479-acre lake in Algoma District, Ontario. The lake tops out around 90 ft. The depth data here comes from the Ontario MNRF survey of 1965, a decades-old survey (a transect sounding survey). Species by species, here's what the data says the year looks like.
On the chart, Gamitagama Lake draws 481 acres inside 13.1 miles of shoreline, with 15 islands in the mix. An index of 4.2 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. About 39% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 2.8 mi, about 1.3 mi across. You'll find it in Algoma District. The nearest mapped water is Dead Otter Lake, 2 mi to the southwest.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. The spot to know is Break off the point, a drop-off in about 9 ft of water that rates prime for brook trout in summer. Warm-month bites cluster around early morning and the evening. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (9 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (9 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |

Start shallow in spring: lake trout sit in 10 to 40 ft that time of year. Warm water sends them out to 27 to 90 ft; cold water stacks them in 20 to 80 ft. Top water on the chart: Deep basin, a deep basin in the 88 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a white tube jig (deep) or a magnum spoon on downrigger until the fish tell you otherwise.
