Heavy overcast holding through the day, with hardly a ripple anywhere with the glass holding level. Activity on Lac Joachim should centre on the seam between weed and open water. Expect the better fishing from night into morning. Give the likely spots time before moving. Shortening days concentrate the feeding into fewer hours.

Lac Joachim is one of the Mauricie listings for Quebec. Mixed forest runs right down to the water. The water covers some 42 hectares, so pick a bank rather than trying to cover it all. Some 6.5 km of bank gives room to move when the wind turns. On our Mauricie list it sits near the top for size. Nearest town is La Tuque, 47 km off. Weymontachie is 72 km and Manawan 76 km. No boundary runs near, so the local rules hold throughout.
Open data we checked carries no depth for this water. A natural lake fishes on cover, and cover here means weed and timber. On a natural lake the weed line and the shelf beyond it do the work. Public occurrence data for Mauricie names northern pike, brook trout, walleye and yellow perch. It is the county picture; the agency list is water-specific. Lac Joachim gives up its fish to patience rather than distance.
Seasonal averages run from -16°C in January up to 17°C in July. Winter shuts things down for a spell, then spring reopens them fast. The lid usually sets by midwinter and gives way around early May. Ice usually gives way near early May, and forms again about mid November. The shoulder weeks of the open season are the productive ones. Lac Joachim runs to its own calendar within the local pattern.
Nothing we hold confirms whether access is permitted. It formed naturally, so levels move with rainfall rather than with a gate. No slipway, car park or made path shows up nearby in mapping, so treat access as rough. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Look for a notice board at the entrance. Access can change hands, so last year's answer may not hold. Lac Serpent at 1.5 km is the sensible second choice. Treat Lac Joachim as unsettled until someone local tells you otherwise.
