Map of USGS gauge 01154950 and the river around it
Where COLD RIVER AT HIGH STREET, AT ALSTEAD, NH sits and our water's map point.
Federal guidance. New Hampshire Fish and Game Department publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a New Hampshire rule:
Under the federal 68°F line. Water 52°F now; the highest in the last 24 hours was 52°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: 31–131 ft³/s (middle half of 17 years of record). Now: 18.1 ft³/s, much below normal.
Much below normal for this date. 18.1 ft³/s is below the 10th percentile of daily mean flow for Nov 5 at this gauge over 17 years of record (2010–2026): 10th 22, 25th 31, median 76, 75th 131, 90th 427 ft³/s.
Daily means on record for Nov 5: lowest 12.4 ft³/s, highest 523 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 19.1%, from 15.2 to 18.1 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 the same river as our page for Cold River, but no agency page we read lists its species.
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)Rising water. Rising over the last 24 hours (discharge up 19.1%). 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 52°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)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 1.73 ft stage, 18 ft³/s at Nov 5, 8:45 PM EST (NWS gauge ASTN3; its stage datum can differ from the USGS gauge height).

Checked Nov 5, 9:40 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.
