Thrasher Lake Fishing near Grand Marais, Minnesota

• Overview

  Thrasher Lake is set in Cook County, Minnesota. The water sits 2,077 feet up. About 22 acres of surface, which puts the far bank inside easy sight. By elevation it is in the upper part of our Minnesota listings. The closest town, Grand Marais, is 12 miles distant. The big place round here is Thunder Bay, 66 miles distant. The nearest boundary is well away, so one set of rules covers the water.

• Where to Fish on Thrasher Lake

  Nothing in our records gives a depth for this one. A natural lake fishes on cover, and cover here means weed and timber. Where the bottom changes texture, fish gather; find that line. Fish documented in Cook County include white sucker, yellow perch and northern pike. The county list is broader than any single water. Thrasher Lake gives up more to patience than to distance.

• Seasonal Patterns

  Average temperature peaks around 63°F in July and bottoms out near 6°F in January. Four clear seasons, with a proper winter at one end. Firm cover through the cold months, then open water from late April. Climate averages put the opening at about late April and the closing near mid November. May into June fishes hardest, and September gives a second good stretch before the lid returns. Time your trip to Thrasher Lake by conditions rather than dates.

• Tackle & Baits

  Whether the bank is open is not something our records settle. Access is unmapped, which usually means a farm track and a walk. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Sort the permit out before you load the car. Where tickets apply, they are sold in the nearest town rather than on the bank. Thrush Lake at 0.2 miles is the sensible second choice. None of that is settled for Thrasher Lake in what we hold.
