A still, cloudless night on the water, with just enough S wind to ripple the surface and pressure going nowhere. Whatever swims in Lac Grosleau should be near the margins and the shelf beyond them. The night carries the best of the day. Fish tidy and take what the day gives. The pre-winter feed makes autumn days generous.

Night
Lac Grosleau belongs to Outaouais, Quebec. It sits in mixed forest. Roughly 24 hectares: a morning covers one end, an afternoon the other. It is low-lying compared with other Quebec water we list. Ripon sits 4.1 km from here and is the nearest stop. After that come Saint-André-Avellin at 11 km and Notre-Dame-du-Mont-Carmel at 22 km. No county line comes close, which keeps the paperwork simple.
We hold no depth figure for this one. Still water like this holds fish on the edges rather than out in the open. This is a lake, so the margins and the first drop matter most. Survey and observation records for Outaouais include pumpkinseed, yellow perch, smallmouth bass and rainbow smelt. What holds for the county may not hold for this water. On Lac Grosleau the first feature you find is usually worth a session.
On the long-term average, July reads 19°C and January reads -13°C. Winter puts a hard lid on this one. Count on hard cover from midwinter, and open water from late April. On the long-run averages the water opens up around late April and starts locking again about early December. The weeks after the thaw and the ones before the freeze are the strongest. Anyone fishing Lac Grosleau regularly works to that calendar.
We have no record of the rules that apply on this bank. Nothing built is recorded close to the bank here. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Rules differ from one water to the next round here. Where parking is tight, arriving early solves most problems. If the gate is shut, Lac Simonet at 1.4 km is the nearest alternative. Check the position on Lac Grosleau before loading the car.
