71-acre lake in Sudbury District, Ontario. The lake tops out around 9 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 the data behind the map says about each species, season by season:
The outline encloses 71 acres, worked by 1.6 miles of shoreline. The basin is a simple one (shoreline index 1.4) — close to a bowl, so the structure on the chart matters more than the bank. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. Call it 0.6 mi long by 0.3 mi wide at the broadest reach. Sudbury District claims this one. If the bite dies, Hanna Lake is 1 mi to the west.
The spring pattern is a shallow one: walleye in 2 to 9 ft. The depth story barely changes: 3 to 9 ft through summer, 3 to 9 ft in winter. Top water on the chart: Break off the point, a drop-off in the 4 ft range, prime in fall. 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 | 2 to 9 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 3 to 9 ft | dusk & dawn | Break off the point (4 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 3 to 9 ft | dusk & night | Break off the point (4 ft) | Jigging rap, Jig + big minnow |
| Winter | 3 to 9 ft | dusk & dawn | Deep basin (8 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, yellow perch run shallow here, mostly 2 to 9 ft. Summer keeps them at 3 to 9 ft, and they winter in 3 to 9 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring 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 | 2 to 9 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 3 to 9 ft | dawn | Deep basin (8 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 3 to 9 ft | midday | Deep basin (8 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 3 to 9 ft | midday & dawn | Deep basin (8 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 3 to 9 ft, then a winter hold in 3 to 9 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 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 (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 3 to 9 ft | dawn & dusk | Shallow bay flat (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 3 to 9 ft | midday & dawn | Shallow bay flat (3 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 3 to 9 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Early season smallmouth bass use the shallows, holding in 2 to 9 ft. Even in summer they hold at 3 to 9 ft; winter keeps them in 3 to 9 ft. Put Main-lake point first on the milk run — a point near 8 ft that grades prime for fall. In summer the feeding windows fall in early morning and the evening. Tie on a drop shot (goby/minnow) or a ned rig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 9 ft | dawn & dusk | Main-lake point (8 ft) | Ned rig, Tube jig |
| Summer | 3 to 9 ft | dawn & dusk | Break off the point (4 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 3 to 9 ft | midday & dawn | Main-lake point (8 ft) | Jerkbait, Blade bait |
| Winter | 3 to 9 ft | midday | Break off the point (4 ft) | Blade bait, Hair jig |
In spring, pumpkinseed run shallow here, mostly 1 to 8 ft. Midsummer fish sit out in 2 to 9 ft before dropping to 3 to 9 ft for winter. Spring pumpkinseed concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a micro tube or a sponge spider (fly) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 9 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 3 to 9 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 3 to 9 ft | dawn | Shallow bay flat (3 ft) | Tungsten ice jig + plastic, Tiny spoon |
Early season brown bullhead use the shallows, holding in 2 to 8 ft. Summer is a 2 to 9 ft game here, winter a 3 to 9 ft one. The chart's best answer is Deep basin — deep basin, 8 ft, prime for winter. Best bite is after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (3 ft) | |
| Summer | 2 to 9 ft | night & dusk | Shallow bay flat (3 ft) | |
| Fall | 3 to 9 ft | dusk | Deep basin (8 ft) | |
| Winter | 3 to 9 ft | midday | Deep basin (8 ft) |
