Fishing on the Firehole river is picking up with BWOs, tricos, & caddis attracting fish. But a cold snap in needed to really get things going. Elsewhere good terrestrial insects are numerous as there has been no blanket killing frost. This begins the time of year when brown and brook trout are on the move to spawning areas. Streamers are the way to encounter them, especially the big browns. These are moving into the Madison River above Hebgen Lake, but waters are warm enough that good action is in the future. It’s much the same with the Lewis River system; A touch of cold weather would bring on best action from migrating browns. C’mon cold snap!
