Today's Fishing Report

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

2/5Slow. The wind owns today.25 mph gusts make boat control the real battle.

Fort Peck Lake rewards those who follow the bait as the water cools. Today brings clear skies, wind WNW around 18 mph, steady pressure near 999 hPa and a high of 63. Water sits around 55 F for the season (estimated). With the waxing gibbous, the solunar majors run 9:44 AM-11:44 AM and 10:15 PM-12:15 AM: the windows to build the day around.

The plan, species by species

WalleyeGood

Spring: post-spawn fish scatter and can be slow for a couple of weeks. Fall: one of the best windows, with minnows on jigs and three-way rigs as the water cools toward ice-up.

Lake troutGood

Spring and fall bring lakers into 10 to 30 feet of water (Michigan DNR), within reach of casters and shallow trollers; fall is also spawning time over rocky shoals.

Chinook salmonSlow

Runs enter the rivers: drift roe or sand shrimp through travel lanes, plunk a wrapped plug, or float eggs in eddies and tidewater.

Tomorrow: Cooler at 44 F with a rain chance. The solunar majors shift about 50 minutes later.Next report: Sat, Oct 24, 6:30 AMHow this report is made β†’

Species guide

The species that matter on Fort Peck Lake: seasons, structure and how to fish each one. Today's ratings live in the report above.

Walleye illustration

Walleye

Best: spring and late fall, around dawn, dusk and night

A cool-water perch of large lakes, reservoirs and rivers whose reflective eyes are built for low light, so it feeds most at night and in murky water. The Missouri Department of Conservation ranks it among the continent's most important freshwater game fish. Spring: post-spawn fish scatter and can be slow for a couple of weeks. Fall: one of the best windows, with minnows on jigs and three-way rigs as the water cools toward ice-up.

Chinook salmon illustration

Chinook salmon

Seasons follow the runs: spring, summer and fall runs on the West Coast, and late summer into fall in Great Lakes rivers

The largest Pacific salmon, caught by trolling and mooching at sea and by drifting and plunking in rivers as adults return to spawn; also stocked in the Great Lakes. Runs enter the rivers: drift roe or sand shrimp through travel lanes, plunk a wrapped plug, or float eggs in eddies and tidewater.

Lake trout illustration

Lake trout

Spring and fall in shallow water, deep in summer, and through the ice in winter

Lake trout are slow-growing chars of large, deep, cold lakes, native from Alaska and northern Canada to New England and the Great Lakes, and introduced in many western lakes. Spring and fall bring lakers into 10 to 30 feet of water (Michigan DNR), within reach of casters and shallow trollers; fall is also spawning time over rocky shoals.

About this water

Fort Peck Lake, a Corps of Engineers reservoir on the Missouri River in northeastern Montana, authorized in 1933, with about 1,500 miles of shoreline.

Fishing Fort Peck Lake: the full guide

The reservoir

The Corps of Engineers says Fort Peck Dam, which impounds Fort Peck Lake, was the first dam built in the upper Missouri River basin; President Franklin D. Roosevelt authorized the project in 1933. The Corps describes the lake as vast and remote, with fifteen hundred miles of shoreline and 27 recreation areas. Areas near the dam have paved roads, electricity, showers and playgrounds, while facilities around the rest of the lake are primitive, with gravel roads, picnic tables and vault toilets.

Walleye, sauger and salmon rules

Montana FWP's 2026 regulations give Fort Peck Reservoir its own exceptions to the Eastern District standard limits. Sauger and walleye: 5 a day, of which only 2 may be sauger, and 10 in possession, of which only 4 may be sauger. Chinook salmon may be snagged only from October 1 through November 30 and taken by bow and arrow from October 1 through October 15. Chinook salmon and lake trout may be speared or gigged through the ice from December 1 through March 31. Dead cisco may be used as bait only if collected from the reservoir or from the Missouri River below Fort Peck Dam.

Eurasian watermilfoil and bait

FWP lists Fort Peck Reservoir, the Fort Peck Dredge Cut Ponds and the Missouri River from Fort Peck Dam to the mouth of the Milk River as contaminated with Eurasian watermilfoil. Live nongame bait fish may be carried to and from those waters only in clean water, such as well water.

Common questions

How many walleye can I keep at Fort Peck?

Five sauger and walleye a day, of which only two may be sauger, and ten in possession, of which only four may be sauger.

Can I snag salmon on Fort Peck?

Only Chinook salmon, and only from October 1 through November 30. Bowfishing for Chinook is allowed October 1 through 15.

What bait can I use at Fort Peck?

Dead cisco may be used as bait if it was collected from the reservoir or from the Missouri River below Fort Peck Dam. Live nongame bait fish must be transported to and from the lake only in clean water because of Eurasian watermilfoil.

How this page was made. The daily report is computed by our scoring engine from live readings; nobody types it. The written text was drafted with AI assistance from the official pages listed above, and its facts were checked against those pages by automated verification on October 6, 2026; anything that could not be verified was taken out. Pablo Ruiz Quintero sets every guideline, the data-verification system and the minimum standards a page must meet to be published, reviews page structure and approves what goes live; the responsibility is his, and the AI carries out the work. We work this way because it is how one person can keep every page current with named sources. Errors are published in the verification log; the full policy is in the editorial policy.
