Map of USGS gauge 01578310 and the river around it
Where SUSQUEHANNA RIVER AT CONOWINGO, MD sits, with 4 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 Maryland DNR uses are 65°F and 68°F.
Normal for Nov 5: 10,400–42,200 ft³/s (middle half of 59 years of record). Now: 12,300 ft³/s, normal.
Normal for this date. 12,300 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 59 years of record (1968–2026): 10th 4,710, 25th 10,400, median 23,400, 75th 42,200, 90th 69,100 ft³/s.
Daily means on record for Nov 5: lowest 965 ft³/s, highest 91,900 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).
Rising over 24 hours: discharge up 55.3%, from 7,920 to 12,300 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.

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)Rising water. Rising over the last 24 hours (discharge up 55.3%). Keep your way back to the bank in sight and watch the level while you fish. “Rising” is our rule of thumb: more than 10% in discharge or 0.2 ft of gauge height in 24 hours, not a USGS or NWS class.
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.
