Map of USGS gauge 01098530 and the river around it
Where SUDBURY RIVER AT SAXONVILLE, MA sits, with 1 other gauge on the same river.
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: 55–219 ft³/s (middle half of 47 years of record). Now: 89.1 ft³/s, normal.
Normal for this date. 89.1 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 47 years of record (1980–2026): 10th 29, 25th 55, median 100, 75th 219, 90th 335 ft³/s.
Daily means on record for Nov 5: lowest 9.18 ft³/s, highest 583 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.
