Rating depth structure for lake trout.

130-acre lake in Algoma District, Ontario. The lake tops out around 30 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
On the chart, Lower Shakwa Lake draws 130 acres inside 3.5 miles of shoreline. With a shoreline index of 2.2, this water is all arms and coves — edge habitat well beyond its acreage. About 91% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Tip to tip the water measures near 1.1 mi with a 0.4-mi widest point. You'll find it in Algoma District. The nearest mapped water is Shakwa Lake, 2 mi to the northwest.
The spring pattern is a shallow one: lake trout in 8 to 30 ft. The depth story barely changes: 9 to 30 ft through summer, 8 to 30 ft in winter. The spot to know is Deep basin, a deep basin in about 20 ft of water that rates prime for lake trout in summer. Plan around early morning in the warm months. Summer baits: a white tube jig (deep) or a magnum spoon on downrigger gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 30 ft | dawn & dusk | Break off the point (9 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 9 to 30 ft | dawn | Deep basin (20 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 6 to 30 ft | dusk & dawn | Break off the point (9 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 8 to 30 ft | dawn | Deep basin (20 ft) | White tube jig, Airplane jig |
Come spring, look for lake whitefish tight to the bank in 9 to 30 ft. Through summer count on 9 to 30 ft; the winter hold is 9 to 30 ft. If you only fish one area, make it Deep basin: a deep basin around 20 ft that scores prime in summer. Best bite is early morning. A blade bait vertical or a small jigging spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 9 to 30 ft | midday & dawn | Break off the point (9 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 9 to 30 ft | dawn | Deep basin (20 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (9 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 9 to 30 ft | midday & dawn | Deep basin (20 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
6 pieces of structure are mapped here — Deep basin, around 20 ft, is the deepest of them.
