Map of USGS gauge 01184000 and the river around it
Where CONNECTICUT RIVER AT THOMPSONVILLE, CT sits, with 2 other gauges on the same river.
Federal guidance. 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:
Under the federal 68°F line. Water 56.1°F now; the highest in the last 24 hours was 56.1°F. That is under the 68°F at which the National Park Service, at Grand Teton National Park, recommends anglers stop fishing in the afternoon (“cease fishing at 2 p.m. when water temperatures are likely to exceed 68°F”). Water warms through the afternoon, so check again later in the day: “Carry a pocket thermometer to monitor water temperature.”
Normal for Nov 5: 6,750–19,900 ft³/s (middle half of 98 years of record). Now: 4,290 ft³/s, much below normal.
Much below normal for this date. 4,290 ft³/s is below the 10th percentile of daily mean flow for Nov 5 at this gauge over 98 years of record (1929–2026): 10th 4,710, 25th 6,750, median 11,800, 75th 19,900, 90th 26,500 ft³/s.
Daily means on record for Nov 5: lowest 1,720 ft³/s, highest 72,300 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).
Steady over 24 hours (+9.2% 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.
Species list not on file for this gauge. Check the Connecticut Department of Energy and Environmental Protection (DEEP): Connecticut trout stocking maps · Connecticut freshwater fishing regulations.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
Flood categories: action stage, minor, moderate and major flooding (National Weather Service)Cold water. Water 56.1°F. NWS: “Cold shock can be just as severe and dangerous from water temperatures of 50-60°F (10-15°C) as it is from water at 35°F (2°C).” “Always wear a life jacket in and around the water.”
Cold Water Hazards and Safety (National Weather Service)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)Dissolved oxygen 10.1 mg/L at Nov 5, 11:00 PM EST; 7-day range 10.1–12 mg/L
Enough oxygen for coldwater fish: 10.1 mg/L meets the 6.5 mg/L EPA sets for coldwater fish (other life stages; eggs and fry need a 8 mg/L minimum).
Quality Criteria for Water 1986 (“Gold Book”): dissolved oxygen, Table 1; pH (U.S. Environmental Protection Agency)pH 7.4 at Nov 5, 11:00 PM EST; 7-day range 7.3–7.8
Within EPA's freshwater range: pH 7.4 is within the 6.5–9 range EPA gives for freshwater aquatic life.
Quality Criteria for Water 1986 (“Gold Book”): dissolved oxygen, Table 1; pH (U.S. Environmental Protection Agency)Turbidity 2.7 FNU at Nov 5, 11:00 PM EST; 7-day range 2.1–3.4 FNU
Water clarity: Turbidity measures the relative clarity of water: higher means murkier. No agency publishes a fishing threshold for it; compare with this gauge's own recent readings.
Turbidity and Water (U.S. Geological Survey)Specific conductance 194 µS/cm at Nov 5, 11:00 PM EST; 7-day range 187–202 µS/cm
Dissolved ions: Specific conductance rises with the ions dissolved in the water. No fishing threshold is published for it; compare with this gauge's own recent readings.
Conductivity (Electrical Conductance) and Water (U.S. Geological Survey)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.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
NWS observed 7.83 ft stage at Nov 5, 10:30 PM EST (NWS gauge TMVC3; its stage datum can differ from the USGS gauge height).
NWS river forecast forecast issued Nov 5, 10:32 AM EST. Highest point: 7.9 ft on Nov 7, 7:00 AM EST (Below NWS action stage).
| Day | Stage | Flow |

| Thu, Nov 5 | 7.7 ft | – |
| Fri, Nov 6 | 7.8 ft | – |
| Sat, Nov 7 | 7.9 ft | – |
| Sun, Nov 8 | 7.9 ft | – |
