Flat light and a covered sky today, with air barely moving and steady pressure. Start the search at Upper Boot Lake along inflow corners and shaded margins. Numbers are low everywhere; the morning is the pick of them. Go lighter and slower than usual. The autumn feed-up is on; baitfish areas are the key.

Upper Boot Lake is set in Sudbury, Ontario. Pine and birch runs right down to the water. The water covers some 39 hectares, so pick a bank rather than trying to cover it all. At about 5.6 km of edge, most people work one arm at a time. Dowling is the closest place, 99 km off. Beyond it, Rayside-Balfour at 102 km and Capreol at 107 km. No county line comes close, which keeps the paperwork simple.
The records we hold are silent on depth, so plan to find it yourself. Weed, then depth: that is the order to fish a water of this kind. Bays and points beat straight shoreline every time on water like this. Records held for Sudbury cover smallmouth bass, northern pike, yellow perch, Iowa darter and walleye. The county list is broader than any single water. Upper Boot Lake responds to conditions more than to tactics.
On the long-term average, July reads 17°C and January reads -16°C. Expect a real winter and a strong spring after it. Expect a solid lid for months and a thaw around late April. Averages suggest open water from about late April through to roughly late November. The middle of summer slows a little, with dawn and dusk carrying it. Upper Boot Lake runs to its own calendar within the local pattern.
Public data does not answer the access question here. It formed naturally, so levels move with rainfall rather than with a gate. Nothing formal is recorded here: no ramp, no car park, no marked path. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. A landowner's word beats anything printed elsewhere. Some water is controlled locally without a sign saying so. Failing this one, try Boot Lake, 2.2 km away. Signs at Upper Boot Lake carry more weight than any list.
