A grey, even sky over the water, with flat calm through the day with the glass holding level. Whatever swims in Lac du Castor should be near structure within a cast of the bank. Expectations low today; if anything moves, it will be in the night. Lower the pace and stay patient. Shortening days concentrate the feeding into fewer hours.

Lac du Castor falls in Abitibi-Témiscamingue, part of Quebec. It sits in lake country bush country. The water covers some 32 hectares, so pick a bank rather than trying to cover it all. A shoreline of some 4.1 km keeps the choices simple. Start from Saint-Isidore, 31 km down the road. It is 181 km to Greater Sudbury, the nearest city. This one is safely inside the county line.
Open data we checked carries no depth for this water. Read the surface for the wind lane, then fish the edge of it. Still water like this holds fish on the edges rather than out in the open. Public occurrence data for Abitibi-Témiscamingue names northern pike, yellow perch, walleye, white sucker and brown bullhead. Records at this level tell you what is in the area. Work Lac du Castor in sections rather than trying to cover it.
Seasonal averages run from -16°C in January up to 18°C in July. Fishing here follows the temperature more than the calendar. The lid usually goes in late April, which opens the strongest weeks of the year. From about late April to around late November, expect open water on the long-run figures. May into June fishes hardest, and September gives a second good stretch before the lid returns. The season on Lac du Castor rarely departs from it.
Our records carry no access rule either way. It formed naturally, so levels move with rainfall rather than with a gate. A pier 310 m from here gives a platform over deeper water. A wire trace and a big bright lure handle the pike; deep water asks for a heavier spoon. Bank access can be seasonal on ground like this. Night access is frequently treated as a separate matter. Failing this one, try Lac aux Pins, 2.6 km away. What applies at Lac du Castor may have changed since it was mapped.
