Today's Fishing Report

Generated this morning from live readings: gauge, weather model, sun and moon. A fresh report is published here every morning.

4/5Good. Solid day ahead.Stable-to-falling pressure and workable wind line things up.

West Branch Penobscot River sits in the sweet spot of the season: active fish and workable weather. Today brings cloud cover, wind NW around 6 mph, rising pressure near 1009 hPa and a high of 69. Water sits around 66 F for the season (estimated). With the last quarter, the solunar majors run 5:39 AM-7:39 AM and 5:39 PM-7:39 PM: the windows to build the day around.

The plan, species by species

Landlocked salmonExcellent

Transition depths: work 15-30 ft along drop-offs and points with trolled smelt imitations, or find them where cold tributaries enter. Early morning is the honest window.

Brook troutExcellent

Prime pocket-water fishing. Work upstream with an attractor dry or a dry-dropper, hitting every seam behind boulders and the head of each plunge pool. Short casts, quiet feet.

Brown troutExcellent

Terrestrials tight to the bank; streamers through the deeper runs on cloudy days.

Tomorrow: Cooler at 63 F. The solunar majors shift about 50 minutes later.Next report: Sat, Sep 5, 6:30 AMHow this report is made →

Landlocked salmon illustration

Landlocked salmon

Best: ice-out through June, and September

Atlantic salmon that never see the sea: smelt-chasing acrobats of Maine and New England lakes, and the reason ice-out is a holiday up north. Transition depths: work 15-30 ft along drop-offs and points with trolled smelt imitations, or find them where cold tributaries enter. Early morning is the honest window.

Brook trout illustration

Brook trout

Best: May-Jun and Sep-Oct

North America’s native char: a small-stream specialist that demands cold, clean water and repays it with the prettiest fish in the woods. Prime pocket-water fishing. Work upstream with an attractor dry or a dry-dropper, hitting every seam behind boulders and the head of each plunge pool. Short casts, quiet feet.

Brown trout illustration

Brown trout

Best: Sep-Nov

Wary, predatory and nocturnal by preference. The big ones eat streamers. Terrestrials tight to the bank; streamers through the deeper runs on cloudy days.

About this water

A dam-controlled river from Ripogenus Dam past Baxter State Park, Piscataquis County, Maine: landlocked salmon and brook trout water.

Fishing West Branch Penobscot River: the full guide

The river below the gorge

The West Branch of the Penobscot leaves Ripogenus Dam and drops through a gorge into a broad, boulder-strewn river running east past Mount Katahdin. Cold dam releases hold summer temperatures in the trout-and-salmon range, and the salmon here have a reputation as the hardest-fighting landlocks in Maine: river-raised fish in heavy current that use every ounce of the flow. Brook trout share the water, and the setting: Baxter State Park’s peaks over the treeline: is the postcard of Maine fishing.

Fishing heavy current

The classic water runs from Big Eddy down through the Horserace and the Cribworks toward Nesowadnehunk. Anglers swing streamers on sink tips through the seams, drift nymphs along the boulder edges, and in summer fish caddis and mayfly hatches in the softer water. The salmon average 14-18 inches and fight above that class. Wading is genuinely serious: the current is powerful, the boulders are round, and a staff and studs are the minimum.

Flows and the season

Releases from Ripogenus control everything, and whitewater rafting releases raise the river on a published schedule through the summer: check it, because a rafting day changes the fishing entirely. The season runs from spring through September, with June and September the strongest windows. Insects are prolific: caddis in early summer, then a good fall of terrestrials and mayflies through the warm months.

North woods access

The Golden Road, a private logging road open to the public with fees at checkpoints, provides access to Big Eddy, Abol and the campsites along the river. Big Eddy campground is the traditional base. Facilities are minimal, cell service is absent, and Millinocket, an hour away, is the last real town. Plan fuel, food and a spare tire before turning onto the road.

Common questions

Why are these salmon special?

They are river fish in heavy current with a reputation for extraordinary fights: a sixteen-inch West Branch salmon behaves like a much larger fish elsewhere.

How hard is the wading?

Difficult: strong current over round boulders in cold water. Studded boots, a staff and conservative choices are the sensible approach.

Do rafting releases matter?

Very much: scheduled whitewater releases raise flows dramatically. Check the release calendar before planning a day on the river.
