Tunmore Lake near Grand Marais: Fishing Spots, Seasons and Access

• Overview

  Tunmore Lake belongs to Cook County, Minnesota. Country round the bank runs to pine and birch. At 20 acres it is the sort of place you fish for an evening rather than a day. It is high ground by Minnesota standards. The town to know is Grand Marais, 15 miles out. Thunder Bay is the closest city, 66 miles away. No border sits close enough to matter.

• Where to Fish on Tunmore Lake

  Our records carry no depth, so judge it from the bank. On a natural lake the weed line and the shelf beyond it do the work. Read the surface for the wind lane, then fish the edge of it. Cook County records list white sucker, yellow perch, northern pike and rainbow trout among the fish reported. Records at county level tell you what is around, not what is stocked here. On Tunmore Lake a short move beats a long cast.

• Seasonal Patterns

  Typical July readings run about 63°F; by January the average is down near 5°F. The year splits cleanly: hard water, then open water. Ice is part of the season here, ending near late April. Climate averages put the opening at about late April and the closing near mid November. June through September is the settled part of the year, with the shoulders busier for fish. Tunmore Lake runs to that rhythm year in and year out.

• Tackle & Baits

  Who may fish here is not settled in anything we hold. We find no slipway, car park or made path within a short radius, so treat access as rough. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Look for a notice board at the entrance. Fishing rules and camping rules are set separately here. Ozada Lake sits 0.5 miles off and takes the overflow. Check the position at Tunmore Lake before loading the car.
