Fall Fishing is Hot in Southeast Montana

As the temperatures cool down, the fishing in Southeast Montana is heating up. One of the best kept secrets in Southeast Montana is the reason people come from all over the world to this somewhat remote, but incredibly majestic region. The Bighorn River, a tributary of the Yellowstone River, is regarded as one of, if not the best, trout streams in the lower 48 states. The gentle, cool, clean waters are home to hundreds of fish in every mile.

While fishing for both brown and rainbow trout, enjoy the surrounding views of the Pryor and Bighorn mountains to the west and south as you listen to the babbling river flow and bask in the golden light cast by the river’s autumnal cottonwoods. Turn to the east and enjoy the views of the prairies and the millions of years of history they hold.

Best Time of Year

Fishing year-round in Montana isn’t for the faint of heart, but thankfully braving the cold waters of the winter isn’t necessary to test your luck on the waters out here. Most agree – late summer and early fall is the best time to catch fish on the Bighorn River. This time of year offers a look at the beauty of the changing colors on the landscape – both on the prairies and in the mountains.

For the more experienced and adventurous types, the Bighorn River can be tackled in the colder months because it doesn’t ice over. However, if you’re heading out in the winter, be prepared for cold weather and changing conditions including variable wind.

This best-kept secret hasn’t always been the oasis it is today. Changes to the river in the last century created this fisherman’s sanctuary.

Yellowtail Dam

After centuries of flooding, several studies were done in the early 1900s on the damming of the river. It was finally decided to build a dam that would stand 525 feet tall. Construction began in 1961 to temporarily reroute the river. The first batch of concrete was poured in 1963, and the project was completed in 1967. The Yellowtail Dam is named after Robert Yellowtail, a former chairman of the Crow Tribe, who was opposed to the project.

The dam was dedicated in 1968, the same year the Bighorn National Canyon Recreation Area was designated. It encompasses the 71-mile long lake created as a result of the dam. Known locally as “Yellowtail,” Bighorn Lake straddles the Montana-Wyoming border with access in both states. The recreation area is managed today by the National Park Service.

Public Access

While more than 12,000 acres of land was acquired for the project from the Crow Tribe, agreements were made to assure the tribe and private landowners would still control the surrounding land.

As such, there are three points of public access on the upper 13 miles of river below Yellowtail Dam: Afterbay, 3 Mile (Lind Ranch) and 13 Mile (Bighorn Access). The National Park Service manages the Afterbay and 3 Mile access points, and Montana Fish, Wildlife & Parks manages the Bighorn Public Access Site. Put your drift boat in at any of these sites and navigate the dozen-plus miles of river looking for your catch. Or, if wading is more your style, take your chances walking up and down the river, making sure to stay below the high water mark.

Almost all of the land surrounding the river in this area is private, including much that is owned by the Crow Tribe. Shoreline access is available in a limited capacity at the three public access points. Visitors are asked to avoid trespassing by staying below the high water mark in all locations.
