Map of USGS gauge 01576000 and the river around it
Where Susquehanna River at Marietta, PA sits, with 5 other gauges on the same river.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer: the trout lines Pennsylvania Fish and Boat Commission uses are 60°F, 70°F and 72°F.
Normal for Nov 5: 8,430–33,800 ft³/s (middle half of 95 years of record). Now: 10,700 ft³/s, normal.
Normal for this date. 10,700 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 95 years of record (1932–2026): 10th 5,120, 25th 8,430, median 19,400, 75th 33,800, 90th 53,600 ft³/s.
Daily means on record for Nov 5: lowest 2,410 ft³/s, highest 102,000 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 (−0.9% 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.
