The Lamprey River is a tailwater in New Hampshire, listed as Catch and release by New Hampshire Fish and Game Department (official eRegulations edition of the Freshwater Fishing Digest).
2 USGS gauges on the water report flow.
Lamprey River is a tailwater in New Hampshire.
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.

Seasons, limits, special regulations and closures for each reach are on the agency pages below. Read them before you go.
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.

Areas the Protected Areas Database of the United States (PAD-US), public access (U.S. Geological Survey, Gap Analysis Project, read 2026-11-05) lists as owned or held in easement and open to the public, crossed by the mapped channel.

A water page organises discovery. It does not assert public access, legal access, current fish presence, guide availability or fishing conditions.
Flows, gauge statistics and flood stages come from USGS and the National Weather Service when the page is shown.

Normal for Nov 5: 14–75 ft³/s (middle half of 18 years of record). Now: 9.95 ft³/s, below normal.
Below normal for this date. 9.95 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 18 years of record (2009–2026): 10th 8.4, 25th 14, median 32, 75th 75, 90th 207 ft³/s.
Daily means on record for Nov 5: lowest 5.12 ft³/s, highest 430 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 11.2%, from 11.2 to 9.95 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.
NWS observed 1.92 ft stage, 11 ft³/s at Nov 5, 2:45 PM EST (NWS gauge RAYN3; its stage datum can differ from the USGS gauge height).
NWS has not set flood categories for this gauge.

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 50.2°F now; the highest in the last 24 hours was 50.9°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.”
High water temperatures prompt fishing advisory in Grand Teton National Park (29 July 2022) (National Park Service)This gauge is on our page for Lamprey River, but no agency page we read lists its species.
Cold water. Water 50.2°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.

Normal for Nov 5: 83–289 ft³/s (middle half of 92 years of record). Now: 85.7 ft³/s, normal.
Normal for this date. 85.7 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 92 years of record (1935–2026): 10th 56, 25th 83, median 141, 75th 289, 90th 577 ft³/s.
Daily means on record for Nov 5: lowest 8.6 ft³/s, highest 1,960 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 (+0% 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.
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 1.52 ft stage, 86 ft³/s at Nov 5, 3:15 PM EST (NWS gauge LAMN3; its stage datum can differ from the USGS gauge height).
Forecasts are issued as needed during times of high water, but are not routinely available.
