Fishing ranges from good on the Teton River in the basin to slow in the lower Blackfoot River. Afternoon BWO emergences on the Teton River are making for great action, and if the predicted stormy weather happens, this weekend and early next week could be a great time to enjoy this hatch. It might also improve fishing on the lower river where low water has slowed action a bit. Flow out of Blackfoot River Reservoir is down to 67 cfs meaning fish are concentrated in deeper water in the lower river. This combined with the bright skies makes fish skittish. Best place to fish is deeper waters especially where these are bordered by weed beds (overhead cover) which are beginning to break up. Hoppers are plentiful along banks, but a killing frost is not far off in the future.
