Clark Fork River

The Clark Fork River, the largest river in our region, serves as the collection point for everything in the Missoula area before it flows into the Columbia River. Split into two distinct sections, the upper river to the east of Missoula is often overlooked by anglers, but shouldn't be. While it may not have a significant trout population until it merges with Rock Creek, the quality of the fishing experience more than makes up for the quantity. Expect to encounter stunning brown trout while using streamers and hoppers in this mesmerizing stretch of water. As you venture downstream, bug life and trout numbers improve after Rock Creek joins the Clark Fork, and the confluence with the Blackfoot and Bitterroot rivers near Missoula creates the vast and awe-inspiring lower Clark Fork. This lower section of the river presents some of the finest dry fly fishing opportunities in the entire western region. With bountiful mayfly and caddis hatches starting from June and lasting well into October, you'll witness rainbow, cuttbows, and cutthroat trout gathering in large groups to feast. Prepare to be amazed by the average size of the fish you'll encounter in this extraordinary river.

Spring

The upper Clark Fork is recognized for its productive early season streamer fishing, but fishing conditions, water clarity, and flows can change daily. In contrast, the lower Clark Fork is more advantageous during this period. Keep an eye out for remarkable hatches of Blue Winged Olives and Skwalas that result in exceptional dry fly action.

Summer

The upper Clark Fork provides excellent fishing opportunities during the summer months, especially with Caddis and Terrestrials. Below the confluence with Rock Creek, isolated stonefly hatches offer more reliable surface fishing experiences. However, in some years, high water temperatures and aquatic grass can create less favorable conditions in the uppermost sections of the Clark Fork. On the other hand, the lower Clark Fork is thriving at this time of year, boasting a continuous cycle of mayfly hatches such as Pmd’s, Tricos, and Drakes. Additionally, Caddis and Terrestrials provide a steady food source throughout the summer. Combining Terrestrials with dropper nymphs is a reliable tactic for successful fishing during the peak of summer.

Fall

This time of year is highly anticipated on the lower Clark Fork. Hopper and Trico hatches continue into the fall, followed by BWO's and Mahoganies, creating the perfect storm of insects, flow and air temp. Streamer fishing regains effectiveness. As the water cools in both the upper and lower rivers, fish become more aggressive and actively chase larger streamers stripped nice and fast! If you luck out and find yourself fishing the middle of the week on the lower river in October you might just find some of the finest fishing in all of Montana.
