135-acre lake in Algoma District, Ontario. The lake tops out around 66 ft. The depth data here comes from the Ontario MNRF survey of 1982 (a transect sounding survey). The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Rochester Lake runs 135 acres with 5.8 miles of edge, with 2 islands in the mix. An index of 3.6 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Littoral water — the productive band under ~15 ft — makes up 42% of this chart. Tip to tip the water measures near 2 mi with a 0.4-mi widest point. You'll find it in Algoma District. For a second option, Potbelly L. lies 1 mi southwest.
In spring, lake trout run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 20 to 66 ft before dropping to 17 to 66 ft for winter. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 65 ft. Fish it in early morning and you'll meet the bite. You won't need more than a white tube jig (deep) or a magnum spoon on downrigger most summer days.
