Map of USGS gauge 01553500 and the river around it
Where West Branch Susquehanna River at Lewisburg, PA 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 Pennsylvania Fish and Boat Commission uses are 60°F, 70°F and 72°F.
Normal for Nov 5: 2,070–9,530 ft³/s (middle half of 86 years of record). Now: 2,430 ft³/s, normal.
Normal for this date. 2,430 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 86 years of record (1940–2025): 10th 1,360, 25th 2,070, median 4,500, 75th 9,530, 90th 16,800 ft³/s.
Daily means on record for Nov 5: lowest 588 ft³/s, highest 29,300 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 (+5.2% 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.
