421-acre lake in Algoma District, Ontario. The lake tops out around 92 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 depth data here comes from the Ontario MNRF survey of 1978, a decades-old survey (an MNRF lake survey). What the data behind the map says about each species, season by season:
The outline encloses 422 acres, worked by 8.6 miles of shoreline. The 3 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Roughly 62% of the water is 15 ft or less, the band where the food chain lives. Figure 2.3 mi of water from one end to the other, 0.8 mi at the beam. Algoma District claims this one. Its nearest charted neighbour, Longhaul Lake, is 3 mi to the northeast.
Early season lake trout use the shallows, holding in 10 to 40 ft. Summer is a 28 to 92 ft game here, winter a 20 to 80 ft one. The chart's best answer is Deep basin — deep basin, 71 ft, prime for summer. Best bite is early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
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 | 10 to 40 ft | dawn & dusk | Main-lake point (1 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 28 to 92 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (71 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (1 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (71 ft) | White tube jig, Airplane jig |
Spring puts lake whitefish in skinny water — 15 to 45 ft is the zone. Warm water sends them out to 40 to 90 ft; cold water stacks them in 25 to 70 ft. Deep basin is the standout, a deep basin at roughly 71 ft, rated prime for summer lake whitefish. Plan around early morning in the warm months. A blade bait vertical or a small jigging spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Shallow feeding flat (15 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 40 to 90 ft | dawn | Deep basin (71 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (1 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Deep basin (71 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 15 to 35 ft. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 1 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shallow feeding flat (15 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (1 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Shallow feeding flat (15 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season burbot use the shallows, holding in 25 to 70 ft. Summer is a 28 to 92 ft game here, winter a 15 to 60 ft one. The chart's best answer is Deep basin — deep basin, 71 ft, prime for summer. Best bite is after dark and midday. Tie on a heavy jig + cut bait and you're in the game.
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 | 25 to 70 ft | night & dusk | Deep basin (71 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 28 to 92 ft chart-limited; documented 50 to 120 ft | night & midday | Deep basin (71 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Deep basin (71 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Deep basin (71 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
7 pieces of structure are mapped here — Deep basin, around 71 ft, is the deepest of them.
