Best Fly Fishing in Montana

Fly Fishing in ‘The Big Sky Country’ Montana

Best Fly Fishing in Montana

Hebgen Lake

Hebgen is one of Montana’s dependable trout fisheries. In the summer and winter, you will spot huge numbers of large brown and rainbow trout in these waters because of the conducive habitat and excellent forage.

They make trips to and from the Madison River to spawn. Once they reach Hebgen Lake, they give serious anglers greater chances on calm days to sight fish cruising. Their primary food are tricos and mayflies. Access to where the fish are is via a float tube or a boat.

We can’t name them all but there are very many spots where you can launch your tube on this lake. However, highway 287 runs along the lake on the northern side, making it easy to gain access. Additionally, several other roads provide access to the south side of the lake, where numerous campgrounds are also found.

There isn’t a very good shoreline for waders and those who choose to walk on while fishing. Fervent anglers can remain on the Grayling or Madison arms of the Hebgen. The lake sometimes experiences heavy boat traffic so note this as you select your spots.

Season: Winter and Summer
Main Species: Rainbow and Brown trout
Fly Pattern: Mid emergers, callibaetis, duns, spinners, and tricos.
Nearest Towns: Hebgen Lake Estates
Nearest Tackle Shop: River Edge, The Tackle Shop
Must Carry Gear: Leaders-these chaps get spooky.

Missouri River

Missouri is where most of the trout streams in Montana drain into. Lewis and Clark were among the first people to explore this river and boasts so much in history. The explorers were in search of a water route that leads to the pacific. Despite not being successful, their major discovery was Montana’s best trout stream.

Anglers frequent this place since it homes some of the largest brown and rainbow trout. If you are a dry fly expert, this is a point to sight fish. As part of the fourth longest river system in the world as it joins the Mississippi the Missouri was a building block for the wild west with fur trading steam boats and cargo moving up and down the river.

It was home to many indigenous people and saw many wars as the middle Americas were forged out. Now the Missouri host some of the best trout fishing in the North Americas.

Missouri’s formation is at the Three Forks where Gallatin, Madison, and Jefferson rivers meet. Missouri has great fly fishing spots. However, a hot spot we can recommend is the Holter Campground. It is below the dam and has a boat ramp where you can launch your boat. You can also enjoy night mousing for trout here.

There is so much to brag about it since it is one of the longest free-flowing rivers in the United States. You can do more dry fly fishing here.

Commencing from the Yellowstone National Park passing through the Paradise Valley and heading further, access is superb. The river is extremely large and float fishing will be an ideal mode. You can try your chances in wading and walking since the currents are fair.

Madison River

Right at the convergence of the Gibbon and Firehole rivers in Yellowstone National Park is where the Madison River begins. It is a 183-mile riffle. Its uppers can be confused for a humongous spring creek. The river enters Montana and feeds the Hebgen Lake.

There is a tailwater below the Hebgen and though short, it is an excellent fishing point. Quake Lake is also great to hook on a few buddies.

The primary access is the $3 Bridge for waders and is always crowded because of the mountain whitefish, brown, and rainbow trout spend the most time here. The summer attracts mayfly spinners and evening caddis.

From the bridge downstream, the river is easily accessible and float anglers will be successful here. The lower section begins from the Lake Ennis down through the Beartrap Canyon. Access in the lowers is tricky though if lucky, the fishing experience here with larger trout and crawfish.

Yellowstone National Park

It is only a section of this National Park in Montana. This small part can engage an angler in a lifetime without adventuring other places. Despite the striking geothermal features and beautiful wildlife, there are lots of fly fishing opportunities here.

You can hook mountain whitefish, grayling, cutthroat, lake, brown, brook, and rainbow trout. You can sometimes visit the Madison River and fish the fall run.

Late summer is when the lake trout head up the park. As the fall peaks, so does the run. One of the best times is from mid to late in October when the weather is completely off. You should be fully armed with winter gear.

The northeastern part of the park is a great deal. Get into the Lamar valley from Cooke City and fish the Lamar waters, Slough or Soda Butte Creek. You will land lots of Yellowstone cutthroat trout if you present you dry flies well. Have a feel of terrestrial fishing when the summer peaks and ends.

Gallatin River

Gallatin River has its headwaters in Yellowstone Park and is an excellent trout river to fish. As you head further downstream, that is where the best fishing experience is. This section is the anglers’ favorite. NOTE: Float fishing is forbidden in most parts of this river.

Waders will have incomparable moments here. You can float fish below the river’s junction with Gallatin’s East Fork. The only limitation is access to the waters. So, float fishing is the only option in the lower section.

Ruby River

Unlike most blue ribbon rivers with three sections, this one has two. The upper hails from the Natural Forest lands and is a hot spot for small to medium size cutthroat and rainbow trout. You can occasionally catch grayling too.

After the forest, access is limited because of private properties. Montana laws only allow you to access waters that are below the given high watermark. Remaining in the stream and not accessing corporate property will save you lots of trouble.

Below the Ruby Reservoir holds a brown trout fishery that is worth exploring. There are no crowds here and the fish are a little cooperative. If you are looking for a hopper fishing chance, Ruby’s lowers is it.

Summer through fall is when brownies battle the hoppers. Stay away from the upper banks since they are very bushy and navigation is almost impossible.

Other Hotspots that you can Adventure

Rock Creek is a wader’s choice. It is sizeable and has plenty of access and you should expect more rainbow and cutthroat here because salmon fly, yellow sallies, caddis, and stoneflies love to hatch here.

Jumbo brown trout will never fail in the Beverhead waters. Most anglers fish in its uppers and there are rules on float fishing. You can carry your light tippets and nymphs to hit a few in this river. Streamers might be a gamble.

Spring Creeks of Paradise Valley is a private spot and toward the higher end price-wise. Pale morning duns and other mayflies hatch here in abundance luring fish to the water surface. Large brown and rainbow trout are the chaps here though landing them can be tricky. Carry your fine tippets, long leaders and light rods to this creeks.

Anglers will appreciate the shallow waters of the Ennis Lake. In calm weather, drifting a boat with tricos or callibaetis will see you hooking trout. Guides advise fly fishing this lake during morning hours.

The Clark Fork River was on its way to total destruction as a result of mining waste runoffs. There have been ongoing Superfund cleanup programs to rescue this gem. The upper section harbors brown trout and access can be a problem. As you near Missoula, this is the best place to fish.

People hardly come to Glacier National Park to fish but once here you can exploit the many rivers and streams. You can land native cutthroat which is what is mostly fished. Bull trout too are in plenty.

Jefferson River is an option for tranquil spots if you are hoping to fish far from crowds. It is hardly fished and needs patience because of the low population of fish. You can streamer fish in its upper section for brown trout.

Cliff and Wade Lakes are closer to the Madison River and harbor huge trout and weigh up to 30 pounds. Most anglers do subsurface fishing but sight fishing for cruising trout is also possible. You can use a sinking line with crawfish or leech patterns if you want to fish where the large trout are. Hire a canoe or float tube for more success.

Tips for Fly Fishing in the Big Sky Country

Ensure to carry various sets of tippets and leaders. If you are set to dry fly fish, carry a good number of long leaders for fishing on several rivers and lakes. They should be about 12 to 15ft 5X tippet size. Once in a while, you can choose a heavier one depending on your choice of fly and the season.

Some spots in the wilderness are graced with grizzly bears. It will be rather cautious of you to carry effective bear spray than ruin what was to be a fantastic experience in one of Montana’s wildernesses.

Stock your fly boxes with many flies that match a variety of hatches. Morning duns will work well in most streams and rivers, caddis, stoneflies, Salmonflies, and yellow sallies will do excellently on many streams and rivers. Lake fishing will need a bunch of tricos, leeches, crawfish, and callibaetis.

In soft winds on rivers like Gallatin, having a longer rod of about 10 feet and 3 or 4 weight will be ideal to reach potential spots. This also applies to areas like Rock Creek.

Sinking lines are good options for fishing in lakes with deeper waters. 4 weights will be superb for catching gulpers. These chaps can be spooky and lighter presentations and landings will yield. In spring creeks, use the same paired with a 3 or 4 weight fly rod when winds are soft. These lines will favor anglers looking to throw streamers to catch larger trout. However, having this line on a seven weight rod is among the surest things to do.

Generally, if you are a light packer, arm yourself with a 9ft 5wt fast action rod and a weight-forward floating line. The combo favors most applications. However, if you’d wish to add something to cut through the winds on such days or hit big waters, tag along a 6wt.
