O'Leary Lake, Minnesota: Fishing Spots and Seasons

• Overview

  Look for O'Leary Lake in Saint Louis County, Minnesota. This is pine and birch country. It measures about 197 acres, which is a comfortable size for bank fishing. With about 2.4 miles of edge, you can try several depths in one session. Size puts it in the front rank of our Saint Louis County list. The town to know is Fort Frances, 42 miles out. It is 151 miles to Thunder Bay, the nearest city. No border sits close enough to matter.

• Where to Fish on O'Leary Lake

  Depth is not on record here, so the bank has to tell you. A soft bed grows weed late into autumn, which keeps fish shallow. Look for the band where the shallows give up and the bottom falls away. Saint Louis County records list yellow perch, northern pike and white sucker among the fish reported. County data is a starting point rather than a guarantee. O'Leary Lake responds to conditions more than to tactics.

• Seasonal Patterns

  The warm month here averages 66°F; the cold one sits at 4°F. Winter puts a hard lid on this one. Once it clears, about late April, the fishing comes on quickly. Expect the water usable from around late April until roughly mid November. Just after the ice goes and just before it returns, the fishing lifts. That is the shape of the year on O'Leary Lake.

• Tackle & Baits

  Who may fish here is not settled in anything we hold. It formed naturally, so levels move with rainfall rather than with a gate. There is no mapped parking or launch close by, which usually means walking in. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Check whether a boat is allowed before you tow one. Check whether bait restrictions apply before you buy any. The nearest alternative is Little Trout Lake, 1.4 miles out. The position on O'Leary Lake is worth confirming on the day.
