Map of USGS gauge 06101500 and the river around it
Where Marias River near Chester MT sits, with 1 other gauge on the same river 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 Marias River, but no agency page we read lists its species.
Normal for Nov 5: 367–692 ft³/s (middle half of 73 years of record). Now: 515 ft³/s, normal.
Normal for this date. 515 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 73 years of record: 10th 252, 25th 367, median 518, 75th 692, 90th 1,062 ft³/s.
Daily means on record for Nov 5: lowest 0.2 ft³/s, highest 2,020 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 (+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.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
