Trout Spey has become more popular around Bozeman, MT. Learn how anglers are using two-handed rods to swing flies on the Yellowstone, Lower Madison, and Missouri rivers.
Trout Spey Fly Fishing Bozeman
Trout spey gives anglers another way to approach fly fishing around Bozeman. While two-handed rods are traditionally associated with steelhead and salmon, lighter Trout Spey rods bring many of the same techniques to Montana trout rivers. For anglers curious about Spey fishing but unsure whether it makes sense for the rivers around Bozeman, there are plenty of opportunities to put one to use.
A trout spey rod isn’t necessary; it is something that can breathe new life into the sport for anglers who have been fishing the Bozeman area for a while and want to add a new skill set to their expertise. Swinging is not nearly as popular as single-hand out here, but it is not uncommon to see anglers giving it a try on several of our local rivers.
Choosing a Trout Spey Rod
A 3- or 4-weight trout spey rod will cover most of the fishing around Bozeman. A 3-weight provides a lighter feel and works well for smaller flies and lighter presentations. A 4-weight gives anglers more power when throwing streamers, heavier flies, and sink tips.
For anglers looking for one trout spey rod to fish a variety of Montana rivers, a 4-weight is a good place to start. It’s going to be easier to cast a variety of trout flies.
Bozeman Fly Fishing Guide Trout Spey Recommendations:
Our favorite is the Sage TROUT SPEY HD 4113-4, it is an 11'3" 4-weight that works well for the heavier side of Trout Spey fishing. It has the power to cast Skagit heads, sink tips, and larger trout streamers, making it a good match for rivers like the Yellowstone and Missouri. Anglers planning to spend most of their time swinging streamers will appreciate the additional power of the 4-weight.
For anglers looking for a solid 3-weight, the Orvis Mission Trout Spey Fly Rod 3114 is a bit lighter. It works well with smaller streamers, soft hackles, and lighter tips, and the 3-weight keeps the rod fun when fishing for average-sized Montana trout. This rod makes the most sense for anglers who don't expect to spend most of their time casting heavy tips and larger streamers.
The Winston MICROSPEY AIR 2 - 4113 is an 11'3" 4-weight with enough power for streamers and sink tips; lighter flies and scandi heads are a bigger challenge with this rod. For anglers looking for one 4-weight Trout Spey rod to swing streamers on several Montana rivers, this option from Winston will do it well.
Choosing a Reel
A fully caged reel is a useful addition to a trout spey setup. Spey fishing involves managing a fair amount of thin running line, and a full cage helps prevent that line from slipping between the spool and reel frame.
The reel should also balance the longer rod comfortably. There’s no need to overcomplicate the choice. A reel that balances the rod, has a reliable drag, and keeps the running line contained will do the job.

The Sage TROUT SPEY 3/4/5 was built specifically around light two-handed rods. The full-frame design keeps thin running line from slipping between the spool and frame, while the added weight helps balance longer Trout Spey rods. The 3/4/5 size pairs well with 4-weight Trout Spey rods and has plenty of capacity for a Skagit head, running line, and backing.
Another solid option being the Galvan SWING S2-3/ S4-5 is a reel designed with Spey fishing in mind. Its full-cage frame keeps running line contained, and the additional weight helps balance a longer two-handed rod. The S2-3 makes sense for lighter 3-weight setups, while the S4-5 pairs well with 4-weight Trout Spey rods and anglers fishing heavier lines and tips.
Trout Spey on the Yellowstone River
The Yellowstone River is where some of the advantages of a Trout Spey rod become more apparent. It’s a big river, and there are plenty of places where covering water is part of the fishing.
A Skagit head and a selection of sink tips make it possible to adjust without changing the entire setup. For swinging the Yellowstone, anglers should bring at least one 10' T-11, 7.5' float 2.5' sink, and full float tip for fishing shallow sections through Livingston and down towards Big Timber.
For anglers exploring the Yellowstone with a Trout Spey rod, the water between Livingston and Big Timber is a good place to start. The combination of wide channels, consistent current, and long swing runs gives anglers room to work tons of water.
Trout Spey on the Lower Madison River
The Lower Madison River is a good place for anglers to get comfortable with Trout Spey. Much of the river lends itself naturally to swinging flies, with long sections of water where anglers can make a cast, let the fly work across the current, take a few steps, and repeat the process.
A Skagit setup is particularly useful on the Lower Madison because anglers can fish streamers and easily change tips to control depth. A lighter tip or even no tip is going to cover most sections from Warm Springs to Blacksford. With how easy the river is to traverse, anglers can easily set themselves up to swing holes from most distances.
Anglers who already fish streamers on the Lower Madison with a single-hand rod don’t need to completely rethink their fly selection. Many of the same streamers can be swung with a Trout Spey rod. What changes is the depth they will be working.
Trout Spey on the Missouri River
The Missouri River below Holter Dam has some of the best swing water in the state. Fall and winter are particularly good times to bring a two-handed rod, and Craig itself has become a hotspot for catching big fish on the swing.
The Missouri also gives anglers more options than just swinging a streamer. Small leeches and streamers can be fished on sinking tips, while soft hackles and smaller wet flies can be swung higher in the water column. The variety of hatches makes the Missouri a fantastic river for swinging, as it gives anglers opportunities to try out different tips without needing to be incredibly technical.
The way the Missouri River is structured creates plenty of good water for swinging flies. On rivers like the Gallatin and Madison, anglers often have to search for sections with the right current and enough room to make a Spey cast. The Missouri’s size depth provide tons of great swing water.
