Map of USGS gauge 01542500 and the river around it
Where WB Susquehanna River at Karthaus, PA sits, with 3 other gauges on the same river and our water's map point.
Normal for Nov 5: 484–1,700 ft³/s (middle half of 53 years of record). Now: 809 ft³/s, normal.
Normal for this date. 809 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 53 years of record (1961–2026): 10th 365, 25th 484, median 1,040, 75th 1,700, 90th 2,690 ft³/s.
Daily means on record for Nov 5: lowest 163 ft³/s, highest 7,200 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 14.3%, from 708 to 809 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.
In or under PFBC's preferred range. Water 57.7°F now; the highest in the last 24 hours was 59°F. The Pennsylvania Fish and Boat Commission: “The preferred temperature range for trout is between 50 and 60 degrees Fahrenheit.”

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 14.3%). 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.
Cold water. Water 57.7°F. NWS: “Cold shock can be just as severe and dangerous from water temperatures of 50-60°F (10-15°C) as it is from water at 35°F (2°C).” “Always wear a life jacket in and around the water.”
Cold Water Hazards and Safety (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)Dissolved oxygen 10 mg/L at Nov 1, 12:45 AM EDT; 7-day range 9.3–10.5 mg/L; more than a day old
Enough oxygen for coldwater fish: 10 mg/L meets the 6.5 mg/L EPA sets for coldwater fish (other life stages; eggs and fry need a 8 mg/L minimum).
Quality Criteria for Water 1986 (“Gold Book”): dissolved oxygen, Table 1; pH (U.S. Environmental Protection Agency)pH 7.6 at Nov 1, 12:45 AM EDT; 7-day range 7.5–7.6; more than a day old
Within EPA's freshwater range: pH 7.6 is within the 6.5–9 range EPA gives for freshwater aquatic life.
Quality Criteria for Water 1986 (“Gold Book”): dissolved oxygen, Table 1; pH (U.S. Environmental Protection Agency)Specific conductance 406 µS/cm at Nov 5, 9:30 PM EST; 7-day range 365–406 µS/cm
Dissolved ions: Specific conductance rises with the ions dissolved in the water. No fishing threshold is published for it; compare with this gauge's own recent readings.

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 1.99 ft stage, 809 ft³/s at Nov 5, 8:30 PM EST (NWS gauge KARP1; its stage datum can differ from the USGS gauge height).
NWS river forecast forecast issued Nov 5, 9:45 AM EST. Highest point: 2 ft, 818 ft³/s on Nov 5, 1:00 PM EST (Below NWS action stage).
