Missouri River Fly Fishing

In the Spring of 1804, Lewis and Clark, along with forty men, launched their western expedition, better known as the “Corps of Discovery,” via a keelboat on the Missouri River just outside of St. Louis. They would follow the Missouri River with a team of botanists, zoologists, fur trappers, hunters, boat builders, surveyors, and gunsmiths to identify and confirm a potential water route to the Pacific Ocean. Today, anglers from around the world migrate to the small fishing towns of Craig and Wolf Creek, Montana, aptly situated in Lewis and Clark county, every summer to experience incredible dry fly fishing for healthy populations of above-average sized trout.

Contrary to popular belief, the Missouri is the longest flowing river in the United States, about one hundred miles longer than the Mississippi. At 2,341 miles in total length, only a tiny section of the river below Holter Dam produces blue-ribbon fly fishing opportunities – and arguably – some of the top fly fishing opportunities in North America. When hatches of mayflies and caddis are absent, the nymphing and streamer fishing can be exceptional. If you are a trout fishing enthusiast, your fly fishing journey isn’t complete until you have experienced the bug factory that is below Holter Dam.

Sections of the Madison River

Holter Dam to Craig
This is a very popular stretch of the “Mo” with anglers and rafters alike. Depending on the time of the year, one can experience exceptional hatches of blue-winged olives, caddis, pale morning duns, and tricos throughout the late spring, summer, and early fall months. Due to the popularity of this section of river coupled with the amount of insect activity, long leaders and precise casting are essential for success utilizing dry flies. The dry fly fishing on this section of the river can be compared to fishing the infamous “Ranch” section of the Henry’s Fork in Idaho. The slow and flat moving water can be deceiving from the river bank until you make a cast and watch your fly dance among microcurrents as it scurries downstream. The trout aren’t forgiving of sloppy casting, and the microcurrents will challenge an angler’s typical presentations. Anglers focusing on catching numbers of fish can benefit from nymphing the numerous drop-offs and other river bottom features. Getting your fly into the zone is critical, so ensure that you have a solid selection of weighted nymphs and don’t be afraid to play around with the depth you’re fishing. This section of the Mo includes the side channels where anglers can find hungry trout with fewer rafters during the hot summer months. An excellent guide that intimately knows the river can become a total game-changer in not only helping you catch fish but cutting the learning curve. They will show you how to set up on rising singles or pods of trout, the best methods for fly presentation, fly selection, and other tricks that they’ve added to their arsenal over years of guiding on the Missouri.

Craig to Dearborn
From the Craig bridge downstream for a couple of river miles, the river resembles the Holter to Craig stretch in features and characteristics. When you pass the Stickney Creek access, the river begins to narrow slightly, and the water picks up. This is an excellent section for casting and swinging streamers in the long, narrow runs and up against the bank.

Seasons on the Missouri River

April-May
Springtime in Montana can be translated to potentially experiencing all four seasons in one day. You may have days where the temperature climbs above seventy degrees, or you could face heavy snow. Be sure to come prepared with a mixed bag of clothes and always bring a jacket. During the early spring, the water temperature can result in trout holding deep and not displaying the same active behavior like they do in the summer. Double nymph rigs with weighted sowbugs, nymphs, midges, and scuds in sizes 12-18 work well this time of year. If you get an overcast day or light rain/snow showers, you may experience fantastic blue-winged olive dry fly fishing that brings the fish to the surface, where they’ll concentrate around slower currents and slicks.

In addition, the Missouri also has hatches of skwala stoneflies (size 8/10) and march browns (size 14) in the spring. These hatches are not as consistent as hatches of blue-winged olives or midges, but they can provide some action throughout the day if the weather has been stable.

Anglers targeting fish using streamers need to get their fly down quickly to where the fish are holding. Due to colder water temperatures, trout may not be as willing to move very far for food. Slowly stripping or swinging your fly will most likely pick up more fish throughout the day than faster retrievals. Search for trout in the numerous long and deep runs with slow-moving water.

 

With rising water temperatures in mid-to-late May, trout can be found in one place in the morning, then move to their old summertime haunts behind rocks, against the bank, and shallow riffles by mid-day. For example, you may be targeting fish with a double-nymph rig in deep, slow-moving pools in the morning and casting dry flies up against the bank in the afternoon. Because Missouri River trout have so much food available to them subsurface, it takes a substantial hatch to bring them to the surface during the colder months. In short, be prepared for all types of fishing methods this time of year!

Rainbow trout are spawning or coming out of the spawn this time of year. Please do not target rainbows on redds or in shallow water that display lethargic behavior.

June-July
Due to potential cold, rainy weather and increased outflows from Holter Dam, early June can be hit-or-miss when it comes to bugs and rising fish. From late May through mid-June, the majority of your fishing will most likely be nymphing unless you can find a window where you have decent weather coupled with consistent flows. But just because the water is high doesn’t mean that the fishing will suffer! At this time of the year, fishing worms, scuds, sowbugs, and other nymphs in pocket water, seams, and foam lines can produce great days on the river.

During late June, Mighty Mo comes to life, and the small fishing towns of Craig and Wolf Creek double in population. At this time of the month, flows begin to recede, and once below 6,000 CFS, it is game on. The first pale morning duns to come off are larger (size 14-16), and the trout cannot get enough of them. For the best fishing opportunities, be sure to have pmd flies in all life forms: nymphs, emergers, cripples, adults, and spinners. Generally, most trout can be fooled with a solid presentation and either a cripple or spinner; however, you’ll most likely experience at least one fish that may be more difficult to fool. If this is the case, pay attention to the fish’s rise form. Is the nose coming out of the water, or do you see boils? Many trout feed on rising nymphs right below the water’s surface. The nymphs fill with air bubbles that give them buoyancy, and at this stage of their life cycle, they are helpless. Try using a dry fly that you can see, then take a non-weighted pheasant tail or split case pmd nymph (size 14-16), applying just a little bit of gink to the top of the dropping it a foot off your dry fly. Unless the fish is feeding on the bank, a down and across presentation will most likely suffice.

During prolific hatches, anglers can find fish in singles or pods near the bank, on one of the many shallow “flats,” in seams where slow water and fast water meet, and in riffles. Come early-to-mid July, the Missouri is in full swing. Between the sheer amount of caddis and pmds, the dry fly rod is either in your hand or ready to go in the boat. You can have a terrific spinner fall in the morning, target fish midday during a pmd hatch (especially if you get some cloud cover), and finish the day by fishing caddis in the evening. When fishing caddis, look for shallow and fast-moving water with some overhanging brush. The fish that are rising in these areas will most likely take a well-presented caddis dry fly.

In the last half of July, anglers can still have phenomenal caddis and pmd fishing. The hatching bugs begin to get smaller, so be sure to carry some size 16-20 dries. The introduction of terrestrial fishing in late July presents more dry fly opportunities. Casting hoppers, ants, and beetles can fool fish that have seen every pmd fly in the shop float by them numerous times until this point. Small mayflies referred to as “tricos” begin hatching in late July as well. Strong hatches of tricos can bring pods of fish up all over the river.

August-September
With increasing water temperatures, especially in early August, the best fishing will most likely be in the early morning and evening. During years with a decent snowpack, more cold water can be released from Holter Dam. On below-average snowpack years, they preserve the water and won’t release as much downstream, resulting in warmer water temperatures and fewer fish up feeding on the surface. This is dependent on the previous winter!

Hatches of trico mayflies start in the early morning. If you want an exceptional challenge, then this is it. These tiny mayflies are between hook sizes 18-22 and require fishing light tippet to achieve drag-free drifts. This can be some of the most challenging dry fly fishing in the U.S. West. Some anglers will fish a larger dry fly that they can see and drop a tiny trico off of their larger dry. You can also get away with fishing larger “cluster” dry flies such as a buzzball in sizes 16-18 that may resemble several tricos floating together.

By mid-day, the trico fishing is most likely over, and anglers either cast double nymph rigs or terrestrial dries. The Missouri River below Holter Dam is lined with farm fields, and there is no shortage of big, juicy grasshoppers for fish to feed on. Many anglers choose to fish a hopper fly as their main fly and drop a smaller ant or beetle off the back to pick off fish that may not want the full steak dinner. Look for trout in all usual places: deep pools, slicks, behind or in front of structure, along the bank, and under overhanging brush when the sun is high in the summer sky. By late August, you’ll still have hatches of tricos, caddis in the evening, and some decent terrestrial fishing before things cool down and the river moves into another phase.

Much like May, the month of September can bring many diverse fishing options from streamers to dries. Hatches of tricos may begin to occur a little bit later in the morning once things start to warm up after cooler nights in the first half of the month. If casting tiny dry flies to Missouri River trout wasn’t challenging enough, the excess of weeds in the river will add another element to the game. Once hooked, many anglers lose fish that swim down in the thick weeds that have had time to grow and collect on the water’s surface. It can also be difficult trying to keep your dry fly clean of weeds when making your presentation. In any challenge, whether it is wind or weeds, the best thing to do is use it to your advantage. In this case, finding beds of weeds can be productive, as it acts as a vacuum for collecting thousands of bugs. And where the food is, the trout are not far behind!

By the end of September, anglers are back to slowly stripping and swinging streamers, targeting fish on the surface, eating blue-winged olives, and nymphing. There may be a few large (size 8-10) October caddis around as well. One great thing about this month is the amount of boat traffic subsides, with many anglers transitioning to hunting and cooler weather keeping rafters off the water. You’ll most likely have a lot of water to yourself, especially in late September.
