Rain on and off through the day, with a persistent wind from the WNW and the barometer holding steady. Expect most activity at Gratton Lake around points where shallow meets deep. A long productive spell runs the day. A careful, quiet approach will out-fish a busy one. Autumn rewards covering water while the fish roam.

Gratton Lake is set in Rainy River District, Ontario. It lies 391 metres above sea level. It runs to roughly 25 hectares — big enough to hold fish away from the bank, small enough to learn. The whole outline is near 3.8 km, and most of it is walkable. It is one of the smaller waters we list in Rainy River District. The nearest town is Ely, 45 km away. Atikokan lies 53 km off, Babbitt another 67 km. No county line comes close, which keeps the paperwork simple.
There is no recorded depth, so work from what you can see. Look for the band where the shallows give up and the bottom falls away. Bays and points beat straight shoreline every time on water like this. Records held for Rainy River District cover northern pike, smallmouth bass and yellow perch. It is the county picture; the agency list is water-specific. Gratton Lake gives up its fish to patience rather than distance.
The year swings from about -16°C in January to roughly 19°C in July. Winter shuts the surface down for months. The lid arrives early and lasts until roughly late April. The open-water window runs from around late April to about mid November in an average year. Right after break-up, and again as the nights sharpen, is when to go. On Gratton Lake that shapes the whole year.
Access status is simply unknown for this water. No dam controls it, and the level follows the season. No launch point is recorded nearby, so this is a bank water unless you carry a boat in. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Gates get locked out of season on water like this. Where the way in crosses private ground, ask first. Shaw Lake sits 2.2 km off and takes the overflow. The position on Gratton Lake is worth confirming on the day.
