211-acre lake in Algoma District, Ontario. The lake tops out around 93 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. What follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Airport Lake runs 212 acres with 6.1 miles of edge. With a shoreline index of 3, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 30% of the water is 15 ft or less as modeled, the band where the food chain lives. The basin spans about 2 mi end to end and 0.5 mi across at its widest. The water lies in Algoma District. For a second option, Gervais L. 78 lies 2 mi southwest.
Start shallow in spring: lake trout sit in 10 to 40 ft that time of year. Summer pushes them deeper, 28 to 93 ft, and winter fish settle into 20 to 80 ft. The spot to know is Deep basin, a deep basin in about 79 ft of water that rates prime for lake trout in summer. Warm-month bites cluster around early morning. Throw a white tube jig (deep) or a magnum spoon on downrigger until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (23 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 28 to 93 ft | dawn | Deep basin (79 ft) | White tube jig (deep), Magnum spoon on downrigger |

Start shallow in spring: burbot sit in 25 to 70 ft that time of year. Summer pushes them deeper, 28 to 93 ft, and winter fish settle into 15 to 60 ft. The spot to know is Deep basin, a deep basin in about 79 ft of water that rates prime for burbot in summer. Warm-month bites cluster around after dark and midday. Throw a heavy jig + cut bait until the fish tell you otherwise.
