Diamond River near Wentworth Location, NH

USGS 01052500 · NWS DIAN3

No gauge on Dead Diamond River. Nearest: Diamond River near Wentworth Location, NH (4.6 mi away), on the river it flows into. Dead Diamond River's own flow is not measured.

Caution: Low water: go quiet and stealthy

Flow 64.5 ft³/s: much below normal (under the 10th percentile) for Nov 5, over 85 years of USGS record. U.S. Geological Survey
Rising: discharge up 13.4% in 24 hours (56.9 to 64.5 ft³/s). Our rule of thumb: more than 10% (or 0.2 ft) in 24 hours, not a USGS class.

What the agencies suggest

Stay low and approach slowly. Approach the stream carefully and with a low profile Iowa Department of Natural Resources
Work upstream. Fishing upstream will usually spook fewer fish than working downstream Iowa Department of Natural Resources
Look to deep pools and undercut banks. Deep pools and undercut banks provide refuge during sunny days and low water Minnesota Department of Natural Resources

General guidance from the readings and the published lines named above, not a fishing forecast. Local rules and closures come first.

What this level means general guidance

Normal for Nov 5: 174–489 ft³/s (middle half of 85 years of record). Now: 64.5 ft³/s, much below normal.

Much below normal for this date. 64.5 ft³/s is below the 10th percentile of daily mean flow for Nov 5 at this gauge over 85 years of record (1942–2026): 10th 108, 25th 174, median 267, 75th 489, 90th 728 ft³/s.

Daily means on record for Nov 5: lowest 54 ft³/s, highest 1,350 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 13.4%, from 56.9 to 64.5 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.

Official flood stage · National Weather Service

NWS observed 2.09 ft stage, 63 ft³/s at Nov 5, 5:15 PM EST (NWS gauge DIAN3; its stage datum can differ from the USGS gauge height).

NWS has not set flood categories for this gauge.

Conditions for fishing general guidance

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.

Species

This gauge is on our page for Dead Diamond River, but no agency page we read lists its species.

Safety

Rising water. Rising over the last 24 hours (discharge up 13.4%). 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)

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.

Follow Dead Diamond River for flow alerts

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.

Follow this water

Signed in: one step. Otherwise we email a confirmation link first. Every alert has one-click links to stop it.

Where to fish

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.

Position: a point on the mapped channel of “Dead Diamond River”, halfway along its length in New Hampshire, from the USGS high-resolution hydrography (NHDPlus HR), read 4 Nov 2026.

Diamond River near Wentworth Location, NH

USGS 01052500 · NWS DIAN3

No gauge on Dead Diamond River. Nearest: Diamond River near Wentworth Location, NH (4.6 mi away), on the river it flows into. Dead Diamond River's own flow is not measured.

Caution: Low water: go quiet and stealthy

Flow 64.5 ft³/s: much below normal (under the 10th percentile) for Nov 5, over 85 years of USGS record. U.S. Geological Survey
Rising: discharge up 13.4% in 24 hours (56.9 to 64.5 ft³/s). Our rule of thumb: more than 10% (or 0.2 ft) in 24 hours, not a USGS class.

What the agencies suggest

Stay low and approach slowly. Approach the stream carefully and with a low profile Iowa Department of Natural Resources
Work upstream. Fishing upstream will usually spook fewer fish than working downstream Iowa Department of Natural Resources
Look to deep pools and undercut banks. Deep pools and undercut banks provide refuge during sunny days and low water Minnesota Department of Natural Resources

Conditions for fishing general guidance

Species

This gauge is on our page for Dead Diamond River, but no agency page we read lists its species.

Safety

Rising water. Rising over the last 24 hours (discharge up 13.4%). 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.
