Map of USGS gauge 01208500 and the river around it
Where NAUGATUCK RIVER AT BEACON FALLS, CT 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. Connecticut DEEP publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a Connecticut rule, with Connecticut DEEP's own figure added: 68°F.
Normal for Nov 5: 140–480 ft³/s (middle half of 98 years of record). Now: 153 ft³/s, normal.
Normal for this date. 153 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 98 years of record (1929–2026): 10th 99, 25th 140, median 282, 75th 480, 90th 740 ft³/s.
Daily means on record for Nov 5: lowest 64 ft³/s, highest 8,100 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 (+1.3% 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 Naugatuck River, but no agency page we read lists its species.
