Iris Lake in Cook County: How and When to Fish It

• Overview

  Cook County in Minnesota is where Iris Lake sits. It lies 1,827 feet above sea level. At about 30 acres, a day is enough to walk the shoreline properly. About 1.1 miles of bank, so nothing stays unexplored for long. Compared with other Minnesota water on our list, it sits high. Grand Marais is the closest place, 29 miles off. For a city, Thunder Bay is 78 miles off. It lies deep inside the county rather than near an edge.

• Where to Fish on Iris Lake

  Nothing in our records gives a depth for this one. Read the surface for the wind lane, then fish the edge of it. The productive water is a rod length or two out, not a hundred. Across Cook County, recorded fish include white sucker, yellow perch, northern pike and rainbow trout. Those are county-wide records, so not every one of them will be in this water. At Iris Lake the first feature you find is worth twenty minutes.

• Seasonal Patterns

  In an average year July sits at 63°F and January at 5°F. Hard water is a season in its own right here. Count on hard cover from midwinter, and open water from late April. Average temperatures cross freezing around late April in spring and again near mid November in autumn. Fish feed hardest at the start and the close of the open season. Plan any trip to Iris Lake around it.

• Tackle & Baits

  We hold no note on access for this one. No dam controls it, and the level follows the season. Mapping shows an empty shoreline: no ramp, no jetty, no marked entry. A small crankbait along the drop and a worm in the thick stuff cover the bass. Some banks are open only from a marked point. Some water is controlled locally without a sign saying so. Failing this one, try Fetters Lake, 0.4 miles away. Treat Iris Lake as unsettled until someone local tells you otherwise.
