Normal for Nov 5: 189–334 ft³/s (middle half of 89 years of record). Now: 66.4 ft³/s, much below normal.
Much below normal for this date. 66.4 ft³/s is below the 10th percentile of daily mean flow for Nov 5 at this gauge over 89 years of record: 10th 145, 25th 189, median 270, 75th 334, 90th 413 ft³/s.
Daily means on record for Nov 5: lowest 14 ft³/s, highest 1,110 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 (+1.5% 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.
