Where SNAKE RIVER AT NYSSA OR sits, with 1 other gauge on the same river.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer: the trout lines Idaho Fish and Game uses are 66°F and 73°F.

Normal for Nov 5: 8,680–12,500 ft³/s (middle half of 48 years of record). Now: 7,230 ft³/s, lowest for this date on record.
Lowest for this date on record for this date. 7,230 ft³/s is below the lowest daily mean recorded on this date of daily mean flow for Nov 5 at this gauge over 48 years of record (1976–2026): 10th 8,260, 25th 8,680, median 9,570, 75th 12,500, 90th 15,000 ft³/s.
Daily means on record for Nov 5: lowest 7,890 ft³/s, highest 25,000 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 (+0.7% 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.
