Gannon Lake in Saint Louis County: How and When to Fish It

• Overview

  Gannon Lake is one of the Saint Louis County listings for Minnesota. Beyond the shoreline you have rolling bush. The water covers some 93 acres, so pick a bank rather than trying to cover it all. Bank access stretches around 2.0 miles in total. International Falls sits 36 miles from the bank. Thunder Bay is the closest city, 160 miles away. No boundary runs near, so the county rules hold throughout.

• Where to Fish on Gannon Lake

  There is no recorded depth, so work from what you can see. Bays and points beat straight shoreline every time on water like this. On a natural lake the weed line and the shelf beyond it do the work. Across Saint Louis County, recorded fish include yellow perch, northern pike, white sucker and rainbow trout. The county figures include rivers and lakes alike. The shape of Gannon Lake decides where the fish sit.

• Seasonal Patterns

  Temperature averages peak at 66°F in July and bottom out at 4°F in January. Winter shuts things down for a spell, then spring reopens them fast. Ice-out usually falls in late April, and the weeks after it fish hardest. The open-water window runs from around late April to about mid November in an average year. The strongest runs come at either end of the open season. That is the shape of the year on Gannon Lake.

• Tackle & Baits

  Ownership and access are not documented in what we hold. No dam controls it, and the level follows the season. Nothing is mapped in the way of a ramp or car park within a short radius. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Look for a notice board at the entrance. Rules for boats are stricter than rules for the bank in many places. For a change of water, Bluebird Lake is 1.5 miles distant. Nothing here settles the position at Gannon Lake for certain.
