The ideal streamflow range for the river is between 1,500 and 4,000 cubic feet per second (cfs), which typically occurs in the late spring and early summer months. The river is rated as a class II-III, with occasional class IV rapids depending on the water level.
The river run is divided into three segments: the upper, middle, and lower sections. The upper section is approximately 19 miles and runs from the West Fork of the Madison River to McAtee Bridge. It is known for its scenic views and technical rapids such as the Kitchen Sink and Ennis Falls. The middle section is 21 miles and runs from McAtee Bridge to Warm Springs. It is characterized by boulder-strewn rapids and waves, including the famous "Brennan's Wave" near Bozeman. The lower section is 22 miles and runs from Warm Springs to Three Forks. It is a calmer segment with occasional rapids and stunning views of the surrounding canyon.
Specific regulations to the area include a fishing closure from the Madison Dam to Ennis Lake during the months of March and April to protect spawning rainbow trout. Boaters are required to have a permit for commercial trips and are limited to a maximum of 24 passengers per day. Additionally, there is a 5-mile per hour speed limit for motorized boats on the river.
