Map of USGS gauge 01193050 and the river around it
Where CONNECTICUT RIVER AT MIDDLE HADDAM, CT sits, with 1 other gauge 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 55.6°F now; the highest in the last 24 hours was 55.6°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.”
USGS publishes no daily statistics for this gauge, so the reading is not compared with the record.
Rising over 24 hours: discharge up 64.5%, from 760 to 1,250 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.
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.
Rising water. Rising over the last 24 hours (discharge up 64.5%). 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.
Cold water. Water 55.6°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 10.3 mg/L at Nov 5, 10:15 PM EST; 7-day range 10–10.6 mg/L
Enough oxygen for coldwater fish: 10.3 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, 10:15 PM EST; 7-day range 7.3–7.5
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 1.8 FNU at Nov 5, 10:15 PM EST; 7-day range 1.5–2.6 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 229 µS/cm at Nov 5, 10:15 PM EST; 7-day range 222–241 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.
NWS observation not current. NWS has no current observation at this gauge, so no flood category is shown.
