Lac Grosbois Fishing Guide, Mauricie, Quebec

• Overview

  Within Mauricie, Quebec, you have Lac Grosbois. What surrounds it is mixed forest. About 1.31 sq km, so local knowledge or a boat saves a lot of walking. Around 8.4 km of bank, which is a long day on foot. Size puts it in the front rank of our Mauricie list. Some 36 km away sits La Tuque, the nearest settlement. The nearest city of size is Trois-Rivières, 88 km away. It sits well inside its county, with no border complications.

• Where to Fish on Lac Grosbois

  Depth is not on record here, so the bank has to tell you. On a natural lake the weed line and the shelf beyond it do the work. Weed, then depth: that is the order to fish a water of this kind. Across Mauricie, recorded fish include northern pike, brook trout, walleye and yellow perch. The county figures include rivers and lakes alike. On Lac Grosbois that means starting tight and working out.

• Seasonal Patterns

  Long-run averages give July about 18°C and January about -15°C. Winter puts a hard lid on this one. Hard water holds through the cold months, breaking up near late April. Averages place the thaw at late April and the freeze at late November. Spring is short and heavy here; autumn is longer and steadier. Plan around that when you fish Lac Grosbois.

• Tackle & Baits

  Nothing in our records says who may fish here. Records list it as a natural water body rather than an impoundment. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Parking space is the usual limit rather than the bank itself. Where tickets apply, they are sold in the nearest town rather than on the bank. Failing this one, try Lac Lemere, 2.2 km away. Where Lac Grosbois is concerned, a local answer beats a written one.
