Missouri, Below Holter Dam Description

One of the largest and most easily accessed rivers in Montana is the Missouri River. The mighty MO' is certainly a trout factory! Three reservoirs in a row make this tailwater fishery have a constant water flow and stable temperatures from day to day.

Techniques & Tips

Fishing two small midges/mayfly nymphs has been productive in the upper river. Start your rigs about 4 feet deep and adjust from there. You can streamer fish certain stretches depending on the weeds.
