Nashua River is a freestone river in New Hampshire and Massachusetts.
Pick one of its USGS gauges and hear from us when the flow moves into or out of its usual range for the date, or crosses a flow you set. We check the public USGS reading every 2 hours and email only when it crosses, at most once every 6 hours. Flow alone is not a fishing forecast or a safety call.
Signed in: one step. Otherwise we email a confirmation link first. Every alert has one-click links to stop it.
Start from the agency's public access map. Nothing on this page grants or implies access: check the agency map, posted signs and landowner permission before you fish.

Each comes from the agency's own published list; where the list names a reach it is quoted. A designation applies to the listed reach, not necessarily the whole water. Listed in the finder under trout.

Normal for Nov 5: 179–537 ft³/s (middle half of 91 years of record). Now: 276 ft³/s, normal.
Normal for this date. 276 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 91 years of record (1936–2026): 10th 95, 25th 179, median 325, 75th 537, 90th 922 ft³/s.
Daily means on record for Nov 5: lowest 5.4 ft³/s, highest 3,620 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 50.8%, from 183 to 276 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.
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 1.6 ft stage, 276 ft³/s at Nov 5, 5:45 PM EST (NWS gauge DNSM3; its stage datum can differ from the USGS gauge height).

Flood categories: action stage, minor, moderate and major flooding (National Weather Service)Rising water. Rising over the last 24 hours (discharge up 50.8%). 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.

Normal for Nov 5: 3,080–8,260 ft³/s (middle half of 103 years of record). Now: 2,450 ft³/s, below normal.
Below normal for this date. 2,450 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 103 years of record (1924–2026): 10th 1,870, 25th 3,080, median 4,430, 75th 8,260, 90th 15,200 ft³/s.
Daily means on record for Nov 5: lowest 444 ft³/s, highest 66,200 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 15%, from 2,130 to 2,450 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.
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 42.2 ft stage, 2,440 ft³/s at Nov 5, 5:30 PM EST (NWS gauge LOWM3; its stage datum can differ from the USGS gauge height).
NWS river forecast forecast issued Nov 5, 10:32 AM EST. Highest point: 42.2 ft, 2,350 ft³/s on Nov 7, 1:00 AM EST (Below NWS action stage).
| Day | Stage | Flow |
|---|---|---|
| Thu, Nov 5 | 41.9 ft | 1,740 ft³/s |
| Fri, Nov 6 | 42.1 ft | 2,140 ft³/s |
| Sat, Nov 7 | 42.2 ft | 2,350 ft³/s |
| Sun, Nov 8 | 42.2 ft | 2,350 ft³/s |

No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer. 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: 68°F.
This gauge is on our page for Nashua 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 15%). 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.
Checked Nov 5, 6:20 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.
