422-acre lake in Timiskaming District, Ontario. The lake tops out around 26 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. What follows comes from the same scoring engine that paints the spots above.
The outline encloses 421 acres, worked by 11.5 miles of shoreline — 6 islands included. A development index of 4 means a maze of bays and points: far more casting targets than a round bowl of the same size. The shallow band under 15 ft claims about 77% of the surface on the model — that's where the groceries are. Tip to tip the water measures near 2.1 mi with a 1.1-mi widest point. It sits in Timiskaming District. Its nearest charted neighbour, Jackson Lake, is 1 mi to the northwest.
Start shallow in spring: lake whitefish sit in 8 to 26 ft that time of year. They don't go far with the seasons — 8 to 26 ft covers summer, 8 to 26 ft covers winter. The spot to know is Deep basin, a deep basin in about 22 ft of water that rates prime for lake whitefish in summer. Warm-month bites cluster around early morning. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 26 ft | midday & dawn | open water | Small jig + waxworm, Blade bait (small) |
| Summer | 8 to 26 ft | dawn | Deep basin (22 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 7 to 26 ft | dusk | Main-lake point (8 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 8 to 26 ft | midday & dawn | Deep basin (22 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Start shallow in spring: cisco (lake herring) sit in 7 to 26 ft that time of year. They don't go far with the seasons — 8 to 26 ft covers summer, 8 to 26 ft covers winter. The spot to know is Deep basin, a deep basin in about 22 ft of water that rates prime for cisco (lake herring) in spring. Warm-month bites cluster around early morning. Throw a vertical flutter spoon (small) or a drop-shot micro plastic until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 7 to 26 ft | dawn & dusk | Deep basin (22 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 8 to 26 ft | dawn | Deep basin (22 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | open water | Small casting spoon, Inline spinner (silver) |
| Winter | 8 to 26 ft | dawn | Deep basin (22 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
In spring, walleye run shallow here, mostly 4 to 15 ft. Midsummer fish sit out in 8 to 26 ft before dropping to 8 to 26 ft for winter. Winter walleye concentrate at Deep basin, a prime-rated deep basin around 22 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 8 to 26 ft | dusk & dawn | Main-lake point (8 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 8 to 26 ft | dusk & night | Main-lake point (8 ft) | Jigging rap, Jig + big minnow |
| Winter | 8 to 26 ft | dusk & dawn | Deep basin (22 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 8 to 26 ft before dropping to 8 to 26 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 8 to 26 ft | dawn | Deep basin (22 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 8 to 26 ft | midday | Deep basin (22 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 8 to 26 ft | midday & dawn | Deep basin (22 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, northern pike slide up into 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Main-lake point (8 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
