227-acre lake in Nipissing District, Ontario. The lake tops out around 67 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. Here's the year, species by species, as the scoring engine sees it.
On the chart, Vireo Lake draws 231 acres inside 6.3 miles of shoreline — one island included. With a shoreline index of 2.9, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 49% of the surface on the model — that's where the groceries are. Tip to tip the water measures near 2.1 mi with a 0.5-mi widest point. You'll find it in Nipissing District. Closest neighbour on DepthScout: Roundbush Lake, 2 mi south of here.
In spring, lake trout run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 20 to 67 ft before dropping to 17 to 67 ft for winter. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 57 ft. Fish it in early morning and you'll meet the bite. 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 (17 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 20 to 67 ft | dawn | Deep basin (57 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (17 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 17 to 67 ft | dawn | Deep basin (57 ft) | White tube jig, Airplane jig |
When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 15 to 35 ft one. Start at Shallow bay flat. It's a weed flat holding about 6 ft of water and rates prime come spring. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (30 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (30 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (30 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts brown bullhead in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 3 to 12 ft; cold water stacks them in 10 to 25 ft. Shallow bay flat is the standout, a weed flat at roughly 6 ft, rated prime for spring brown bullhead. Plan around after dark and the evening in the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (6 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (6 ft) | |
| Fall | 5 to 15 ft | dusk | Shallow bay flat (6 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (57 ft) |
