Low, flat cloud sitting over the water, with mild air moving in from the SSW and pressure going nowhere. The productive water at Lac Boy will be around points where shallow meets deep. If you pick one session, make it the night. Work the productive water thoroughly. Autumn fish are feeding up and less fussy than in summer.

You will find Lac Boy in Mauricie, Quebec. It sits at 440 metres above sea level. It measures about 22 hectares, which is a comfortable size for bank fishing. Around 2.9 km of margin, front to back. For supplies, Weymontachie is 47 km out. Leblanc is 47 km away, with Manawan at 70 km. Also on the doorstep: 1.7 km out stands Lac Johnson, Lac Ruth after 3.1 km, 3.5 km out stands Lac Faessler, Lac Baxter after 3.7 km and 3.8 km out stands Lac Letondal. There is no boundary nearby to worry about.
Nothing we hold settles how deep this runs. A soft bed grows weed late into autumn, which keeps fish shallow. This is a lake, so the margins and the first drop matter most. Open biodiversity records for Mauricie list northern pike, brook trout, walleye, yellow perch and white sucker. The county figures include rivers and lakes alike. At Lac Boy the first feature you find is worth twenty minutes.
Long-term averages put July at about 16°C and January near -17°C. This is a two-season water: locked, then wide open. The freeze runs deep into the year, with break-up near early May. Averages suggest open water from about early May through to roughly mid November. Late spring and early autumn carry the year between them. Plan any trip to Lac Boy around it.
We have no record of the rules that apply on this bank. Records list it as a natural water body rather than an impoundment. Nothing formal is recorded here: no ramp, no car park, no marked path. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Local rules can differ across the county line, so check where you stand. Barbless rules turn up on managed water more often than not. Lac Johnson at 1.7 km is the sensible second choice. Confirm access to Lac Boy locally before you travel.
