Jefferson River Fishing Report

 (2)
The Jefferson River is an important part of a system of rivers that combine to form the majestic Missouri. Starting at the confluence of the Big Hole and Beaverhead rivers near Twin Bridges, Montana, it winds 77 miles in a northeasterly fashion to Three Forks. Here, it meets with the Madison and Gallatin rivers that together converge into the Missouri River at the Missouri Headwaters State Park. Like so many other rivers in Montana, the Jefferson, named by Clark in honor of the U.S. President, runs deep with history. In fact, the Jefferson River is a segment of the larger Lewis and Clark National Historic Trail, administered by our National Park Service.


When thinking about the Jefferson, a Class 1 river for recreational enjoyment, most observers view the river in three distinct sections. Characterized by slow, meandering flows, the upper third works its way through a broad, arid valley. Along this braided, 44 mile long floodplain, you will encounter working farms, dense cottonwood stands, flowered meadows and a variety of wildlife until you reach the town of Cardwell. Throughout the next 15 miles, its waters flow through a narrow, steep canyon where the water can be deep, slow and contained. As a result, the stretch from Cardwell to the Sappington Bridge has comparatively fewer trees, swamps, meadows and wildlife.

At Sappington Bridge the river once again becomes a circuitous, rambling river, rich in swamp life, colorful fields, large cottonwood groves and productive agricultural land. The presence of significant agriculture has resulted in competition for water use. During dry years, the river was tapped generously for irrigation, dropping water levels to the point where fish populations were adversely affected. Recent improvement in riparian management has tended to alleviate these issues. Primarily known as a brown trout river, rainbows, mountain whitefish, burbot and northern pike can also be found here. Less well known and less discovered, the Jefferson offers the opportunity to catch large fish in a scenic, un-crowded environment.

On its way to the Missouri Headwaters, the Jefferson River passes through an assorted landscape. At the town of Twin Bridges, Montana the Ruby River, Beaverhead River and Big Hole ... moreRiver converge to form the Jefferson. In its early stages the river advances past hay fields, large stands of cottonwood and agricultural landscapes. As the river reaches the town of Cardwell, the Jefferson is then flanked by large canyon walls, home to Lewis and Clark Caverns. Downstream of the canyon the river again proceeds through farm and ranchland laced with cottonwood trees until joining the Madison and Gallatin rivers. Though fishing on the Jefferson can be less consistent than on some of our other rivers, it can certainly make up for it with some very special moments. When the Jefferson is good, it can be great!

The lower beaver head is starting to clear up at twin bridges, and so goes the Jefferson. We fished there two days ago and fishing was good. Nice part about the day was that we didn't ... moresee another angler all day. Water is still high but is clean. Fish were tight on the banks and in the soft recirculating pools. Fishing was on and off we would catch 3 nice fish then nothing for an hour. I saw some midnight stone empty cases on the bridge abutments which means dry fly fishing isn’t far off. Also saw some fish working caddis but we never switched over. Water is falling and the time is now! Eric Shores

The guide will meet you in Ennis or Twin Bridges and provide transportation for the ... moredrive to the river. The drive from Twin Bridges typically ranges from 5 minutes to 45 minutes and the drive from Ennis to the river typically ranges from 45 minutes to just over an hour. At the boat ramp guides will provide instruction on the days fishing tecniques and launch a drift boat for the float. The guide will provide all the flies and tackle that you need for the day. All you really need to bring is a Montana Fishing license, appropriate clothing and sunglasses for eye protection. The fishing involves floating down the river and casting flies from the boat. Floats are typically around 7 hours of floating but can vary depending on the preference of the customer. All of the fishing is usually done from the boat, which makes wearing waders optional and not at all nessesary. At mid day you will take a break on the bank and enjoy lunch provided by your guide. The Jefferson is a smaller, beautiful braided river that flows through the cottonwoods of the valley. The Jefferson is one of our smaller float rivers and it typically sees much fewer angelers than other rivers which means that you are likely to see only a few other boats during the day. The Jefferson typically will fish well from May through Mid October. May through September are considered the peak season. Trout typically range from 10-20 inches with fish over 20 inches possible. Fish in the 14-17 inch range are normal and the bigger fish of the day typically range from 18-21 inches. The river flows through the scenic Jefferson valley with the Tobacco Root mountain range always in view and moose are frequently sighted on the float. The Jefferson is known as a smaller, less fished river that occassionally produces really large brown trout.
