5 Best Hatches on the Bitterroot

by MAngler

The Bitterroot River runs south to north through the Bitterroot valley, and is a very wader friendly river. Fishes big, wades small, and the Bitterroot River hatches are the most diverse in the Missoula area. Here is a list of some of our favorite hatches on the Bitterroot.

Trico

Trico Spinner Fly Fishing

From a hatch matcher’s standpoint, the Trico hatch is the most frustrating, tricky, amazing and challenging of the Bitterroot River Hatches. Coming in at an 18 or 20, the small size starts the trico challenge. Add that the trico is the only local mayfly with distinctive male and female coloration, and toss on the spinner fall that occurs during the hatch, and you have a serious puzzle for the angler to solve.

The Tricos are a blanket hatch, coming off in huge numbers starting mornings in mid-August and continuing through mid-October, depending on weather. The spinner clouds that form above the river prior to the hatch are identifiable by the figure 8 pattern they fly in. The cloud will form about 15 feet above the water, and slowly drop to the surface. The spinners are also identifiable as male and female, so once they fall and the hatch starts, you have male and female spinners on the water, as well as male and female adults, cripples and emergers. The Trico hatch can really stretch the width of an anglers fly box!

Contrary to most mayfly hatches, the tricos hatch best in full sun, which makes the trout a bit skittish when up feeding on this hatch. Which the trout kind of have to do, as the Trico is the only reliable source of food at this time. The fish will line up in the slow glides and pools and take these insects for as long as they are present on the water. While the Tricos will appear above Bell Crossing, the best Missoula Trico fishing is found in the wider, slower sections of the lower Bitterroot River.

Make sure you’re ready for this hatch when you hit the water. Ron’s Trico Spinner has been our top producer for this hatch for years, but you’ll need more flies than that! A Female Comparadun or Trico Sprout will also turn heads when the hatch is on. The Sunken Spinner is a great fly when the fish are focused just under the surface, dropped off a Parachute Trico or even a smaller Royal Wulff- also a sneaky good fly when the tricos are on.

Make sure you’re ready with a well-balanced leader tapered down to 5 or 5.5X. Your casting needs to be somewhat long and quite accurate. The tricos are so small, and there are so many on the water. The trout don’t move very far to the left or right to take your fly. It needs to be in the feeding lane, floating correctly, and matching the phase of insect that particular fish is feeding on. Spinner, adult, cripple or emerger in both male and female. It can be the most frustrating hatch to work when you’re not on, but when you find the fly and start getting the drift, the satisfaction of having solved the riddle is one of the best feelings you can have when heading out to match wits with the wily trout!

Skwala

Bitterroot Skwala Hatch
Bitterroot Skwala

The Bitterroot River is known across Montana and the west as having the best skwala stonefly hatch in the area. This early spring stonefly begins hatching in the 2nd or 3rd  week of March and will continue through run-off. The females are olive and run from size 8 early in the hatch to a size 12 near the end. The males are dark and smaller, and rarely find their way to the water. As with all stoneflies, the Skwalas emerge by crawling out along the sides of the river, so the trout will follow the nymphs to the shore. Use a Double Bead Peacock Stone or an Pats RubberLegs to match the nymphs early in the hatch.

The Skwalas will come off along the entire length of the Bitterroot River, as well as the East Fork and West Fork of the Bitterroot. As the first hatch of the year, there’s a lot of pent up fly fishing in Missoula, and the Bitterroot can see its fair share of anglers at this time. Pick your days to fish the Skwalas! They will hatch in the worst conditions- snow, rain, clouds and cold weather. Conditions like that tend to turn away the faint of heart. Dress warmly and go knock ‘em silly!

If you’re running a dropper like a Tungsten Hare’s Ear Jig for the Western March Brown nymph, use an Morning Wood Skwala or Olive Water Walker. These big foamies will float your nymph and work well early in the season. As the hatch progresses, and the fish get wise, switch up to the Little Olive Stone or Rogue Stone Skwala. They float lower in the water, and look more realistic to the fish.

Skwalas will hatch on gray days, and with their dark coloration can be very difficult to see on the water. You must look carefully for them as they go floating by. The random rise will also alert you to their presence on the river. Work the good looking water, and be ready for some slow times, especially in the colder morning. The crafty Skwala angler will often wait for the afternoon to start fishing, allowing the temperatures to warm and get the adults flying. It’s a great way to start the season- big bugs and lots of action!

Western March Browns

March Brown Hatch Montana

The Western March Browns will start hatching in the last week of March, and will go through run-off. The WMB is well imitated by the Purple Haze, Parachute Adams or the Parachute Hare’s Ear. While the WMB’s come off consistently during the Spring, they are rarely a blanket hatch. Unlike the Trico, it doesn’t take a lot of flies to effectively fish the WMB’s. Sure, a cripple or emerger is useful, but certainly not required.

The WMB’s really like clouds, and that can be a bit problematic early in the hatch. It takes a bit of warmer weather to get the flies moving at the beginning, and clouds aren’t always the best at allowing warmth. But once the WMB’s get established by the first week in April, they consistently come off in the afternoons along the length of the Bitterroot River. They’re found in size 12-14, but concentrate mostly on the size 14. When you go subsurface with a WMB nymph, have a few Umpqua Ptail Jig or PT Hot Spots to get deep quickly and stay in the zone. This is one of the favorite bitterroot hatches for local and traveling anglers.

Golden Stones

Golden Stone Hatching On The Blackfoot River

The Golden Stones could just have easily been the third hatch on this list of best Bitterroot river hatches. They are a very prolific hatch on the Bitterroot River, including the East Fork and West Fork. Unlike the Skwala, which is a single species, the Golden Stone hatch is comprised of multiple species that range in size from 6- 12, with the most falling in the 8-10 zone. Expand that slightly, and you can include the Yellow Sallies, which are smaller Golden Stones in size 14-16. In the last week of June through July, the Goldens offer a smorgasbord of insects for the trout to gorge on.

The upper stretches of the Bitterroot are faster and choppier, so a high floating Golden like a Plan B Golden or an El Camino Golden are strong producers. In the lower sections, where the water may be a little calmer, the PK Golden or Rastaman Golden will perform very well. Make sure to have some Tan/Brown Pats RubberLegs with you when the surface action isn’t where you want it to be. Be ready for bigger water during the Golden hatch, especially at the start of the hatch, and work the edges of the river. As the water drops during July, the fish will move from shore to their familiar summer feeding stations.

Mahoganies

Mahogany Dun Hatch

The majestic Mahogany is found on the Bitterroot River from the first September rains through the first real snowfall. They hatch in the heat of the day, which on some October afternoons can be 45 degrees! They’re a sizable insect, about a 12-14, and are easily seen on the water. The Mahoganies aren’t a blanket hatch, and if you get a reasonable imitation over a fish, they will usually take.

We like the Tilt Wing Mahogany at this time of year, as well as the Pheasant Tail Dry. If you want to get fancy, a Hi Viz Rusty Spinner in a 14 can be money, as can a Mahogany Sprout. When you go subsurface, an Solitude Pheasant Tail Jig or Quill Perdigon Jig will be very effective during this hatch. While it hatches along the length of the river, the best hatches are found below Bell Crossing.

Honorable Mention For Bitterroot River Hatches

Honorable mention on the best Bitterroot River hatches goes to the Hecuba hatch. While not a prolific hatch by any stretch of the imagination, the Bitterroot trout love this late summer/fall hatch and will take them whenever they’re on the water. If you find yourself on the water in Fall with little happening, tie on a Brindle Chute in a size 12 and start prospecting. You’ll be pleasantly surprised at the results!

5 Best Hatches on the Blackfoot River

by MAngler

The Big Blackfoot River is where A River Runs Through It takes place. Home of the Big Fish, and it was taken on a big fly! The Blackfoot River hatches are prolific and is a perfect habitat for stoneflies and Caddis. We’re going to start big!

Here is a list of our favorite Blackfoot River Hatches

Golden Stone

Golden Stone Hatching On The Blackfoot River

The Golden Stones, comprised of many stonefly species all imitated by the same flies, are the premiere hatch on the Blackfoot River. Not by size, but consistency. The Blackfoot River is the highest altitude and northernmost river in the Missoula area. It’s often the last river to heat up after run-off and usually the first to shut down in the fall. While the Salmon Flies can be epic on the Blackfoot, the Golden Stones are a guarantee year in and year out.

The Goldens begin to hatch in the last week of June, and as soon as they establish themselves, Missoula’s most experienced fly fishing guides tie on a Golden. They’re smaller, running from size 6-12, which makes them more accurate in the high water found at the beginning of the hatch. The high gradient Blackfoot River will push fish up to the banks in high water, and often the difference between success and rejection is 6 inches. The smaller fly goes where it’s aimed, and moves fish in the water they’re comfortable in.

It’s easy to talk all day about the dry fly fishing provided by the Blackfoot River Goldens, but anglers do themselves a serious disservice by ignoring the subsurface Golden activity. Take one look at the Blackfoot River, crashing through boulders and cascading against bluffs and rock walls, and the water just screams nymph. You know big trout are hanging behind boulders and rocks, and those trout haven’t been to the surface in 4 years. Drop a Brown/Black Pats RubberLegs paired with a Peacock Double Bead Stone. Don’t be afraid to run the point fly 6 feet deep and the dropper 8 feet deep! It’s a big, roiling river, and the fish get deep and stay there. You’re going to get a lot more done if you get to the fish on their level, not make them come to yours!

Which isn’t saying the dry fly fishing is no good! The Golden Stones on the Blackfoot River can provide the best dry fly fishing in Missoula for the season. It’s that good. Early in the hatch, go with big and foamie, like Clook’s Floater In The Pool or an El Camino Golden. These will also hold up a dropper if that’s needed. As the season progresses, and the fish start to move away from the banks into summer water, think a bit smaller and lower floating. A Demoe’s Mill Creek Golden or Morningwood Golden are top producers when the fish start to slip away from the banks. If the dry fly action slows for some reason, throw on the Chubby Chernobyl Golden and run a dropper. The Chubby may be the best indicator fly in your arsenal, with its high floating, easy to see wing and foam body.

Word to the wise for the Goldens. The Blackfoot is a tricky river to row in early to mid-July. All the teeth are sticking up, and there’s a lot of push from the high flow. Be vigilant on the sticks- no one wants a yardsale!

Salmon Fly

Salmon Fly Hatch In Montana

We know there’s a lot of blowback here. Why isn’t the Salmon Fly the number one of the Blackfoot River Hatches? Because while its big, and when it’s on every fish in the river is up and eating, it can be inconsistent in a cold spring/Early Summer. But when it finally comes on, it is ON! The Salmon Fly will start on the lower sections first, but it moves much more rapidly along the length of the river. The Salmon Fly can establish from Weigh Station to Ovando in about a week. We like to start the season with the biggest, highest floating Salmon Flies we can find. Super Gee, Damien’s SUV Salmon Fly and other gi-normous foamies! Don’t worry about them floating too high, the big roiling river will keep them in the film. If you can do it, these flies will take a dropper as well, doubling your chances of a hook up on the bank.

Don’t be afraid to run a 6 or 7 weight rod during the salmon fly hatch on the Blackfoot River. Running 1-2X tippet, you have the ability to apply the wood to the fish once they’re hooked. And you’re going to need it! Get a slab-side brownie sideways in that current, and you’ll know why Brad Pitt decided it was easier to float with the fish than fight the current. Be ready with a big stick for the Salmon Flies.

The big stick is also useful at the end of the Salmon Fly hatch, as the Goldens are starting to make their presence known. How often do you get to run a size 6 dry fly on point with a size 10 dropper? The Blackfoot River hatches offers the perfect venue for the big double dry rig. Can’t decide what to throw? Let the trout decide. The Blackfoot River is also a great river for a “tweener” fly. That’s a fly like a size 6 Rogue Golden or Morningwood Special that COULD be a darker Salmon Fly, or it could be a Golden. Let those flies do double duty. You don’t care why they took it, just that they did!

Go back and refer to the nymphing paragraph in the Goldens. Same thing for Salmon Flies, just substitute a Black Pat’s Rubberlegs or a Black Double Bead Stone. ‘Nuff said about subsurface.

Spruce Moth

Spruce Moth Hatch

While not a true hatch, when the Spruce Moths are on, the Blackfoot River can look like it’s raining on a clear August day! The Blackfoot runs through a corridor that is surrounded by pine trees, especially along the recreational corridor. While the bird watchers and forestry people are watching the tops of the trees whither and go brown, the angler is firmly focused on the adult Spruce Moths returning to the water. Why they return to the water is up in the air, but they come down like a bee to honey, and the trout take advantage of this unexpected August food bonus.

Our best Spruce Moth pattern is Ron Beck’s MAngler Moth. It’s spun deer hair body perfectly mimics the moth’s variegated body coloration, and it floats like a cork. If you’re looking to run a different bug from the back of the boat, try a Spruce Almighty or size 10 Tan Caddis. Both these flies will move fish when the Spruce Moths are out. Don’t worry about a Spruce Moth larva dropper. While we’re sure a few find their way to the river, the immature Spruce Moth is not really a thing, making the Spruce Moth a Dry Or Die favorite!

Hoppers

Grasshopper Hatch

Again, this isn’t truly a hatch, but the hoppers come right on the heels of the salmon Flies and Golden Stones. The trout are looking up for big flies- why would they stop when the hoppers come out to play! The Big Blackfoot is a wide river as it heads into Missoula, and hoppers aren’t very good flyers. Many find their way to the surface, where the trout are looking for the unlikely meal. The natural forestation that surrounds so much of the Blackfoot is great hopper habitat, and the hoppers are in play up here from late July until the end of the season.

We like to start with a natural colored hopper early in the hatch, like a Morrish Tan Hopper or Parachute Hopper. Though many of Missoula’s most experienced guides will use a Gold Morrish Hopper or a Peach Fat Frank. They do this to jar the memory of the trout back to Golden Stones and Salmon Flies, giving the trout one more reason to come to the surface for food. As the season progresses, get some big hoppers and make use of those as well. Size 6-8 can really produce along the recreational corridor. A great dropper off the hopper is a Solitude Pheasant Tail Jig or FireStarter. Both have proven themselves in the hot summer days on the Blackfoot River.

October Caddis

October Caddis Hatch

The October Caddis can start as early as mid-September on the Blackfoot River, so be ready. They’re tough to miss when they’re on the water, and the trout will look for them from the moment they first hatch. Not sure if the October caddis are out yet? Drop an October Bird Of Prey off the back of a big hopper, and let the trout tell you if the October Caddis are out and about.

Our favorite October Caddis dry on the Blackfoot is the simple Orange Elk Hair Caddis or Orange Stimulator. Both are high floating flies- very useful in the fast, roily water found along the Blackfoot River. Both will float a dropper, to a point, and are very effective when the October caddis are flying. If you want to throw a change-up to the trout, run a Brindle Chute. The orange body is a perfect copy of the October Caddis coloration,  and the parachute post is easily seen.

Honorable Mention

We’re stretching the honorable mention “hatch” on the Blackfoot River, and going with streamers. While not technically one of the Blackfoot River hatches, streamer fishing is an important tactic for this river. The nature of the Blackfoot River, with deep pockets and steep banks, make it the perfect river to throw streamers at any time. The old adage of big fish eat little fish is never wrong on the Blackfoot, where the turbulent water will muffle the biggest streamers entrance even in the lowest water conditions. If you’ve decided that for today’s angling, size matters, then take a fistful of streamers to the Blackfoot River. Go deep or go home!

5 Best Hatches on Rock Creek

by MAngler

Rock Creek is the quintessential western river, and Missoula’s only Blue Ribbon trout stream. Many locals consider Rock Creek to be their home waters, and live for Rock Creek Hatches. If you could design a river for stoneflies, Rock Creek would be the model. Rock Creek’s high gradient creates fast, highly oxygenated water and a large cobbled bottom that is absolutely perfect stonefly habitat. Here is a list of our favorite Rock Creek Hatches.

Salmon Fly

Salmon Fly Hatch In Montana

Rock Creek is known the world over for its Salmon Fly hatch. Work in the shop mid-June through early July and you’ll hear 4-5 different languages spoken, all with one common denominator- Salmon Fly. That doesn’t need translation. Whether on foot or by boat, the Salmon Fly hatch on Rock Creek is a clarion call to anglers- big bugs here.

The start of the Salmon Fly hatch can be hampered by high water. Run-off traditionally ends just as the Salmon Flies are heating up. Rock Creek’s gradient means little to no silt, which allows Rock Creek to clear long before other local rivers will. Clear or not, the Salmon Flies will hatch and the trout will find them. Also, clear or not, Rock Creek is a tricky river to wade and row during the Salmon Fly hatch. Anglers can cover 25-30 miles in a day by boat- the river is moving that fast. Care needs to be taken in boat or on foot. While on safety, if you’re wading and see a Moose, go find somewhere else to fish. Get between a female moose and her calf and you have real problems.

Traditionally, the Salmon Flies begin hatching at the mouth of Rock Creek, and move 1-2 miles upstream each day on average. Many fishing reports reference “where” the hatch is on Rock Creek- it’s saying where the hatch is densest as it moves upriver. The density of the Salmon Fly hatch is truly magnificent. Find yourself in the thick of the hatch, and you can have Salmon Flies crawling all over you, the boat and every tree on shore. With every fish in the river up and looking for them.

Early in the season, we favor the large, foam Salmon Flies like Damien’s SUV or El Camino Grillo for their ability to float in high water. As the river drops, we go a bit smaller to a Goulds Half Down or a Morningwood Special. A Double Bead Black or Peacock Stonefly Nymph will work well subsurface.

Female Salmon Flies will live for 2-3 weeks in the trees, returning daily to lay new eggs. Over this time, they shrink in size and darken in color. As the hatch moves upstream, crafty anglers will take a smaller, darker pattern like a Bullethead Salmon Fly or Rogue Salmon Fly and go down low. While the crazy hatch (and crazy hatch chasers) might be at Mile 30, the adults are still there laying their eggs at Mile 6, and the trout are still eating them.

Fair warning. Rock Creek is Missoula’s most easily accessed river, with Rock Creek Road paralleling the river for 52 miles. It’s not a secret that the best Salmon Fly hatch in the world is here. If you’re looking to fish in solitude, not another angler within miles, Rock Creek during Salmon Flies may not be for you. Rock Creek is justifiably famous for this amazing hatch, but it draws a crowd. Be ready for that experience.

Golden Stones

Golden Stone Hatching On The Blackfoot River

The Golden Stones follow directly on the heels of the Salmon Fly on Rock Creek, and for many anglers provide more consistent fishing along the length of the river. The Salmon Fly can provide you with frenzied feeding, while the Golden will be consistent throughout the day. Unlike the single species Salmon Fly (Pteranarcys Californica) the Golden Stones are made up of many different but related species of stoneflies, which is why the Golden can vary in size from a 6 to a 12, with most in the 8-10 range. Be ready with multiple sizes and shapes to meet the changing hatch along Rock Creek. The size difference is why the Golden hatch is more consistent- more difficult for the fish to gorge on smaller flies and stop feeding.

The Goldens are coming off when the water is up, so a high floating fly is most effective at the start of the hatch. The Demoes Golden and the Morningwood Golden are both good foam flies that will absorb the pounding of Rock Creek. Because the Goldens will go almost through July, low floaters will work better near the end of the hatch. A Plan B Golden or Halfdown Golden are strong producers near the end of the hatch.

Western March Browns

March Brown Hatch Montana

To be honest, we flipped a coin between the WMB’s and the Skwala Stone. Both appear in the Spring, starting in late March and moving through run-off. Rock Creek hatches tends to be a bit behind in the Spring hatches because it’s in such a steep, narrow valley. Takes a few more warmer days to get the water temps to where the WMB’s will hatch. When they do, they come alive along the length of the river.

Don’t ask an angler where his favorite Western March Brown water is, because they’re not going to tell you! Rock Creek moves quickly, and there aren’t many places for a trout to set up for a mayfly hatch. It’s not the quick dart to the surface for big food like a stonefly. Look for the WMB’s along the edges of the river, and be ready with some strong mending to get the drift. The good news is the trout up and eating don’t tend to be fussy, and a well presented fly in the correct size and color is effective most of the time.

We favor the Hare’s Ear Dry or Parachute Adams when the Western March Browns are on the water. If you feel you need a bit more, the Last Chance Cripple will do the trick for the fussiest fish. If you see a few WMB’s flying but don’t see any active risers, work the fly over the good water. For some reason, prospecting with a WMB is effective, so take advantage of that.

Skwala Stonefly

Bitterroot Skwala Hatch

Rock Creek is a stonefly factory, and the Skwala is no exception. Depending on the weather, the Skwalas may start as early as mid March, but will be in full swing by the end of the month. Rock Creek is typically low and clear when the Skwalas hatch, so no 1X tippet on a short leader here. You’ll need to get out a bit, and work with the lightest tippet you can when using a Skwala.

The Skwalas are found along the length of the river, and in the Spring are not fished as heavily as other local waters, specifically the Bitterroot River. Just as Rock Creek is famous for the Salmon Fly, the Bitterroot River is famous for the Skwalas. A bit of contrarian fishing can reap big benefits with Skwalas on Rock Creek. The hatch isn’t as dense as the Bitterroot, but neither are the fishermen, so that can be a good trade off. It’s not that Rock Creek doesn’t get a strong hatch, it’s just not the strongest. Use that to your advantage.

We love the Morningwood Skwala on Rock Creek, as well as the Rogue Stone Skwala. These two flies are strong floaters, and will easily support a WMB nymph, like a Tungsten Jig Hare’s Ear, so you can double your chances at this time. If the day calls for a low floater, go with the Rastaman Skwala or the Half Down Skwala. Both are very effective in slower water as well as days when the fish are a bit sluggish.

October Caddis

October Caddis Hatch

Rock Creek is home to many caddis species, and late in the season the big boy comes out to play. The October Caddis is Missoula’s largest caddis species, and when they’re on the water, the trout are eating them. It’s rare to find enough October Caddis on the water to where the fish will set up and consistently rise to them, but that doesn’t matter!

If you see an October Caddis on the water, tie one on the end of your line and start prospecting. If there’s one, there’s more, and the trout know it. Work the likely water, and don’t be afraid to put 3-4 casts over a likely spot. Sometimes a few extra casts alert the trout to the hatch, and you’ll take a trout that thinks it’s missing something.

Our two favorite flies for this hatch are the Orange Elk Hair Caddis and the Orange Stimulator. Both are strong surface performers, while the Stimulator has the added bonus of floating high enough to use a dropper. The Bird Of Prey is a great October Caddis pupa, and you can also run an Umpqua Pheasant Tail Tungsten Jig to imitate the Mahogany nymphs that are also present in the Fall. Be ready for a explosive rises and hard subsurface takes to the October Caddis.

Honorable Mentions

Honorable mention on Rock Creek hatches goes to the Spruce Moth. While not technically a hatch, and not always consistent, if Missoula has a big Spruce Moth year, Rock Creek will go crazy. The Spruce Moths appear in early August, when little food is available in-stream. When they come to the water, every trout in the river is looking for that bonus food. The Spruce Moth isn’t something to set your watch to, which is why it only gets honorable mention.

Matching The Hatch And Identifying Insects

by MAngler

It’s a complicated world out there, the first time you dive in. Pteranarcys Californicus, Ephemerella Guttulata. It’s enough to send you back to the Royal Wulff and a Prince nymph. Which makes sense, because the only good description we’ve ever heard about why the Prince works, is it’s the nymphal form of the Royal Wulff! That’s a fly joke. You’ll get it before the end of this article, promise!

Insect identification is much easier than you think. Look at it this way. A guy walks down the street with a Chihuahua on a leash, and you think, nice dog. Right after comes a woman walking a Great Dane, and you think, nice dog. Now what on earth made you think those two animals were related to each other? Well, it starts with familiarity. 4 legs. Elongated snout, fur, canine teeth. Despite the size and color disparity, you know they’re both dogs. Because you’ve grown up around dogs, seen them all your life. it’s familiar.

As you spend time on the water, the sight of the insects will also become familiar. They’re smaller than a Great Dane, and no one will have them on a string, so you need to pay attention and look for them! The different ways aquatic insects fly, the way they emerge. As you start looking for insects, this all becomes nature, second nature, just as recognizing a dog did. And here’s another very positive thought about insect ID. You don’t need to know the latin name, or common name, of every bug that flies by. If a pale olive bug 11mm long flies by on July 5, find a fly in your box that’s pale olive and 11mm long, and tie it on. Simple as that. If the Missoulian Angler Fly Shop has done its job, you have that 11mm pale olive fly, and what they are is less important,

But there comes a time when you do want to know, and we get it. The MAngler has created a large online resource page called Hatches, which if we do say so ourselves, is pretty spiffy! Look at it, and the images will give you a good idea of what a caddis fly, mayfly and stonefly will look like. When you’re on the water, if you carry a net, looking at the real thing is a very simple task. Get a stocking  and stretch it over your landing net. Instant bug net, suitable for subsurface or in-flight grabbing. It’s easy to carry and store, and you don’t have an extra piece of tackle with you. There are also commercially available bug seines for this purpose as well. Start by kicking a few rocks directly upstream of the net, which is touching the bottom directly downstream of where you’re moving rocks. Look at what precipitates into the stocking. It will take a minute to get the hang of keeping the seined materials of the face of the stocking, but you will. You’re going to find more in the seine than just bugs! You’re going to have to move some stuff around to find the insects. Look and see what you’ve found. Are they big? Small? What color are they? How many of each are you finding? And once you’ve done that a couple of times. You’ll have identified the prevalent insect. If its brown, and 11mm long, tie on a nymph that’s brown and 11 mm long

Think about this. You’re a predator. An average hunter knows his quarry. A good hunter knows what his quarry is after for sustenance. We’re not on the plains of Africa, where predators congregate around water holes. Our prey lives in the water, so that doesn’t work! We have to learn about what our prey needs in other ways. When walking to the river, you’re paying attention.  See a spiders web? Look at it carefully. What’s in it. Shake a few branches next to the river as you walk AWAY from the put in. Let’s emphasize that. Most fishermen get no further from their car than it takes to drink a beer and get a new one. We tend to walk to where the path gets to be only a suggestion, and then start fishing. It makes a big difference. But we digress…..

You’re paying attention to your surroundings. You’re looking, and making the proper moves, to ascertain what the most abundant food form is. Shaking branches, looking for shucks along the shore, these are all things good anglers do to figure out what the trout are most likely to be feeding upon.

Aquatic insects are cyclical. If you see that pale olive insect in July this year, you’re going to see it again next year at the same time. The MAngler has a Hatch Chart in our Resource pages as well, detailing every insect important to the trout. The chart will say what species the insect is, and when it’s like to be found on the Blackfoot River, Clark Fork River, Rock Creek and the Bitterroot River. When you’re out on July 5, look at the hatch chart. It will give you a starting point to insect ID, because you can eliminate a lot of insects that won’t be on the water at that time of year. And you start looking at the bugs on the water.

On July 5, you see fish rising, and there’s a bug on the water that’s pale olive and 11mm long. You catch one, and it has an elongated body that curves upwards, 6 legs, large eyes and the wings stick straight up and back over the body. You’ve done some research, (or used your phone to access the Hatches Resource Page) and you ID the shape as a mayfly. Boom! It’s on like Donkey Kong! It’s like figuring out your first dog. The hard step is over. Now, any time you see that shape, regardless of size or color, you KNOW it’s a mayfly. The rest will follow, names, emergence times, etc.

The same will happen for stoneflies and caddis. You’ll ID your first one, and all of a sudden those worlds open up as well. And then, the river will start to look like a bug hatchery. When you’re not sure what exactly you’re looking for, it’s really difficult to find it! But as you spend more time on the water, and start to see the insects as stoneflies, or caddis, all of a sudden they seem to pop out for you.  You’ll be surprised you could have missed them all the other times you came to the river. You’ll start to understand what the birds are doing, wheeling across the surface of the water, and use their actions to locate insect activity. Patterns will start to emerge on the river, patterns that will provide you more successful angling in Missoula, and anywhere else you take the long rod out for trout. 

It’s a big step, learning to ID the different insects on the river. We know anglers who aren’t comfortable without knowing latin names, the range where they’re found, life cycles and the factors that trigger their emergence. Some just want to know the name so they buy the right flies! Other could care less, and just go a-fishing. Find your own comfort level, and don’t be influenced by others. At our Missoula fly shop, we have customers who really care, and we have people who used to care. It’s all good! Fly fishing is supposed to be fun, and it’s up to you to decide the level of fun you plan to attain. No matter what level of entomologist you plan to be, the MAngler plans to be there helping you get to the level you’re striving for, online and in the shop.

One last thought. You can look a little silly, running down the river in waders, waving a landing net in the air and cursing as your swipe completely misses the mark. Get over it! We’ve all been there, we just don’t talk about it anymore!!

Flies and Fly Tying

Building Your Euro Nymph Box

by MAngler

There’s no doubt that Euro nymphing, or high sticking to the old timers, is the most productive way to take trout consistently with a fly. Euro nymph techniques provide pinpoint fly control on a tight line, utilizing flies designed for rapid sink rates to quickly enter the zone where most fish live. Whether you call it Czech nymphing, high sticking or Euro nymphing, these techniques have won multiple world fly fishing championships and is effective on the hardest fished waters. Euro nymphing quickly gets your fly where fish are feeding, which is 90% of the battle.

That’s not to say building a box and buying a long rod will instantly answer all your prayers. Like any other fly fishing technique, Euronymphing takes some practice. A slight dip in the rod can result in a quick two-fly loss, while minimizing fly loss lessens your effectiveness. The best Euronymphers walk a fine line between hauling in fish and decorating the bottom. It takes time on the water to find that fine line.

With the bottom in mind, it’s no accident that most Euro nymphers have embraced the jig nymph style fly, for two reasons. First, and possibly most important, the hook rides point up, so it’s less apt to snag in it’s underwater journey. Two, in order to turn the hook over, the bead must be made of tungsten or an equally heavy material. This means jig flies, by their design, sink faster than a fly with a brass bead, thus dropping your fly where it needs to be faster.

Speed in attaining depth is critical with Euro nymphing. Euro nymphing often utilizes a very short cast, giving the fly little time to sink. A well designed Euro nymph gets deep at a much faster rate than a standard nymph. Considering the sink rate of your fly is the most critical aspect of creating an effective Euro nymph fly selection.

Sink rate is governed by two factors- weight and resistance to sinking. This blog writer used to tie the prettiest Hare’s Ear Nymphs, with a nice, active body and super buggy thorax. The only problem was, they wouldn’t sink. Just like a dry fly’s hackle, all those spiky tendrils were trapping air and spreading out in the water, seriously hindering my flies rapid descent in the water. Pretty in the vise ain’t pretty in the water! Too much fuzz on your fly, too much spread, and it won’t sink fast enough.

Which is why the Perdigon style fly, or SR Bullet, is the backbone of any Euro nymphers box. This hard bodied fly is unprepossessing at first, seeming to flout all the widely held beliefs that a fly must be active in the water to look alive and attract fish. Because Euro nymphing is designed to put your fly in a place where the trout doesn’t question its presence, action is less important. If it’s close to looking like food, and skimming across the bottom like the naturals, it’s going to get eaten.

Racing Gold Perdigon

Choosing your first Perdigons is easy. Light, dark, big and small. What could be simpler to get started! The Orvis Co., at one point, had a brilliant idea. They offered a basic mayfly nymph in light, medium and dark. It didn’t sell, as evidenced by its almost instantaneous removal from the catalog. But the concept is smart and useful. You don’t need a lot of accuracy when  putting your fly directly on the trout’s nose. The fish are feeding, taking in as much food as they can, and when your fly is in the trout’s comfort/feeding zone, it’s going to get eaten if it’s anywhere close. Light, dark, big and small.

When fishing in Missoula on the Blackfoot River, Rock Creek, Clark Fork River or Bitterroot River, bigger is often better. In Europe there are very few stoneflies, with many caddis and mayflies. Their fly selections tend to run to the small side, as do many east coast fishermen’s. This makes a lot of sense- match the naturals for more success. In Missoula, we have nymphs that are 50mm long! The small, big, light, dark theory works when fish aren’t focused in their feeding. When trout are on a subsurface “hatch”, having a fly that closely matches the natural is always better. Again, examine the fly for sink rate. The Pat’s Rubber Legs is not our best-selling fly for no reason. It’s the right size, sinks quickly and has good action in the water. A Peacock Double Bead Stonefly is also excellent for imitating the big stoneflies found in Montana. These two flies sink very rapidly and imitate a variety of stoneflies, especially the Pats in its various colors.

Another strong style of Euro nymphs is the Hot Spot. These are jigs with a drab body and a very bright spot of dubbing at the thorax. Some say it represents an egg load in the insect- others just say the contrast attracts the fish attention. We do know flies with a hot spot can be extremely effective, with hot pink and yellow being two favorite colors around Missoula. Again, big, small, light, dark with the added variable of a hot spot.

A third Euro nymph style features a collar of CDC wrapped at the back of the bead, like the Duracell or a Howell’s Shuck-It. CDC is chosen for two reasons. First, it’s easy to work with, can be torn to length and still look natural, and is a light weight fiber with lots of action in the water. CDC also has a property no other feather has. It comes from the preen gland of a duck, and is designed not to mat when it gets wet. The CDC feather holds air bubbles in its fibers that look incredibly lifelike to the fish. But this only works if the feather is dry! Once the CDC is soaked through, it loses it’s ability to trap air, but is still active.

TH Duracell

Serious Euro nymphers will carry Frog’s Fanny dessicant with them to refresh the CDC when it’s completely soaked. The Frog’s Fanny pulls the water from the CDC, allowing it to again trap air and bring that natural light refraction to the fly. Dressing your fly after every 4th or 5th cast can be a pain, but there are times when the CDC is a strong trigger, and it’s worth trying if the fishing is slower than you think it should be.

No Euro nymph box is complete without the Annelid. We prefer a basic Red SJW, though Hot Pink is also very effective. A fly that’s often overlooked in Euro nymphing is the Wire Worm. While not a strong producer in Missoula (No idea why not- it SLAYS on the Missouri) it is the fastest sinking fly we sell. What’s not to like- it’s wire wrapped around a hook, and sinks like a brick.

It doesn’t matter what type of bead you use on a size 14 or 16 Perdigon, comparatively it doesn’t sink as fast as a size 4 hook wrapped with wire. The Wire Worm is a great point fly in fast water. It takes your little bug down quickly, and then the long rod controls the depth of both flies. You might pick up a fish or two on the Wire Worm, but your smaller bug sinks deep quickly and doing a lot of business. We all know the addition of lead to your leader adds a hinge point, fouls up casting and is generally annoying to use. The Wire Worm works like a sinker, and has the added bonus of catching fish.

If you’re local to Missoula and are building a Euro nymph box, don’t miss the Missoulian Angler’s Dollar Fly Box on the counter. I know it sounds weird, recommending flies on sale! The Dollar Box is filled with flies that didn’t perform as well as we hoped they would. They were all bought with high hopes- they just weren’t what we hoped they would be. The Dollar Box is incredibly useful as you learn to control your fly’s depth with the long rod and skinny leader. It’s better to lose $2 worth of flies on a cast than $6! So grab a handful of Dollar jigs for when you’re just starting, to save some wear and tear on your wallet.

Because at it’s best, Euro nymphing is about working the bottom of the river, where the fish live. With practice, your fly will follow the contours of the bottom, just as the naturals do. Present your fly naturally, where the food is, and your success rate is going to go through the roof. Too deep, and your flies are gone. Too high in the column, and the fish don’t move as readily to your fly. Depth is critical, and using flies designed to get deep and stay there is a critical aspect of Euro nymphing. Armed with this knowledge, you can build a Euro box that will take trout throughout Missoula, all over Montana and across the country.

Best Flies For September Fishing In Montana

by MAngler

September fly fishing in Missoula is arguably the best time of year. The water is low, reaching prime temps with longer, cooler nights with the most comfortable wading of the year. The bugs are diverse in size, ranging from size 6 hoppers to size 22 Blue Winged Olives. Subsurface, the nymphing is excellent with so much insect activity, while the streamer fishing comes on as September progresses. It doesn’t matter what type of fly fishing you’re looking for, if you’re in Missoula in September, you’re going to find it. Lets take a look at some of the best flies for September fly fishing in Montana.

Hoppers

September starts with the same flies as you’ve been using since August 10th. The grasshoppers have established, with fish on the prowl looking for a big, easy meal. Missoula hopper fishing starts in late July and depending on weather, may last into November! That’s over 3 months of fish seeing naturals, and their imitations. September is a good time to do a little experimenting with different hopper variations. We carry Pav’s Hopper in 5 different colors, and variations on the Morrish Hopper in 4 different colors. We have gray hoppers, blue hoppers and many pink ones. Why do they work? No idea, but they do. We watch Missoula’s best fly fishing guides shop every morning, and in September they will be looking for full fly bins. The theory is no one is buying them, so the fish haven’t seen too many. Think about expanding your hopper game in September to show the trout

something new and different.

Tricos

The same can be said for Tricos. In early September, you can almost set your watch by the trico hatch. The fish have been looking at naturals for almost a month, and they can get a bit snotty at this time of year. Think about some Trout Hunter tippet in 5.5X. Trout Hunter tippet is much softer than Rio, and allows your bug to float more naturally. The half sizes of tippet provide more stealth without sacrificing as much strength. Move to trico cripples and emergers, like the Sprout or the Quigley Cluster Midge. Ron’s Trico Spinner will produce consistently as well, though by this time of year he is way tired of tying them! Be ready to drop down to a size 20 as well, so make sure you’ve got your readers when you hit the water.

Blue WInged Olives

We’re all waiting for the magic moment in September- the first real rains of fall. If we’re lucky, the rain comes in about September 10th, and the entire complexion of fly fishing in Missoula changes. The weather change brings cooler temps and some clouds. The tricos trade out for Blue Winged Olives. Same size- different color. The week after the rains will prove to any angler that fish can see color! If you fish a trico through a BWO hatch or vice versa, you’re not going to be anywhere near as successful as you could be. Look for the classic figure 8 of a trico spinner cloud above the water, or get your nose close to the water and check what’s floating by. It makes a big difference!

As the BWO’s start, the basic patterns will work. A simple Parachute BWO or Comparadun will take fish consistently at the start of the hatch. But as the BWO’s extend through September, growing in numbers, the fish get a lot more selective. The Last Chance Cripple or Quigley Split Flag Cripple will start to be more effective for fussy trout. Again, shift down with your tippet size to give your fly the best chance at a drag free drift. Watch rise forms very carefully when BWO’s are on the water. Many fish focus on emerging nymphs, and while you’ll see concentric “rise” rings, it’s the fish’s back that breaks the surface, not the mouth. Drop an unweighted Size 18 Pheasant Tail about 4 inches off the back of your dry and watch your catch rate skyrocket.

Mahoganies

In the middle of the month, the Mahoganies start to make their annual appearance. This size 14 mayfly is tough to miss on a Fall afternoon, and provides a steady hatch for the next 3 weeks. The Parachute Pheasant Tail, Purple Haze or Brindle Chute all in size 14-16 are excellent choices at this time, with the Brindle Chute out performing most other flies when the Mahoganies are on, especially on the Bitterroot River where it was invented. Again, as the hatch progresses, start to get a bit more technical with your flies. Bring some Last Chance Cripples or Sparkle Duns when the fish are ignoring your standard fare.

October Caddis

At the end of the month, you can start looking for the October caddis to appear. If you think you can’t miss the Mahoganies, you REALLY can’t miss the October Caddis. This size 8-10 orange caddis is a favorite of fish on the Blackfoot River, Bitterroot River, Rock Creek and the Clark Fork River. If you see one, tie one on. The fish are looking for them and will eat even when the naturals aren’t strong. Both the Orange Elk Hair Caddis and the Orange Goddard Caddis will float a small dropper as well, so make sure to utilize that option as well. The Birds of Prey October Caddis Pupa is deadly subsurface, and if you’re not getting the action you’re looking for on top, get down with the pupa to bring your fish count up.

Nymphs

With all the hatches across Missoula’s rivers, the nymphing can be off the hook! With lower water levels the droppers are shorter and easier to control, especially on the Bitterroot River and Rock Creek. Don’t be afraid to go small. Early in September, the SR Bullet Black in a size 18 is a great trico nymph. When the weather changes the rivers to BWO’s, switch to an SR Bullet Olive and keep raking in the fish. A Pheasant Tail Jig will outperform most anything for the Mahogany nymph, and don’t forget the October Caddis Pupa. It should be said again, if fish aren’t eating on the surface, they’re eating underneath- dry flies get the ink, nymphs get the fish. Especially at the end of the month, when the cold weather tells the fish winter is coming, and they need to eat.

Streamers

The same weather that moves trout to nymph hard also moves fish to eat streamers. When the days start to get cooler and shorter, a great way to start the day is working a small to midsize streamer around the likely areas. If your streamer choice is comfortable to cast on a 5-6 weight, it’s proabably the correct size. This is conventional wisdom, but there are exceptions. In the big water of the lower Clark Fork River and the lower Blackfoot River (which is now bereft of tubers due to the cold) a big streamer run deep will still work its magic. If you’re a streamer-maniac, the last week of September can be prime time, moving bigger fish looking to take in a few calories before the real weather gets here. Pick your spots to run the Mongrel Meat or Sex Dungeons, or go smaller with a Baby Gonga or Dirty Hippie.
