Top Places for Bass Fishing in Montana

The best bass fishing in Montana takes place in the morning and late evening. During summer, lunkers seek haven in the deeper, cooler waters, so the fishing is often better at night. Bass are generally found near some kind of cover - shady spots under weed beds, over-hanging trees, logs, brush, stumps, rocks and rocky points.

Castle Rock Reservoir

This lake is in Rosebud County in the town of Colstrip. The Colstrip Parks and Recreation Department maintains a public access site on the reservoir. Sampling in 2011 found good numbers of bass to 14 inches. Boaters on this water body are restricted to oars, paddles or electric trolling motors.

Dan Hanghian Reservoir

Largemouth bass were introduced to this Custer County reservoir in 1977 and since then the pond has become an excellent producer. Largemouth bass were restocked in 2011 following a substantial winter kill.

Landowner permission is required to access this pond. Contact the Region 7 headquarters for access details.

Gartside Reservoir (Richland County)

Gartside Reservoir near Sidney has a Fishing Access Site (FAS) state Route 16, one mile north of Crane and then west one mile on County Road. Samplings in 2011 revealed largemouth bass up to 5 pounds. Only electric motors are allowed on Gartside Reservoir.
