The Jefferson River between Bozeman and Butte has dropped substantially and is now a good fishable option. Mornings are defintely better than afternoons as water temps get warm later in the day. The Jefferson isn't a great mid summer fishery once water temps warm too much. This is a low fish count river compared to others in the region so it isn't the place to put numbers in the boat but it is an interesting alternative for some variety.
The Month Ahead:
The Jefferson River is never a high numbers game due to lower trout counts but it is a nice location to get away and see few other anglers.
Long Term Fishing Forecast:
The Jefferson will be tough once flows drop to summer base levels as it tends to get pretty warm for good fishing in late July and August.
