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.
