Fly Fishing in Southwest Montana

So it begins high in the Beaverhead Mountains, the Big Hole River flows for 153 miles through a fly fishing wonderland filled with Brook, Rainbow, Brown and Cutthroat trout. The Big Hole is the last remaining habitat for fluvial Arctic Grayling in the contiguous United States. Along the Big Hole corridor are fishing access sites with names: Jerry Creek, Divide, Maiden Rock, Salmon Fly, Notch Bottom, Pennington Bridge until the Big Hole joins with the Beaverhead River.

Sliding along the Pioneer Mountains, the Big Hole River becomes world class for pocket water as the river gains momentum slicing into the Canyon section, it becomes the destination for anglers during the prolific Salmon Fly Hatch in June.

One of the most quintessential pieces of landscape in the American West is the “Notch”. This is where the Big Hole carves a groove through two pillars of rock. The Big Hole then meanders through the cottonwoods and meadows melding with the Beaverhead just north of the town of Twin Bridges to create the Jefferson River.

Fly Fishing the Big Hole River


July and August – Tricos, Mayflies, Moths:Tricos and tiny mayflies, start erupting along the Big Hole in the summer months. These tiny flies become a substantial hatch for hungry trout. With a little luck and a little cloud cover they offer wonderful dry fly fishing opportunities. Another signature hatch on the Big Hole are Spruce Moths enticing trout to the surface. This hatch can be seen on the entire length of the river, creating 153 miles of angling bliss.
