Missouri River: Holter Dam to Cascade or Ulm

This stretch of water, from Holter Dam to the town of Cascade, thirty miles downstream, is the prime trout fishing waters on the Missouri. The Missouri River in this sections runs through a valley and a canyon that has sparsely forested hillsides.

This section of the Missouri River also has a significant history. Numerous historical sites of the Lewis and Clarks expedition are found all along this stretch of river.

This section is also where the vast majority of fly fishing occurs on this river. The cold waters released by Holter Dam, which is not run entirely for the benefit of electricity production, provide excellent trout habitat. Access to the river between Holter Dam and Cascade is excellent.
