Tour Overview
A Cold, Clear Spring Creek With Deep Roots in Lewistown History
Big Spring Creek begins southeast of Lewistown near the Big Springs Trout Hatchery, flowing from one of the world’s largest freshwater springs. Long valued as a sacred place by Native American tribes and later recognized as a vital resource by early Lewistown settlers, the creek remains one of Central Montana’s most treasured natural features.
From its source, Big Spring Creek winds northwest for roughly 30 miles through picturesque trout habitat between the Big Snowy and Judith mountains before joining the Judith River west of Brooks. Its steady flow of cold, clear water, often around 52 degrees near the source, creates ideal conditions for trout and gives the creek its distinctive spring-fed character.
For anglers, Big Spring Creek is one of Montana’s standout spring creeks, even if it often sits quietly outside the spotlight. With healthy populations of brown and rainbow trout, approachable water, and a long tradition of local fishing stories, the creek offers a rewarding experience for visitors who appreciate technical water, scenic surroundings, and a genuine Central Montana hidden gem.
