Map of USGS gauge 01554000 and the river around it
Where Susquehanna River at Sunbury, PA sits, with 3 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: 6,360–27,300 ft³/s (middle half of 89 years of record). Now: 5,660 ft³/s, below normal.
Below normal for this date. 5,660 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 89 years of record (1938–2026): 10th 3,520, 25th 6,360, median 12,600, 75th 27,300, 90th 41,100 ft³/s.
Daily means on record for Nov 5: lowest 1,460 ft³/s, highest 80,800 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 24.8%, from 7,530 to 5,660 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.
This gauge is on the same river as our page for Susquehanna River, but no agency page we read lists its species.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
Flood categories: action stage, minor, moderate and major flooding (National Weather Service)Turn Around Don't Drown. “A mere 6 inches of fast-moving flood water can knock over an adult.” No flow number makes a crossing safe; if in doubt, stay out.
Turn Around Don't Drown (National Weather Service)Guidance from the readings above and the published thresholds named with each line; not a fishing forecast, a safety guarantee or a statement about access. Local rules and closures come first.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
NWS observed 6.59 ft stage, 5,660 ft³/s at Nov 5, 8:45 PM EST (NWS gauge SBYP1; its stage datum can differ from the USGS gauge height).
