Tongue River at Ashland, MT

USGS publishes no daily statistics for this gauge, so the reading is not compared with the record.

Steady over 24 hours (+0% discharge). Rising or falling means a change of more than 10% in discharge (or 0.2 ft of gauge height) over 24 hours; our rule of thumb, not a USGS class.

This gauge is on our page for Tongue River, but no agency page we read lists its species.

Guidance from the readings above and the published thresholds named with each line; not a fishing forecast, a safety guarantee or a statement about access. Local rules and closures come first.
