Normal for Nov 5: 99–270 ft³/s (middle half of 87 years of record). Now: 319 ft³/s, above normal.
Above normal for this date. 319 ft³/s is between the 75th and 90th percentiles of daily mean flow for Nov 5 at this gauge over 87 years of record (1940–2026): 10th 73, 25th 99, median 171, 75th 270, 90th 422 ft³/s.
Daily means on record for Nov 5: lowest 41.6 ft³/s, highest 2,950 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 (+6% 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.
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.
Turn Around Don't Drown (National Weather Service)Dissolved oxygen 11.5 mg/L at Nov 1, 12:30 AM MDT; 7-day range 11.4–12.1 mg/L; more than a day old
Enough oxygen for coldwater fish: 11.5 mg/L meets the 6.5 mg/L EPA sets for coldwater fish (other life stages; eggs and fry need a 8 mg/L minimum).
Quality Criteria for Water 1986 (“Gold Book”): dissolved oxygen, Table 1; pH (U.S. Environmental Protection Agency)pH 8.4 at Nov 1, 12:30 AM MDT; 7-day range 8.4–8.4; more than a day old
Within EPA's freshwater range: pH 8.4 is within the 6.5–9 range EPA gives for freshwater aquatic life.
Quality Criteria for Water 1986 (“Gold Book”): dissolved oxygen, Table 1; pH (U.S. Environmental Protection Agency)Turbidity 21.3 FNU at Nov 1, 12:30 AM MDT; 7-day range 16.5–21.5 FNU; more than a day old
Water clarity: Turbidity measures the relative clarity of water: higher means murkier. No agency publishes a fishing threshold for it; compare with this gauge's own recent readings.
Turbidity and Water (U.S. Geological Survey)Specific conductance 1,160 µS/cm at Nov 1, 12:30 AM MDT; 7-day range 1,130–1,160 µS/cm; more than a day old
Dissolved ions: Specific conductance rises with the ions dissolved in the water. No fishing threshold is published for it; compare with this gauge's own recent readings.
Conductivity (Electrical Conductance) and Water (U.S. Geological Survey)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.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
NWS observed 2.33 ft stage, 315 ft³/s at Nov 5, 8:00 PM MST (NWS gauge NSHM8; its stage datum can differ from the USGS gauge height).
Forecasts are issued as needed during times of high water, but are not routinely available.
