Map of USGS gauge 01398500 and the river around it
Where North Branch Raritan River near Far Hills NJ sits, with 3 other gauges on the same river.
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: 13–43 ft³/s (middle half of 103 years of record). Now: 19 ft³/s, normal.
Normal for this date. 19 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 103 years of record (1922–2026): 10th 8.4, 25th 13, median 24, 75th 43, 90th 65 ft³/s.
Daily means on record for Nov 5: lowest 4.5 ft³/s, highest 187 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 (+9.2% 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.
