Map of USGS gauge 01188090 and the river around it
Where FARMINGTON RIVER AT UNIONVILLE, 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: 304–711 ft³/s (middle half of 49 years of record). Now: 272 ft³/s, below normal.
Below normal for this date. 272 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 49 years of record (1978–2026): 10th 221, 25th 304, median 469, 75th 711, 90th 1,090 ft³/s.
Daily means on record for Nov 5: lowest 106 ft³/s, highest 2,300 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).
Falling over 24 hours: discharge down 10.2%, from 303 to 272 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.
