Lac a Grimper is listed under Mauricie, Quebec. What surrounds it is rolling bush. Start from La Tuque, 38 km down the road. Saguenay sits 138 km out, and it is the nearest city worth the name. Others close at hand: Lac Purcell 0.6 km off, Lac Laroche within 0.8 km, Lac des Hauteurs 0.9 km off, Lac Hero within 1.3 km and Lac Chasseur 1.3 km off. No boundary runs near, so the local rules hold throughout.
No published figure covers depth, so learn it as you fish. On a natural lake the weed line and the shelf beyond it do the work. The productive water is a rod length or two out, not a hundred. Reported across Mauricie: northern pike, brook trout, walleye, yellow perch and white sucker. Those are county-wide records, so not every one of them will be in this water. The near bank of Lac a Grimper is often the one people ignore.
Temperature averages peak at 17°C in July and bottom out at -16°C in January. Spring and autumn carry the fishing; summer and winter test it. Break-up comes around late April, and the run that follows is short and strong. Break-up sits around late April on average, with the water closing again about mid November. Right after break-up, and again as the nights sharpen, is when to go. It sets the rhythm of the year at Lac a Grimper.
Whether the bank is open is not something our records settle. No launch point is recorded nearby, so this is a bank water unless you carry a boat in. A small crankbait along the drop and a worm in the thick stuff cover the bass. Ask in the nearest town if you are unsure. Barbless rules turn up on managed water more often than not. Should this one be busy, Lac Purcell is 0.6 km off. Confirm access to Lac a Grimper locally before you travel.
