Map of USGS gauge 06178000 and the river around it
Where Poplar River at international boundary sits and our water's map point.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer: the trout lines Montana FWP uses are 66°F, 68°F and 73°F.
This gauge is on our page for Poplar River, but no agency page we read lists its species.
Not compared with the record because the reading is old.

Flood categories: action stage, minor, moderate and major flooding (National Weather Service)Turn Around Don't Drown. “A mere 6 inches of fast-moving flood water can knock over an adult.” No flow number makes a crossing safe; if in doubt, stay out.
