491-acre lake in Nipissing District, Ontario. The lake tops out around 63 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Spawning Lake runs 492 acres with 7.7 miles of edge, broken up by an island. That shoreline is heavily fingered (development index 2.5) — bays, points and pockets everywhere, which multiplies the fishable edge. About 30% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The basin spans about 2.1 mi end to end and 0.9 mi across at its widest. The water lies in Nipissing District. The nearest mapped water is McLaren Lake, 1 mi to the east.
In spring, lake trout run shallow here, mostly 10 to 40 ft. Summer pushes them deeper, 19 to 63 ft, and winter fish settle into 16 to 63 ft. Deep basin is the standout, a deep basin at roughly 54 ft, rated prime for summer lake trout. Time it for early morning. You won't need more than a white tube jig (deep) or a magnum spoon on downrigger most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (16 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 19 to 63 ft | dawn | Deep basin (54 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (16 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 16 to 63 ft | dawn | Deep basin (54 ft) | White tube jig, Airplane jig |
Spring lake whitefish on Spawning Lake hold shallow, usually 15 to 45 ft. By summer they slide out to 19 to 63 ft, and by winter most fish are in 19 to 63 ft. The chart's best answer is Deep basin — deep basin, 54 ft, prime for summer. Prime time lands in early morning. The summer box starts with a blade bait vertical or a small jigging spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (28 ft) | Small jig + waxworm, Blade bait (small) |

| Winter | 19 to 63 ft | midday & dawn | Deep basin (54 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
When the water first warms, walleye slide up into 4 to 15 ft. Summer is a 15 to 35 ft game here, winter a 20 to 40 ft one. Start at Break off the point. It's a drop-off holding about 28 ft of water and rates prime come fall. The feeding windows run the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (16 ft) | 1/8 oz jig + minnow, Hair jig |

When the water first warms, yellow perch slide up into 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 15 to 35 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 6 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
