Flat light and a covered sky today, with steady pressure of wind from the S with the barometer flat. Give the calm side of the wind the first hour at Petit lac Bostonnais. Make the night the heart of the trip. Fish tidy and take what the day gives. Fish follow the bait in autumn, so find one to find the other.

Petit lac Bostonnais lies in Mauricie, in Quebec. It stands 376 metres above sea level. At some 1.29 sq km it is far too large to cover on foot in a day. It ranks high for size among our Mauricie listings. Métabetchouan sits 60 km from the bank. Beyond it, La Tuque at 60 km and Chambord at 66 km. Other water nearby: Lac du Midi at 1.2 km, Lac du Cerf just 1.5 km, Lac au Foin at 1.7 km, Lac Trudel just 1.8 km and Lac de la Vase at 2.5 km. This one is safely inside the county line.
Nothing in our records gives a depth for this one. Still water like this holds fish on the edges rather than out in the open. On a natural lake the weed line and the shelf beyond it do the work. Survey and observation records for Mauricie include northern pike, brook trout, walleye and yellow perch. The list covers the county rather than this water alone, so treat it as a guide. The shape of Petit lac Bostonnais rewards a slow walk along one bank.
The warm month here averages 17°C; the cold one sits at -16°C. Everything is compressed into the middle of the year. The lid arrives early and lasts until roughly early May. Going by climate averages, expect open water from about early May until roughly mid November. Just after the ice goes and just before it returns, the fishing lifts. The season on Petit lac Bostonnais follows the weather closely.
Who may fish here is not settled in anything we hold. We find no slipway, car park or made path within a short radius, so treat access as rough. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Where access is informal, keep it that way by behaving. Some stretches are reserved and marked as such on the ground. Lac du Midi sits 1.2 km off and takes the overflow. Confirm access to Petit lac Bostonnais locally before you travel.
