Fly Fishing On The Bitterroot River In Montana  The main stem of the Bitterroot River is formed by the confluence of the West Fork of the Bitterroot, a tailwater, and the East Fork of the Bitterroot, a freestone stream. The main river flows through the Bitterroot Valley on its way to the Clarke Fork River in Missoula, Montana. The Bitterroot Mountains form the western skyline and the Sapphire Mountains form the eastern skyline. Fly fishing the Bitterroot River is usually a very neat adventure. Each of the two forks provide about twenty miles of fishing. The main stem of the river flows for seventy-five miles through a fairly well developed area of Montana on its way to Missoula. Most of the Bitterroot Valley is used for agriculture purposes but there are a few ranches. Both grass and timber line the banks of the stream. The Bitterroot is an excellent trout stream consisting of diverse water and some quality hatches. Cutthroat, brown, brook, and rainbow trout can all be found in its waters. The Bitterroot River overall is approximately seventy-five miles long from the junction of the East and West Fork just below the little town of Conner to where it meets the Clark Fork River near Missoula, Montana. You will find some beautiful riffles, shallow and deep pools, and some fast, deep runs. It  has just about everything that makes it a good trout stream.There are Special Regulations area’s, so where you fly fish the Bitterroot River can make a difference in the regulations.The uppermost section of the Bitterroot, running from Conner to Hamilton, consist mostly of fast pocket water and it offers excellent dry fly, nymph, and streamer fishing opportunities. The river tends to stay cooler in its upper section. It’s headwaters of both forks stay cold year-round. Below Hamilton, the river slows somewhat and more and more riffles become available for the dry fly angler. Once the river reaches the valley, it flows fast large trees consisting of cottonwood, aspen, and fir.In the lower section, the river flows past some ranches and farms. Both the East Fork and the West Fork of the Bitterroot offer great trout fishing opportunities. These two forks, along with the larger main stem, provide a tremendous diversity of water. There’s small stream headwater fishing, tailwater fishing, and varying water types in the main steam that ranges from long, slow moving deep pools with short sections of riffles connecting them to faster water with lots of riffles and runs. There’s also some braided channels and plenty of undercut banks. Below the town of Victor, the Bitterroot flows about thirty-five miles before it enters the Clarks Fork River. This section gets warmer in the summer because the water flows slower and the stream is much wider. Access to the entire Bitterroot River is great because highway #93 following the main stem and the East Fork throughout their lengths. The West Fork is accessed from County Road #473. Check back often as we update the Bitterroot River fishing report often.

Fly Fishing Guide to the Bitterroot River: The methods and strategies you use for fly fishing the Bitterroot River depends on the section you are fishing and the time of year. The East Fork of the Bitterroot River is a freestone stream subject to the whatever Mother Nature brings to it. It flows for about twenty miles before joining the West Fork to form the main stem of the Bitterroot. The upper part is followed by the East Fork Road through National Forest Land. Highway #93 follows the East Fork from Conner to near Sula. There are several fishing access sites along the road and some private property in this section. This is a small stream that contains mostly small Westslope Cutthroat trout. The fish are plentiful and the stream provides an action packed, fun filled fishing experience.The West Fork is a tailwater below Painted Rocks Lake located near the Idaho and Montana border. There are approximately ten miles of the stream above the lake. It contains small brook, cutthroat and rainbow trout. It can be accessed from the West Fork Road. Most of it lies on National Forest land. To your right is a thumbnail image of Painted Rocks Lake. The West Fork tailwater runs about fifteen miles before its confluence with the East Fork. The water below the dam runs clear all year long and can even be fished during the spring runoff. It has some good sized rainbow, brown and cutthroat trout. Most of the water is of moderate flow. It is easily waded.The two forks of the Bitterroot join just above the little town of Conner. The main stem, downstream of Conner, is still a small size and provides excellent wading and floating conditions. It has a good population of rainbow, brown and cutthroat trout. There’s a public access just below Conner, the Hannon Memorial Fishing Access. This upper section is still cooled during the summer from the West Fork flows of cold water released from the bottom of Painted Rock Lake. It has lots of riffles and is surrounded by some very nice scenery. Its fish may not be quite as large as they get downstream, but you most likely won’t be crowded.The next section flows between the towns of Hamilton and Victory. There the water is often used for agricultural purposes and the river can get rather low. It is broken up in many areas with split channels. This is a good section to wade. Most of the time the  flows are slower than most everywhere else. There are many gravel bars along the river, along with several diversion dams in this section. Fishing access sites are available.From Florence to Victor, the river can get too warm for good trout fishing during the late summer, but its great most any other time. There are no diversion dams and the river can be floated fairly easy. The fish population is probably slightly higher than it is upriver. There is plenty of deep water in large, slow moving pools that can hold trout. The fish in this section are larger than most of them found upstream. The biggest problem is the traffic during the late spring and summer created by recreational boaters.From Florence to the Clarke Fork River, the Bitterroot River takes on a slightly different appearance from the section above Florence. The braids, channels and islands return. The stream doesn’t have as good of a population of trout as the section above Florence, but it does hold some very nice trout. Large rainbows have been caught in this section. The river slows down again, and the water can become too warm during the late summer.

Hatches and Flies: Our information on aquatic insects is based on our stream samples of larvae and nymphs, not guess work. We base fly suggestions on imitating the most plentiful and most available insects and other foods at the particular time you are fishing. Unlike the generic fly shop trout flies, we have specific imitations of all the insects in the Bitterroot River and in all stages of life that are applicable to fishing.

You want find Trico mayflies in the fast water of the headwater sections, for example.The Blue-winged Olives are among the most important hatches. The BWOs start hatching about the middle of March. It can last until the end of April. A second hatch takes place starting about near the end of September. It can last until the first of November, depending on the weather. Another important mayfly is the Pale Morning Dun. They hatch starting about the middle of June and lasting until as late as the first of August. There is a Brown Dun hatch that takes place about the last week of March and through the month of April. The only other substantial hatch of mayflies are the Tricos. These hatch on the slower, smoother sections of water during August and September. Caddisflies can be the most important insects at times. Spotted Sedges are the most plentiful species. They start hatching around the middle of July and can last through the month of August. There is a Little Black Caddis hatch, called the Mother’s Day Hatch, that starts in mid April and last through the month of May, depending on the section. The big October Caddis hatch from about the middle of September through October.

Skwala Stoneflies start abut the middle of March and last through the middle of April. The Salmonflies usually start about the first of June and last through July, depending on the section of the river. About the first of June the Golden Stoneflies start hatching. They hatch through the month of July, depending on the section of the river. Yellow Sallies, or Little Yellow Stoneflies, hatch from the middle of May all the way through the middle of August, again, depending on the section of the river.Make sure you have a good selection of streamer flies.
