340-acre lake in Ontario. The lake tops out around 12 ft. The depth data here comes from the Ontario MNRF survey of 2006 (an MNRF lake survey). The rest of this page walks each species through its year, using the map's own scoring.
On the chart, Lake Laurentian draws 341 acres inside 11 miles of shoreline, with 7 islands in the mix. That shoreline is heavily fingered (development index 4.3) — bays, points and pockets everywhere, which multiplies the fishable edge. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Tip to tip the water measures near 1.5 mi with a 1-mi widest point. You'll find it in Greater Sudbury / Grand Sudbury. The nearest mapped water is Ramsey Lake, 2 mi to the north.
When the water first warms, pumpkinseed slide up into 1 to 8 ft. Summer is a 2 to 10 ft game here, winter a 4 to 12 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 the evening and early morning. Keep a micro tube or a sponge spider (fly) rigged through the warm months.
| 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 10 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 3 to 12 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 4 to 12 ft | dawn | Deep basin (12 ft) | Tungsten ice jig + plastic, Tiny spoon |
