109-acre lake in Algoma District, Ontario. The lake tops out around 60 ft. The depth data here comes from the Ontario MNRF survey of 1966, a decades-old survey (a transect sounding survey). Species by species, here's what the data says the year looks like.
Dobie Lake maps at 109 acres behind 2.5 miles of shoreline. A middling shoreline index (1.7) gives it some bays to work without being a maze. The shallow band under 15 ft claims about 28% of the surface — that's where the groceries are. Figure 1 mi of water from one end to the other, 0.3 mi at the beam. It sits in Algoma District. Its nearest charted neighbour, Dry Fly Lake, is 1 mi to the northeast.
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 27 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 (12 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (27 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |

Early season lake trout use the shallows, holding in 10 to 40 ft. Expect a summer slide to 18 to 60 ft, then a winter hold in 15 to 60 ft. Put Deep basin first on the milk run — a deep basin near 58 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
