Montana River Flow Rates & Stream Gauge Data
Live USGS stream gauge data for Montana — current CFS flow rates, gauge heights, water temperatures, and wading conditions for Montana rivers and streams. Updated every 15 minutes. Know before you go.
Planning with Montana river conditions
Browse USGS monitoring stations across Montana rivers and streams. Each gauge page
shows current readings plus 7, 14, and 30-day flow-rate charts with condition indicators.
Compare the station name and location with your intended reach, then use the recent trend
alongside the current reading. Rain, snowmelt, dams, tributaries, and the distance between
stations can produce different conditions on the same river.
Montana river guides Madison River — The Madison River is a classic Montana trout destination, extending from high-elevation water near West Yellowstone through broad valley and tailwater reaches.Gallatin River — The Gallatin River is a varied Montana trout river with mapped reaches from canyon water through the valley. Its gauges help separate local conditions from broader regional weather.Yellowstone River — The Yellowstone is a large Montana river where current, seasonal runoff, and access logistics shape the fishing day. Use the gauges to understand the river before choosing a section.Rock Creek — Montana's Rock Creek is a smaller, scenic trout river with abundant mapped water. Its many tributary and fork names make a map check useful when planning a specific access point.Plan seasonal fly selection with the Montana hatch chart .
