Map of USGS gauge 06111800 and the river around it
Where Big Spring Cr at R&B Trading Post nr Lewistown MT 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 Big Spring Creek, but no agency page we read lists its species.
Not ranked: USGS has fewer than 10 years of daily flows for this date here.
Steady over 24 hours (−1.3% 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.
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.
Turn Around Don't Drown (National Weather Service)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.
NWS observed 3.75 ft stage at Nov 5, 7:30 PM MST (NWS gauge LTPM8; its stage datum can differ from the USGS gauge height).
