315-acre lake in Sudbury District, Ontario. The lake tops out around 59 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. What the data behind the map says about each species, season by season:
The drawn water covers 316 acres wrapped in 5.3 miles of bank — 9 islands included. With a 2.1 development index there's bank structure worth casting at, in moderation. Roughly 40% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 2 mi end to end and 0.5 mi across at its widest. Sudbury District claims this one. Its nearest charted neighbour, Middle Stetham Lake, is 2 mi to the south.
The spring pattern is a shallow one: lake whitefish in 15 to 45 ft. Midsummer fish sit out in 18 to 59 ft before dropping to 18 to 59 ft for winter. The spot to know is Deep basin, a deep basin in about 57 ft of water that rates prime for lake whitefish in summer. Plan around early morning in the warm months. Summer baits: a blade bait vertical or a small jigging spoon gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (23 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 18 to 59 ft | dawn | Deep basin (57 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (23 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 18 to 59 ft | midday & dawn | Deep basin (57 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Spring puts walleye in skinny water — 4 to 15 ft is the zone. As the season builds they drop to 15 to 35 ft, wintering in 20 to 40 ft. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 23 ft. Warm-month bites cluster around the evening and early morning. 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 | 15 to 35 ft | dusk & dawn | Break off the point (23 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (23 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Break off the point (23 ft) | Jigging spoon + minnow head, Rattle bait |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 15 to 35 ft. The spot to know is Break off the point, a drop-off in about 23 ft of water that rates prime for yellow perch in summer. Warm-month bites cluster around early morning. 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 | Break off the point (23 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (23 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (23 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Start at Shallow bay flat. It's a weed flat holding about 1 ft of water and rates prime come spring. Prime time lands in 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 | Break off the point (23 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (1 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (1 ft) | Tip-ups, Large jigging spoon |
