Map of USGS gauge 03010820 and the river around it
Where ALLEGHENY RIVER AT OLEAN NY sits, with 4 other gauges on the same river and our water's map point.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer: the trout lines New York DEC uses are 70°F.
Normal for Nov 5: 655–2,820 ft³/s (middle half of 16 years of record). Now: 375 ft³/s, much below normal.
Much below normal for this date. 375 ft³/s is below the 10th percentile of daily mean flow for Nov 5 at this gauge over 16 years of record (2011–2026): 10th 379, 25th 655, median 1,590, 75th 2,820, 90th 4,700 ft³/s.
Daily means on record for Nov 5: lowest 370 ft³/s, highest 5,060 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).
Falling over 24 hours: discharge down 19.2%, from 464 to 375 ft³/s. 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.
