Wade and Bank / edge have the same top score. Use current access, footing, weather, and local rules to choose.

Wade94/100

Wading is in play only where your chosen access has clear footing, legal entry, and no forced crossings.

Bank / edge94/100

Bank and edge fishing remains a practical low-commitment option if access is legal and footing is safe.

FloatNot recommended

This report does not recommend floating this reach.

Your plan

Today's Upper Connecticut River plan.

The Upper Connecticut near Pittsburg is one of New Hampshire's key northern coldwater rivers. Conditions, rules, and reach choice matter more than a generic statewide trout plan.

Check first
Check the below-Indian-Stream gauge before wading.
Try
Start at the below-Indian-Stream gauge and avoid wading heavy pocket water when flow is up.
Leave when
Skip or shorten the plan when the river is high or rising, cold storms are moving through, summer temperature checks are poor, or legal access and rule boundaries are not clear.

How to fish it

How to fish Upper Connecticut River today.

The best days have cold stable water and enough clarity to fish seams carefully. High flow, cold storms, or warm summer afternoons should change the plan quickly.

01

Cold and stable

Fish nymphs, soft hackles, small dries, and streamers through seams.

02

Higher flow

Focus on edges and pool margins. Avoid unsafe crossings.

03

Low clear water

Use longer leaders, smaller flies, and careful approaches.

04

Warm afternoon

Check temperature and stop trout handling when water is too warm.

Fishing words used on this page
U.S. Geological Survey (USGS) gauge
A USGS gauge is an official river station that measures flow or water height.
Cubic feet per second (cfs)
Cubic feet per second, or cfs, shows how much water passes the gauge each second.
Nymph
A nymph is a young water insect. Anglers also use the word for a fly that copies it.
Seam
A seam is the line where fast and slow water meet.
Tailout
A tailout is the shallow, slower water at the lower end of a pool.
Blue-winged olive (BWO)
Blue-winged olives, or BWOs, are small mayflies that often hatch in cool or cloudy weather.
Caddis
Caddis are small water insects. The adults look a little like tiny moths.
Emerger
An emerger copies an insect as it rises from below the water toward the surface.
Midge
Midges are tiny flies and a common trout food, especially in cold water.
Pocket water
Pocket water is a small calm spot among rocks or fast current.
Why this call

Why this score

FlowHelps

USGS shows 324 cfs. The flow has been stable over about 6 hours. USGS marks this reading provisional and may revise it. USGS records for this date (1957-2025, 69 readings) show a typical middle range of 307 cfs to 637 cfs. Flow is within the typical range for this date, so weather, temperature, and access become the next checks.

SeasonHelps

Summer: Mornings, shade, terrestrials, and temperature checks.

Water temperatureHelps

USGS water temperature is about 61.2F, and the rolling 24-hour high did not trigger a heat caution. USGS marks the temperature data provisional and may revise it.

Public alertsHelps

No active NWS alert was returned for this forecast point.

Fishing usefulnessHelps

Skip or shorten the plan when the river is high or rising, cold storms are moving through, summer temperature checks are poor, or legal access and rule boundaries are not clear.

Trip notes

Trip notes

Check these before you choose a reach.

Best flows

Use RiverReports and USGS 01129200 below Indian Stream as the main trend for this report, then match it to the specific Pittsburg or downstream reach before wading.

When to leave

Skip or shorten the plan when the river is high or rising, cold storms are moving through, summer temperature checks are poor, or legal access and rule boundaries are not clear.

Local plan

Check the below-Indian-Stream flow, NH rules, stocking context, and weather, then pick one reach with safe footing, a clear exit, and enough cold water for trout handling.

Backup water

If the Upper Connecticut is high, cold, or unclear by reach, compare the Androscoggin, Saco, or Sugar River depending on travel direction and water temperature.

Below Indian Stream gauge reach

Primary flow reference for Pittsburg-area planning.

Pittsburg area

Northern access base with road and public/private checks.

North Stratford direction

Downstream context where the river broadens and conditions differ.

Public access is section-by-section. Confirm legal entry before leaving the road.

Border-region weather and remote roads require a backup plan.

Rules and fish composition can change downstream, so do not treat the whole Connecticut as one uniform reach.
