Big activity now is brown trout migration in the Madison, Gibbon, and Lewis rivers and Duck Creek. Later in the month brown trout runs on the Snake and Gardner rivers will kick in. Streamers on sink tip lines are the name of the game on all of these with low light conditions offering the best times to be on these waters. Lewis Lake offers good trolling and shoreline casting for browns near the outlet and through the channel at the north end inlet. Browns are now piling up in the channel below Shoshone Lake, but so are anglers. Some of the Park’s best fishing for browns can be had here if you are the first one of the day to venture in. If you prefer dry fly fishing, the Firehole River is fishing very well with BWOs and caddis leading the way. Jack Frost has pretty much nipped most hopper fishing at the bud, but a few can be found around Fall River Basin streams. Speaking of Fall River Basin, Beula Lake fishes well on bluebird days this time of year. Use small bead head nymphs, Midge pupa patterns under indicators or small leech patterns.
