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.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 30 ft chart-limited; documented 10 to 40 ft | dawn & dusk | Break off the point (9 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 9 to 30 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (20 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 6 to 30 ft chart-limited; documented 10 to 50 ft | dusk & dawn | Break off the point (9 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 8 to 30 ft chart-limited; documented 20 to 80 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.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 9 to 30 ft chart-limited; documented 15 to 45 ft | midday & dawn | Break off the point (9 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 9 to 30 ft chart-limited; documented 40 to 90 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 chart-limited; documented 25 to 70 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.
