Fly Fish the Missouri River from Holter Dam to Cascade.

Due to the cold water being released from the bottom of Holter Lake, it creates excellent habitat for trout. The section of the Missouri River from Holter Dam to Cascade, MT is the main area for trout fishing, and has excellent access to the river. 

This section of river runs through the valley with sparsely forested hillsides.
