Because the Missouri River near Wolf Creek and Craig and north of Helena is a tailwater, it is a very good option for winter fly fishing compared to some of the other rivers in the state. The dam release river often runs ice free--at least for the first dozen or so miles downstream of the dam. If you do venture to the Mo to fish, consider walking-and-wading versus floating. It is also a good idea to bring a buddy or tell someone where you are going because a slip and fall and getting your waders full of wader can be dangerous as it doesn't take long for hypothermia to set in.
Because the flow on the Missouri River is regulated and consistent coming from Holter Dam, anglers wanting to get out and find some fish in winter are best suited to head to the Missouri River. Compared to the busy summer season, winter on the Missouri River sees less anglers, but it also see a lot less feeding duration of the river's abundant trout population. During winter on the Missouri River, hatches are minimal and will mostly only consist of midges. For the next several months the best way to get into good numbers on the Missouri River will be to fish tandem nymph rigs using midge, beadhead PTs, or your favorite scud or sowbug patterns. A firebead or hot bead SJ worm will also be successful. Swingers and streamer anglers can also find some success on the Missouri right now, but it will be slow compared to just a few weeks ago.
Because the weather this year can be cold, it is important to plan any float trip with comfort and safety in mind. Watch the wind as well, because even if the air temp is in the 30s or 40s but if the wind is forecast for more than 10 to 15 mph it can be quite cold in a boat on the water. With streamflows hovering around 3,200 CFS do it yourself wading anglers will find plenty of accessible water and options for good fishing.

The Month Ahead:
Expect things on the Missouri River to remain the same for awhile as we get deeper into winter. The fish are going to stay in the slower and deeper runs as the most available food is located there.
The Mo should produce all winter. Later winter will see some decent midge hatches and a chance for dry fly fishing. Wind can be an issue in the winter but the trout should still be feeding in the afternoon hours on a daily basis.
Long Term Fishing Forecast:
The Missouri below the dam at Wolf Creek is a good winter fishery. Nymphing the slower seams will be the staple until the stronger midge hatches arrive in the later winter and early spring.
