90-acre lake in Algoma District, Ontario. The lake tops out around 33 ft. The depth data here comes from the Ontario MNRF survey of 2023 (an MNRF lake survey). Every species below gets its seasonal read from the same numbers driving the chart.
Whitman Lake maps at 90 acres behind 3.6 miles of shoreline. With a shoreline index of 2.7, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 69% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 1.2 mi end to end and 0.4 mi across at its widest. It sits in Algoma District. Vixen Lake sits 1 mi southwest — the closest neighbouring chart.
When the water first warms, brook trout slide up into 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. If you only fish one area, make it Break off the point: a drop-off around 10 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (10 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |

Spring puts cisco (lake herring) in skinny water — 8 to 33 ft is the zone. Summer fish stay in 10 to 33 ft, and winter fish hold in 10 to 33 ft. Spring cisco (lake herring) concentrate at Deep basin, a prime-rated deep basin around 31 ft. Warm-month bites cluster around early morning. A vertical flutter spoon (small) or a drop-shot micro plastic covers the summer program.

|---|---|---|---|---|
| Spring | 8 to 33 ft | dawn & dusk | Deep basin (31 ft) | Small silver spoon, Tiny swim jig (white) |
