569-acre lake in Thunder Bay District, Ontario. The lake tops out around 33 ft. The depth data here comes from the Ontario MNRF survey of 1986 (a transect sounding survey). Here is how the season plays out for each species, straight from the data behind the map.
The outline encloses 571 acres, worked by 20.9 miles of shoreline, broken up by 24 islands. With a shoreline index of 6.2, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 94% of the surface — that's where the groceries are. The basin spans about 2 mi end to end and 1.8 mi across at its widest. It sits in Thunder Bay District. If the bite dies, Majata Lake is 7 mi to the east.
The spring pattern is a shallow one: lake whitefish in 10 to 33 ft. The depth story barely changes: 10 to 33 ft through summer, 10 to 33 ft in winter. Top water on the chart: Deep basin, a deep basin in the 31 ft range, prime in summer. Time it for early morning. Summer baits: a blade bait vertical or a small jigging spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 33 ft | midday & dawn | Shallow feeding flat (17 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 10 to 33 ft | dawn | Deep basin (31 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 | 10 to 33 ft | midday & dawn | Deep basin (31 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Spring puts walleye in skinny water — 4 to 15 ft is the zone. Warm water sends them out to 10 to 33 ft; cold water stacks them in 10 to 33 ft. Deep basin is the standout, a deep basin at roughly 31 ft, rated prime for winter walleye. Plan around the evening and early morning in the warm months. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (1 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 10 to 33 ft | dusk & dawn | Deep basin (31 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 10 to 33 ft | dusk & night | Deep basin (31 ft) | Jigging rap, Jig + big minnow |
| Winter | 10 to 33 ft | dusk & dawn | Deep basin (31 ft) | Jigging spoon + minnow head, Rattle bait |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 10 to 33 ft. Top water on the chart: Deep basin, a deep basin in the 31 ft range, prime in fall. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| 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 | Deep basin (31 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 10 to 33 ft | midday | Deep basin (31 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 10 to 33 ft | midday & dawn | Deep basin (31 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. They move out to 8 to 20 ft in summer and finish the year down in 5 to 15 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 1 ft that scores prime in spring. Best bite is early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow feeding flat (17 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow feeding flat (17 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow feeding flat (17 ft) | Tip-ups, Large jigging spoon |
The spring pattern is a shallow one: rock bass in 2 to 10 ft. As the season builds they drop to 5 to 20 ft, wintering in 12 to 30 ft. Top water on the chart: Deep basin, a deep basin in the 31 ft range, prime in winter. Time it for the evening. Summer baits: a ned rig (small) or a marabou jig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Main-lake point (1 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 20 ft | dusk | Main-lake point (1 ft) | Ned rig (small), Marabou jig |
| Fall | 8 to 22 ft | midday | Break off the point (1 ft) | Small tube jig, Inline spinner |
| Winter | 12 to 30 ft | midday | Deep basin (31 ft) | Tungsten jig + plastic, Small spoon + spike |
Come spring, look for burbot tight to the bank in 10 to 33 ft. Through summer count on 10 to 33 ft; the winter hold is 8 to 33 ft. Start at Deep basin. It's a deep basin holding about 31 ft of water and rates prime come spring. Prime time lands in after dark and midday. A heavy jig + cut bait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 33 ft | night & dusk | Deep basin (31 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
