63-acre lake in Thunder Bay District, Ontario. The lake tops out around 40 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 64 acres wrapped in 1.9 miles of bank. A middling shoreline index (1.7) gives it some bays to work without being a maze. The shallow band under 15 ft claims about 33% of the surface — that's where the groceries are. The basin spans about 0.7 mi end to end and 0.2 mi across at its widest. Thunder Bay District claims this one. Its nearest charted neighbour, Dunc Lake, is 2 mi to the west.
Spring northern pike on Deer Lake hold shallow, usually 2 to 8 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 5 to 15 ft. The chart's best answer is Shallow bay flat — weed flat, 7 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.

|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (7 ft) | #5 inline spinner, Spoon (red/white) |

Early season burbot use the shallows, holding in 12 to 40 ft. Even in summer they hold at 12 to 40 ft; winter keeps them in 10 to 40 ft. The chart's best answer is Deep basin — deep basin, 38 ft, prime for spring. Best bite is after dark and midday. Tie on a heavy jig + cut bait and you're in the game.
