Map of USGS gauge 01473500 and the river around it
Where Schuylkill River at Norristown, PA sits, with 5 other gauges on the same river and our water's map point.
Normal for Nov 5: 820–3,410 ft³/s (middle half of 31 years of record). Now: 893 ft³/s, normal.
Normal for this date. 893 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 31 years of record (1928–2026): 10th 515, 25th 820, median 1,460, 75th 3,410, 90th 5,670 ft³/s.
Daily means on record for Nov 5: lowest 358 ft³/s, highest 9,030 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 (+0% 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.
In or under PFBC's preferred range. Water 58.3°F now; the highest in the last 24 hours was 59.2°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)Cold water. Water 58.3°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 10.4 mg/L at Nov 5, 7:30 PM EST; 7-day range 9.9–12.3 mg/L
Enough oxygen for coldwater fish: 10.4 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 at Nov 5, 7:30 PM EST; 7-day range 7.8–8.4
Within EPA's freshwater range: pH 8 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 2 FNU at Nov 5, 7:30 PM EST; 7-day range 1.5–6.2 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 546 µS/cm at Nov 5, 7:30 PM EST; 7-day range 505–565 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.
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 7.96 ft stage, 886 ft³/s at Nov 5, 7:30 PM EST (NWS gauge NRSP1; its stage datum can differ from the USGS gauge height).
NWS river forecast forecast issued Nov 5, 10:17 AM EST. Highest point: 8.4 ft, 2,270 ft³/s on Nov 6, 7:00 AM EST (Below NWS action stage).
| Day | Stage | Flow |
|---|---|---|
| Thu, Nov 5 | 8 ft | 1,000 ft³/s |
| Fri, Nov 6 | 8.4 ft | 2,270 ft³/s |
| Sat, Nov 7 | 8.2 ft | 1,610 ft³/s |
| Sun, Nov 8 | 8 ft | 1,000 ft³/s |
