488-acre lake in Sudbury District, Ontario. The lake tops out around 38 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. Here's the year, species by species, as the scoring engine sees it.
The outline encloses 491 acres, worked by 12.4 miles of shoreline, broken up by 2 islands. That shoreline is heavily fingered (development index 4) — bays, points and pockets everywhere, which multiplies the fishable edge. The shallow band under 15 ft claims about 94% of the surface — that's where the groceries are. Tip to tip the water measures near 3 mi with a 1.1-mi widest point. It sits in Sudbury District. Its nearest charted neighbour, Portal Lake, is 2 mi to the southwest.
The spring pattern is a shallow one: lake whitefish in 11 to 38 ft. The depth story barely changes: 11 to 38 ft through summer, 11 to 38 ft in winter. Top water on the chart: Deep basin, a deep basin in the 29 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 | 11 to 38 ft | midday & dawn | Break off the point (1 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 11 to 38 ft | dawn | Deep basin (29 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 | 11 to 38 ft | midday & dawn | Deep basin (29 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 15 to 35 ft; cold water stacks them in 11 to 38 ft. Deep basin is the standout, a deep basin at roughly 29 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 | 15 to 35 ft | dusk & dawn | Deep basin (29 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 11 to 38 ft | dusk & night | Deep basin (29 ft) | Jigging rap, Jig + big minnow |
| Winter | 11 to 38 ft | dusk & dawn | Deep basin (29 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 15 to 35 ft. Top water on the chart: Deep basin, a deep basin in the 29 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 (29 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (29 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (29 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 bay flat (1 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 |
