpers are active. On streams hosting brown trout streamer patterns will become increasingly important as we move into fall.
The upcoming months can be the best to try Park waters. The number of tourist-anglers is down, insect pests are decreasing, and more comfortable weather is coming. Terrestrial insects and caddisflies will be active for weeks to come, the fall mayfly emergence (BWOs, mahogany duns, Slough Creek green drakes) will take hold, and streamer fishing will become increasingly productive. Get in touch with us for “where to fish” information, flies, equipment, and strategies for the fall season.
Generally best action is found through presenting terrestrial patterns on streams and presenting patterns for gulpers on still waters. Days are shortening and we are beginning to cool in the high country. These are signals to begin thinking about presenting streamers.
Terrestrials, particularly ant and hopper patterns, are bringing action on almost all streams. Don’t overlook presenting ant patterns on lakes. Carry cinnamon and black patterns of various sizes in order to be ready for which are attracting fish. And remember lakes such as Beula, Cascade and Grebe have great ant flights this time of the season.
No real change here in that terrestrial patterns are the most consistent producers on Park streams. On higher gradient streams like the Gallatin, the middle and canyon reach of the Gibbon, lower Gardner River and Lava Creek add caddis life cycle patterns. For still waters gulpers are active and approachable on smaller waters such as Beula, Cascade, Grebe, Riddle and Wolf lakes. Trty a dry damselfly pattern on these where you see rises.
