Map of USGS gauge 01402000 and the river around it
Where Millstone River at Blackwells Mills NJ sits, with 3 other gauges on the same river.
Federal guidance. New Jersey Fish and Wildlife publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a New Jersey rule, with New Jersey Fish and Wildlife's own figure added:
Normal for Nov 5: 86–291 ft³/s (middle half of 105 years of record). Now: 112 ft³/s, normal.
Normal for this date. 112 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 105 years of record (1922–2026): 10th 66, 25th 86, median 159, 75th 291, 90th 449 ft³/s.
Daily means on record for Nov 5: lowest 24 ft³/s, highest 1,340 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 (+1.8% 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.
Under the federal 68°F line. Water 60.8°F now; the highest in the last 24 hours was 60.8°F. That is under the 68°F at which the National Park Service, at Grand Teton National Park, recommends anglers stop fishing in the afternoon (“cease fishing at 2 p.m. when water temperatures are likely to exceed 68°F”). Water warms through the afternoon, so check again later in the day: “Carry a pocket thermometer to monitor water temperature.”
High water temperatures prompt fishing advisory in Grand Teton National Park (29 July 2022) (National Park Service)Species list not on file for this gauge. Check the New Jersey Fish & Wildlife: New Jersey trout stocking · New Jersey freshwater fishing regulations.
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)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 5.7 mg/L at Nov 5, 8:15 PM EST; 7-day range 5.7–8.1 mg/L
Below EPA's coldwater mean: 5.7 mg/L is under the 6.5 mg/L 30-day mean EPA sets for coldwater fish (other life stages), though above its 4 mg/L minimum. One reading is not a 30-day mean. Wyoming Game and Fish: “Higher water temperatures lead to lower oxygen levels.”
Quality Criteria for Water 1986 (“Gold Book”): dissolved oxygen, Table 1; pH (U.S. Environmental Protection Agency) Anglers encouraged to adjust fishing practices as temperatures rise (Wyoming Game and Fish Department)pH 7.2 at Nov 5, 8:15 PM EST; 7-day range 7.2–7.5
Within EPA's freshwater range: pH 7.2 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 2.4 FNU at Nov 5, 8:15 PM EST; 7-day range 2.1–6.4 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 462 µS/cm at Nov 5, 8:15 PM EST; 7-day range 385–481 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 1.74 ft stage, 112 ft³/s at Nov 5, 8:15 PM EST (NWS gauge BKWN4; its stage datum can differ from the USGS gauge height).
NWS river forecast forecast issued Nov 5, 10:18 AM EST. Highest point: 2.2 ft, 287 ft³/s on Nov 6, 1:00 PM EST (Below NWS action stage).
| Day | Stage | Flow |
|---|---|---|
| Thu, Nov 5 | 1.7 ft | 101 ft³/s |
| Fri, Nov 6 | 2.2 ft | 287 ft³/s |
| Sat, Nov 7 | 2.2 ft | 287 ft³/s |
| Sun, Nov 8 | 1.7 ft | 101 ft³/s |
