Normal for Nov 5: 66–98 ft³/s (middle half of 108 years of record). Now: 50.1 ft³/s, much below normal.
Much below normal for this date. 50.1 ft³/s is below the 10th percentile of daily mean flow for Nov 5 at this gauge over 108 years of record (1915–2026): 10th 52, 25th 66, median 81, 75th 98, 90th 126 ft³/s.
Daily means on record for Nov 5: lowest 44 ft³/s, highest 173 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 (−1.4% 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.
