What RiverFinn tracks here
The sources, not today's numbers — those live in the app, with their observation times. This is what exists for the stretch, what does not, and where each figure comes from so you can check it yourself.
Measured by a thermometer on the water (USGS), with its own observation time. Never estimated from the weather.
Official source ↗A dam or spring sets the flow here, so RiverFinn does not compare it with a natural seasonal normal.
Checked automatically from Montana Fish, Wildlife & Parks's published notices several times a day and mapped to this reach.
Official source ↗General state regulations apply; always confirm with Montana Fish, Wildlife & Parks.
Official source ↗Fish Madison — Beartrap Canyon with the facts.
