Thiebault Lake in Cass County: How and When to Fish It

• Overview

  Thiebault Lake is set in Cass County, Minnesota. The surface lies 1,342 feet up. Surface area is around 36 acres, which gives you real water without needing a boat. Cohasset is the closest place, 19 miles off. Fargo is the closest city, 140 miles away. The county line runs close by, so rules can change within a short drive. In wet weather the last stretch of track is the awkward part.

• Where to Fish on Thiebault Lake

  No figure exists for depth, so let the water show you. Still water like this holds fish on the edges rather than out in the open. The productive water is a rod length or two out, not a hundred. Reported across Cass County: largemouth bass, yellow perch and bluegill. Records at county level tell you what is around, not what is stocked here. The shape of Thiebault Lake rewards a slow walk along one bank.

• Seasonal Patterns

  In an average year July sits at 67°F and January at 5°F. A solid cap is the normal state through winter. Ice fishing carries the winter, and the water opens about mid April. Average temperatures cross freezing around mid April in spring and again near late November in autumn. June through September is the settled part of the year, with the shoulders busier for fish. Thiebault Lake runs to its own calendar within the local pattern.

• Tackle & Baits

  Nothing we hold confirms whether access is permitted. Mapping shows no built access close by; expect to walk in from wherever you can leave the car. A small crankbait along the drop and a worm in the thick stuff cover the bass. Rules for this water may differ from the county norm. Check whether bait restrictions apply before you buy any. If the gate is shut, Sailor Lake at 0.8 miles is the nearest alternative. Check the position at Thiebault Lake before loading the car.
