Reading Nov 5, 9:15 PM EST · provisional USGS data
No flow at this gauge. USGS does not publish discharge here, so there are no flow statistics either; it reports what is shown. Flow on the same river: Susquehanna River at Marietta, PA (USGS 01576000, 1.9 miles away).
Water temperature, last 7 days: 169 readings from Oct 29, 10:15 PM EDT to Nov 5, 9:15 PM EST; ranging 55.8 to 60.8 °F; latest 60.8 °F.
USGS provisional data may be revised. Source: USGS instantaneous values.

Map of USGS gauge 01576003 and the river around it
Where Susquehanna River at Columbia, PA sits, with 5 other gauges on the same river.
Above the preferred range. Water 60.8°F now; the highest in the last 24 hours was 60.8°F. Warmer than the 50 to 60°F the Pennsylvania Fish and Boat Commission gives as preferred for trout, but not over the 70°F at which it asks anglers to take extra care landing them.

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 9.6 mg/L at Nov 5, 9:15 PM EST; 7-day range 9.6–12.3 mg/L
Enough oxygen for coldwater fish: 9.6 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 8.2 at Nov 5, 9:15 PM EST; 7-day range 8.2–8.9
Within EPA's freshwater range: pH 8.2 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)Turbidity 1.6 FNU at Nov 5, 9:15 PM EST; 7-day range 1–10.4 FNU
Water clarity: Turbidity measures the relative clarity of water: higher means murkier. No agency publishes a fishing threshold for it; compare with this gauge's own recent readings.
Turbidity and Water (U.S. Geological Survey)Specific conductance 401 µS/cm at Nov 5, 9:15 PM EST; 7-day range 358–420 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.
Conductivity (Electrical Conductance) and Water (U.S. Geological Survey)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.
The National Weather Service has no flood-stage gauge here, so no official flood category is shown.
Checked Nov 5, 9:54 PM EST; readings refresh at most every 15 minutes and statistics daily. Provisional USGS data can be revised. Conditions change: re-check before you go. This is general guidance, not a fishing forecast, a safety guarantee or a statement about access.
