Map of USGS gauge 01407290 and the river around it
Where Big Brook near Marlboro NJ sits.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer. 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: 68°F and 72°F.

Normal for Nov 5: 4.5–9 ft³/s (middle half of 23 years of record). Now: 7.59 ft³/s, normal.
Normal for this date. 7.59 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 23 years of record (2004–2026): 10th 3.9, 25th 4.5, median 6.4, 75th 9, 90th 21 ft³/s.
Daily means on record for Nov 5: lowest 3.55 ft³/s, highest 23 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.
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.
