No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer. New Hampshire Fish and Game Department 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 Hampshire rule: 68°F.

Normal for Nov 5: 98–267 ft³/s (middle half of 87 years of record). Now: 53 ft³/s, much below normal.
Much below normal for this date. 53 ft³/s is below the 10th percentile of daily mean flow for Nov 5 at this gauge over 87 years of record (1940–2026): 10th 73, 25th 98, median 168, 75th 267, 90th 394 ft³/s.
Daily means on record for Nov 5: lowest 30 ft³/s, highest 1,010 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 (+3.5% 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.
