A grey, even sky over the water, with dead-still conditions and pressure going nowhere. Fish at Grindstone Lake should hold close to the shaded margin through bright spells. If you pick one session, make it the middle of the day. Keep moving until you find them. A hard-frost feel to the day; keep expectations modest.

Grindstone Lake is set in Manitoba. The ground round it is boreal forest. Roughly 92 hectares: a morning covers one end, an afternoon the other. Shoreline length is close to 5.6 km, and each section fishes a little differently. Nearest town is Thompson, 135 km off. It is 629 km to Saskatoon, the nearest city. Rules here are straightforward: one set of provincial rules.
Depth figures are not published for this one. Read the surface for the wind lane, then fish the edge of it. On a natural lake the weed line and the shelf beyond it do the work. On Grindstone Lake a short move beats a long cast. Sunken timber holds fish, but costs tackle; go in prepared.
The seasonal spread runs -25°C to 16°C. This is a two-season water: locked, then wide open. Break-up comes around mid May, and the run that follows is short and strong. From about mid May to around early November, expect open water on the long-run figures. The shoulder weeks of the open season are the productive ones. Keep it in mind when planning a trip to Grindstone Lake.
Public data does not answer the access question here. This is a natural basin, not a dammed one. Nothing is listed nearby for parking or launching a boat. Rules differ from one water to the next round here. Close seasons apply to some species and not others. Goodwin Lake sits 2.4 km off and takes the overflow. For Grindstone Lake, the notice at the access point is the final word.
