Upper Seymour Lake Fishing near Anaconda, Montana

• Overview

  Upper Seymour Lake is listed under Deer Lodge County, Montana. Everything around it is lake country bush. It runs to roughly 40 acres — big enough to hold fish away from the bank, small enough to learn. The full circuit measures close to 1.0 miles on foot. Few waters listed in Deer Lodge County are bigger. You are 17 miles from Anaconda. Warm Springs is 25 miles and Butte 35 miles. The county line is nowhere near, so one local authority covers the water.

• Where to Fish on Upper Seymour Lake

  Depth is not on record here, so the bank has to tell you. A soft bed grows weed late into autumn, which keeps fish shallow. Bays and points beat straight shoreline every time on water like this. Survey and observation records for Deer Lodge County include rainbow trout, brook trout and Arctic grayling. Read it as a county summary, not a water-by-water list. On Upper Seymour Lake that means starting tight and working out.

• Seasonal Patterns

  Expect July near 51°F and December near 17°F on the long-run figures. Cold locks it up for a good stretch each year. Count on hard cover from midwinter, and open water from late May. Break-up sits around late May on average, with the water closing again about early November. The shoulder weeks of the open season are the productive ones. Upper Seymour Lake runs to that rhythm year in and year out.

• Tackle & Baits

  Public sources are silent on who controls the bank. Records list it as a natural water body rather than an impoundment. Public mapping records no formal access here, so plan for a walk and soft ground. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry. Where the road in crosses private land, ask first. Some ground is open by custom rather than by right, so tread carefully. Emerald Lake sits 1.4 miles off and takes the overflow.
