Map of USGS gauge 01381400 and the river around it
Where Whippany River near Morristown NJ sits, with 2 other gauges on the same river and our water's map point.
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: 6.1–20 ft³/s (middle half of 28 years of record). Now: 8.04 ft³/s, normal.
Normal for this date. 8.04 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 28 years of record (1996–2023): 10th 5.1, 25th 6.1, median 11, 75th 20, 90th 28 ft³/s.
Daily means on record for Nov 5: lowest 4.76 ft³/s, highest 33.5 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.
This gauge is on our page for Whippany River, but no agency page we read lists its species.
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.
