Solid cloud cover today, with a useful WNW wind pushing food about and steady pressure. Grim Lake should fish best around inflow corners and shaded margins today. Not a day the forecast likes; the night keeps a flicker of interest. Lower the pace and stay patient. Falling temperatures are switching fish back on.

You will find Grim Lake in Kenora District, Ontario. The surface lies 454 metres up. Roughly 39 hectares: a morning covers one end, an afternoon the other. Shoreline comes to about 2.8 km, small enough to learn in a day. Compared with other Ontario water on our list, it sits high. Nearest place of any size is Ignace, 20 km away. Atikokan lies 67 km off, Sioux Lookout another 90 km. The county line is nowhere near, so one local authority covers the water.
We hold no depth figure for this one. Weed, then depth: that is the order to fish a water of this kind. The shallow end warms first and pulls fish in ahead of the rest. Public occurrence data for Kenora District names northern pike, longnose sucker, white sucker and johnny darter. Records at this level tell you what is in the area. The near bank of Grim Lake is often the one people ignore.
Averages move between -19°C in January and 18°C in July. Hard water is a season in its own right here. Firm cover through the cold months, then open water from late April. Open water usually runs from late April until about mid November. Spring is short and heavy here; autumn is longer and steadier. It holds true on Grim Lake more years than not.
Public data does not answer the access question here. No dam controls it, and the level follows the season. Mapping is blank for access, so scout the approach before committing the car. For the pike, wire up and throw larger lures along the weed edges. Check locally before you travel, because a wasted drive is a long one. Rules for boats are stricter than rules for the bank in many places. South Lake, 1.1 km away, makes the obvious fallback. Nothing on Grim Lake should be assumed from this page alone.
