No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer. MassWildlife publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a Massachusetts rule: 68°F.

Normal for Nov 5: 206–642 ft³/s (middle half of 89 years of record). Now: 169 ft³/s, below normal.
Below normal for this date. 169 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 89 years of record (1938–2026): 10th 109, 25th 206, median 370, 75th 642, 90th 1,060 ft³/s.
Daily means on record for Nov 5: lowest 65 ft³/s, highest 1,900 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.
