Map of USGS gauge 01438500 and the river around it
Where Delaware River at Montague NJ sits, with 5 other gauges on the same river.
Normal for Nov 5: 1,930–5,400 ft³/s (middle half of 87 years of record). Now: 1,810 ft³/s, below normal.
Below normal for this date. 1,810 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 87 years of record (1940–2026): 10th 1,620, 25th 1,930, median 3,000, 75th 5,400, 90th 9,260 ft³/s.
Daily means on record for Nov 5: lowest 623 ft³/s, highest 17,600 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 (−7.7% 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 54.1°F now; the highest in the last 24 hours was 54.1°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 54.1°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, 9:45 PM EST; 7-day range 10.4–12.8 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 7.6 at Nov 5, 9:45 PM EST; 7-day range 7.4–8.6
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)Turbidity 0.7 FNU at Nov 5, 9:45 PM EST; 7-day range 0.6–2.7 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 123 µS/cm at Nov 5, 9:45 PM EST; 7-day range 116–127 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 5.13 ft stage, 1,760 ft³/s at Nov 5, 9:45 PM EST (NWS gauge MTGN4; its stage datum can differ from the USGS gauge height).
NWS river forecast forecast issued Nov 5, 10:15 AM EST. Highest point: 5.2 ft, 1,880 ft³/s on Nov 5, 1:00 PM EST (Below NWS action stage).
| Day | Stage | Flow |
|---|---|---|
| Thu, Nov 5 | 5.2 ft | 1,880 ft³/s |
| Fri, Nov 6 | 5.1 ft | 1,710 ft³/s |
| Sat, Nov 7 | 5 ft | 1,550 ft³/s |
