Thayer Lake Fishing Guide, Johnson County, Wyoming

• Overview

  Thayer Lake lies in Johnson County, Wyoming. Everything around it is pine and birch. This is a pocket water of some 8 acres, and every part of it is reachable from the bank. For a base, Sheridan sits 27 miles out. Billings sits 108 miles out, and it is the nearest city worth the name. The nearest edge is a long way off, so local rules apply throughout.

• Where to Fish on Thayer Lake

  The records we hold are silent on depth, so plan to find it yourself. Still water like this holds fish on the edges rather than out in the open. The shallow end warms first and pulls fish in ahead of the rest. Reported across Johnson County: brown trout, rainbow trout, brook trout, white sucker and walleye. County data is a starting point rather than a guarantee. Thayer Lake gives up its fish to patience rather than distance.

• Seasonal Patterns

  The year swings from about 12°F in January to roughly 50°F in August. The year splits cleanly: hard water, then open water. Winter locks it down, and mid June brings it back. From about mid June to around late October, expect open water on the long-run figures. Right after break-up, and again as the nights sharpen, is when to go. Time your trip to Thayer Lake by conditions rather than dates.

• Tackle & Baits

  Access status is simply unknown for this water. The map shows no ramp or car park nearby, so this is a walk-in water. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Parking is often the real limit rather than the bank itself. Some stretches are reserved and marked as such on the ground. Devils Lake at 0.6 miles is the sensible second choice. Nothing on Thayer Lake should be assumed from this page alone.
