Pemigewasset River Fishing Map & Spots (NH)

Hatch outlook

Blue-Winged OlivesActive window

Typical here: Apr 1 – Nov 15 · multiple broods, strongest spring and fall; tailwaters like the Farmington carry olives essentially year-round

dunmidday into afternoon — the gray, drizzly days produce the real hatches

The bad-weather insurance hatch: the days that look wrong are the BWO days.

Overcast olive days keep trout feeding all day instead of one window: micro-spoons, small dark inline spinners and 1/32 oz jigs through the seams right through the gloom. The tiny fall olives are past what hardware matches — go bubble-and-olive-wet or fish the jig.

The event happens over riffles, seams and flats throughout the river

Terrestrials (ants, beetles, hoppers)Active window

Typical here: Jun 1 – Oct 31 · ants and beetles from June; hoppers and crickets strongest mid-July through September

adultmidday and afternoon — the hotter and windier, the better the bank bite

No hatch clock — wind is the conveyor; the fish move to the grassy banks and stay there all summer.

Summer's bank bite is spin-friendly: small poppers, micro spinnerbaits and inline spinners upstream tight to grassy undercut banks on breezy afternoons. The bubble-and-foam-beetle rig is deadly and nobody fishes it.

The event happens over grassy, brushy banks and the seams just off them, on warm windy afternoons

October Caddis (Great Autumn Brown Sedge)Active window

Typical here: Aug 15 – Nov 15 · peak late September into October — the biggest caddis of the New England fall

pupalate afternoon into dark — many pupae drift long distances before slowing in shallow water; emergence proper is by crawling out on shore at dusk or night — fish the drift and the shoreline margins, not mid-river rises
ovipositingdusk and after dark — females twitch and flop on the surface laying eggs — skate the dry; some crawl UNDERWATER from shoreline objects to lay, so a wet swung along the bank works too

Never a blanket hatch — a big, sparse bug the fish know; its value is prospecting weight in a thin-hatch season.

Fall fish on big sparse bugs are ambush-minded: small orange and brown crankbaits and inline spinners along wood and slow bank water in the last light. It's also landlocked-salmon-run season on many of these rivers — the same dusk water holds them.

The event happens over slow water with wood — banks, deadfalls and eddies, in the evening

Fishing Pemigewasset River: what the data says

Thornton to Plymouth The river tops out around 6 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. What the data behind the map says about each species, season by season:

The outline encloses 192 acres, worked by 23.6 miles of shoreline. That shoreline is heavily fingered (development index 12.2) — bays, points and pockets everywhere, which multiplies the fishable edge. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Tip to tip the water measures near 9.6 mi with a 1.4-mi widest point. Grafton County claims this one. If the bite dies, Perch Pond is 4 mi to the southeast.

Rainbow Trout fishing at Pemigewasset River

Spring rainbow trout on Pemigewasset River hold shallow, usually 2 to 6 ft. Depth-wise the year is flat: 2 to 6 ft in summer, 1 to 6 ft once it turns cold. Put Current seam (mile 8.1) first on the milk run — a current seam near 5 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.

Season	Depth	Best window	Start at	Go-to baits
Spring	2 to 6 ft	dawn & dusk	Current seam (mile 8.1) (5 ft)	Inline spinner (silver), Small spoon
Summer	2 to 6 ft	dawn & dusk	Current seam (mile 8.1) (5 ft)	Dodger + spoon (deep troll), Flutter spoon
Fall	2 to 6 ft	dawn & dusk	Current seam (mile 8.1) (5 ft)	Casting spoon, Jerkbait over shoals
Winter	1 to 6 ft	dawn	Current seam (mile 8.1) (5 ft)	Jigging spoon, Tube jig (white)

Smallmouth Bass fishing at Pemigewasset River

When the water first warms, smallmouth bass slide up into 2 to 6 ft. There's no big seasonal slide here — summer means 2 to 6 ft, winter 2 to 6 ft. If you only fish one area, make it Riffle & run (mile 0.6): a rock pile around 3 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.

Season	Depth	Best window	Start at	Go-to baits
Spring	2 to 6 ft	dawn & dusk	Riffle & run (mile 0.6) (3 ft)	Ned rig, Tube jig
Summer	2 to 6 ft	dawn & dusk	Riffle & run (mile 0.6) (3 ft)	Drop shot (goby/minnow), Ned rig
Fall	2 to 6 ft	midday & dawn	Inside bend (mile 1.5) (4 ft)	Jerkbait, Blade bait
Winter	2 to 6 ft	midday	Current seam (mile 8.1) (5 ft)	Blade bait, Hair jig

Brook Trout fishing at Pemigewasset River

Early season brook trout use the shallows, holding in 1 to 6 ft. Even in summer they hold at 2 to 6 ft; winter keeps them in 1 to 6 ft. The chart's best answer is Current seam (mile 8.1) — current seam, 5 ft, prime for spring. Best bite is early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.

Season	Depth	Best window	Start at	Go-to baits
Spring	1 to 6 ft	dawn & dusk	Current seam (mile 8.1) (5 ft)	Small inline spinner (gold), Tiny spoon
Summer	2 to 6 ft	dawn & dusk	Current seam (mile 8.1) (5 ft)	Small spoon fished deep, Trolled lake-clear wobbler + worm
Fall	1 to 6 ft	midday & dawn	Current seam (mile 8.1) (5 ft)	Small spoon (orange), Spinner
Winter	1 to 6 ft	dawn	Current seam (mile 8.1) (5 ft)	Small jigging spoon, Tungsten jig + plastic

Brown Trout fishing at Pemigewasset River

In spring, brown trout run shallow here, mostly 1 to 6 ft. Summer keeps them at 2 to 6 ft, and they winter in 1 to 6 ft. Current seam (mile 8.1) is the standout, a current seam at roughly 5 ft, rated prime for summer brown trout. Time it for after dark and early morning. You won't need more than a spoon at the thermocline or a deep stickbait (night) most summer days.

Season	Depth	Best window	Start at	Go-to baits
Spring	1 to 6 ft	dawn & dusk	Eddy pocket (mile 3.9) (5 ft)	Stickbait off planer boards (shallow), Small spoon along mud lines
Summer	2 to 6 ft	night & dawn	Current seam (mile 8.1) (5 ft)	Spoon at the thermocline, Deep stickbait (night)

Winter	1 to 6 ft	dawn	Eddy pocket (mile 3.9) (5 ft)	Jigging spoon, Small stickbait (slow)

Rock Bass fishing at Pemigewasset River

Start shallow in spring: rock bass sit in 1 to 6 ft that time of year. They don't go far with the seasons — 2 to 6 ft covers summer, 2 to 6 ft covers winter. Top water on the chart: Riffle & run (mile 0.6), a rock pile in the 3 ft range, prime in spring. Fish it in the evening and you'll meet the bite. Throw a ned rig (small) or a marabou jig until the fish tell you otherwise.

Season	Depth	Best window	Start at	Go-to baits
Spring	1 to 6 ft	midday & dawn	Riffle & run (mile 0.6) (3 ft)	1/16 oz jig + grub, Small inline spinner
