Map of USGS gauge 12301250 and the river around it
Where Tobacco River at Eureka, 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 Tobacco River, but no agency page we read lists its species.
Normal for Nov 5: 87–180 ft³/s (middle half of 10 years of record). Now: 84.5 ft³/s, below normal.
Below normal for this date. 84.5 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 10 years of record (2017–2026): 10th 76, 25th 87, median 119, 75th 180, 90th 304 ft³/s.
Daily means on record for Nov 5: lowest 75.9 ft³/s, highest 316 ft³/s.
Classes as USGS labels them (hyswap: flow categories (WDFN_stats schema) (U.S. Geological Survey) ); percentiles from the USGS daily statistics (U.S. Geological Survey) (approved daily means; the reading is provisional and instantaneous).
Steady over 24 hours (+2.3% 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.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
