Map of USGS gauge 01206900 and the river around it
Where NAUGATUCK RIVER AT THOMASTON, 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: 42–160 ft³/s (middle half of 66 years of record). Now: 37.2 ft³/s, below normal.
Below normal for this date. 37.2 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 66 years of record (1961–2026): 10th 28, 25th 42, median 114, 75th 160, 90th 233 ft³/s.
Daily means on record for Nov 5: lowest 12.7 ft³/s, highest 1,240 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).
Rising over 24 hours: discharge up 11%, from 33.5 to 37.2 ft³/s. 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.
Rising water. Rising over the last 24 hours (discharge up 11%). Keep your way back to the bank in sight and watch the level while you fish. “Rising” is our rule of thumb: more than 10% in discharge or 0.2 ft of gauge height in 24 hours, not a USGS or NWS class.
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.
Turn Around Don't Drown (National Weather Service)Guidance from the readings above and the published thresholds named with each line; not a fishing forecast, a safety guarantee or a statement about access. Local rules and closures come first.
The National Weather Service has no flood-stage gauge here, so no official flood category is shown.
Checked Nov 5, 11:18 PM EST; readings refresh at most every 15 minutes and statistics daily. Provisional USGS data can be revised. Conditions change: re-check before you go. This is general guidance, not a fishing forecast, a safety guarantee or a statement about access.
