The Madison River runs 140 miles from Yellowstone National Park to Three Forks, Montana. We monitor two distinct sections:
- Upper Madison:
Hebgen Dam to Ennis Lake. Cold, clear freestone water with rainbow and brown trout. Home to the famous salmonfly hatch in late June.
- Lower Madison:
Ennis Dam tailwater to Three Forks. Colder flows create a different fishery with earlier hatches and year-round fishing opportunities.
Each report pulls real-time data from USGS gauges and combines it with weather conditions, historical patterns, and seasonal hatch information. Our AI analysis generates specific fly recommendations based on current conditions.
Check the reports daily before your trip. Conditions on the Madison can change quickly with weather fronts, dam releases, and seasonal transitions.
