Upper Seymour Lake is a lake in Deer Lodge County, Montana.

Use the shape you can see at Upper Seymour Lake: check the best cover, the first drop, and one open-water line before moving.

Fish and Baits

Along the narrow end of a windblown shore, the fish mix here is not confirmed, so check fresh local information before choosing a target or keeping a catch.

Along the hard edge of a small island, begin with one slow bottom presentation and one moving bait, then let bites show whether fish are holding close to cover or roaming open water.

How to Read the Water

Along the clearer side of the old channel, do not let the deepest number control the whole day; nearby cover, firm bottom, and food usually matter more than the deepest hole by itself.

Season by Season

Beside the first edge of a deep bend, spring runoff can add color and pull fish toward fresh water; green weeds and the first drop become stronger summer targets; in fall, follow bait toward points and shallow flats, while winter rewards a slower search.

A Simple Tackle Plan

Across the calm side of a sand-to-rock change, a medium spinning rod, 8-pound line, a small box of jigs, a few crankbaits, and a simple bottom rig cover most situations; change depth or speed before changing every piece of tackle.

Around the soft edge of a deep bend, record the wind, water color, depth of the first good pass, and cover after a bite; those four notes are more useful on the next trip than a long list of spots that did not produce.
