Normal for Nov 5: 376–1,100 ft³/s (middle half of 56 years of record). Now: 415 ft³/s, normal.
Normal for this date. 415 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 56 years of record (1971–2026): 10th 288, 25th 376, median 503, 75th 1,100, 90th 1,900 ft³/s.
Daily means on record for Nov 5: lowest 60 ft³/s, highest 2,770 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 (+4.5% 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.
