791-acre lake in Sudbury District, Ontario. The lake tops out around 85 ft. The depth data here comes from the Ontario MNRF survey of 1980 (a transect sounding survey). The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 795 acres wrapped in 18.6 miles of bank, with 30 islands in the mix. With a shoreline index of 4.7, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 48% of the surface — that's where the groceries are. Call it 2.9 mi long by 1.5 mi wide at the broadest reach. Sudbury District claims this one. If the bite dies, Lonely Lake is 3 mi to the southeast.
Early season brook trout use the shallows, holding in 2 to 15 ft. Summer is a 10 to 30 ft game here, winter a 3 to 20 ft one. The chart's best answer is Main-lake point — point, 1 ft, prime for spring. Best bite is early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (1 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (1 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (1 ft) | Small jigging spoon, Tungsten jig + plastic |
When the water first warms, lake trout slide up into 10 to 40 ft. Summer is a 26 to 85 ft game here, winter a 20 to 80 ft one. Start at Deep basin. It's a deep basin holding about 85 ft of water and rates prime come summer. The feeding windows run early morning. Keep a white tube jig (deep) or a magnum spoon on downrigger rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (46 ft) | Casting spoon over shoals, Jerkbait (shallow) |

In spring, walleye run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 15 to 35 ft, and winter fish settle into 20 to 40 ft. Break off the point is the standout, a drop-off at roughly 46 ft, rated prime for fall walleye. Time it for the evening and early morning. 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 (1 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Shallow feeding flat (23 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (46 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Break off the point (46 ft) | Jigging spoon + minnow head, Rattle bait |

Top water on the chart: Shallow bay flat, a weed flat in the 1 ft range, prime in spring. Time it for early morning. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.

|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
