Scattered cloud dimming the moonlight, with a faint W drift with the glass holding level. Union Lake should fish best around the weed line and any gaps in it today. The day holds up well from afternoon into evening. Work the productive water thoroughly. Cooling water has fish active and on the move.

Union Lake sits within Algoma in Ontario. It sits in pine and birch. Around 28 hectares of surface means several distinct areas to work. The shoreline runs about 5.7 km, so it pays to pick a stretch and stay with it. Compared with other Ontario water on our list, it sits high. Supplies mean a trip to Wawa, 86 km off. Beyond it, Sault Ste. Marie at 87 km and Chapleau at 89 km. Rules here are straightforward: one set of provincial rules.
There is no recorded depth, so work from what you can see. Where the bottom changes texture, fish gather; find that line. Still water like this holds fish on the edges rather than out in the open. Species logged across Algoma include walleye, northern pike, Iowa darter and yellow perch. Take it as the county picture rather than a promise for this water. Read Union Lake for ten minutes before the first cast goes out.
Averages here run 16°C at the top of summer and -14°C at the bottom of winter. The year splits cleanly: hard water, then open water. The freeze runs deep into the year, with break-up near late April. In an average year the thaw lands around late April and the freeze near late November. September and October fish steadily right up to the freeze. Time your trip to Union Lake by conditions rather than dates.
Ownership and access are not documented in what we hold. No dam controls it, and the level follows the season. Nothing built is recorded close to the bank here. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. A phone call first saves an afternoon. Night access is frequently treated as a separate matter. The nearest alternative is Mallot Lake, 2.1 km out. Confirm access to Union Lake locally before you travel.
