Normal for Nov 5: 25–35 ft³/s (middle half of 75 years of record). Now: 26.9 ft³/s, normal.
Normal for this date. 26.9 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 75 years of record (1952–2026): 10th 22, 25th 25, median 30, 75th 35, 90th 41 ft³/s.
Daily means on record for Nov 5: lowest 15 ft³/s, highest 55 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 (−8.2% 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.
