229-acre lake in Sudbury 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. Species by species, here's what the data says the year looks like.
The outline encloses 229 acres, worked by 3.7 miles of shoreline. A middling shoreline index (1.7) gives it some bays to work without being a maze. The basin spans about 1 mi end to end and 0.6 mi across at its widest. Sudbury District claims this one. Its nearest charted neighbour, Ferris Lake, is 3 mi to the east.
In spring, lake whitefish run shallow here, mostly 9 to 30 ft. Summer keeps them at 9 to 30 ft, and they winter in 9 to 30 ft. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 15 ft. Fish it in early morning and you'll meet the bite. You won't need more than a blade bait vertical or a small jigging spoon most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 9 to 30 ft | midday & dawn | Break off the point (1 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 9 to 30 ft | dawn | Deep basin (15 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 | 9 to 30 ft | midday & dawn | Deep basin (15 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
The spring pattern is a shallow one: walleye in 4 to 15 ft. As the season builds they drop to 9 to 30 ft, wintering in 9 to 30 ft. Top water on the chart: Deep basin, a deep basin in the 15 ft range, prime in winter. Time it for the evening and early morning. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (2 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 9 to 30 ft | dusk & dawn | Deep basin (15 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 9 to 30 ft | dusk & night | Deep basin (15 ft) | Jigging rap, Jig + big minnow |
| Winter | 9 to 30 ft | dusk & dawn | Deep basin (15 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 9 to 30 ft. Deep basin is the standout, a deep basin at roughly 15 ft, rated prime for fall yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| 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 (15 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 9 to 30 ft | midday | Deep basin (15 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 9 to 30 ft | midday & dawn | Deep basin (15 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season northern pike use the shallows, holding in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 1 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| 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 bay flat (1 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Deep basin (15 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 |
