173-acre lake in Algoma District, Ontario. The lake tops out around 20 ft. The depth data here comes from the Ontario MNRF survey of 1964, a decades-old survey (a transect sounding survey). Below is the species-by-species picture, pulled from the same data the map uses.
On the chart, Leaf Lake draws 174 acres inside 4.3 miles of shoreline — one island included. That shoreline is heavily fingered (development index 2.3) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 73% of the water is 15 ft or less, the band where the food chain lives. Tip to tip the water measures near 1.2 mi with a 0.5-mi widest point. You'll find it in Algoma District. For a second option, Humberstone Lake lies 1 mi west.
When the water first warms, lake whitefish slide up into 6 to 20 ft. There's no big seasonal slide here — summer means 6 to 20 ft, winter 6 to 20 ft. Start at Deep basin. It's a deep basin holding about 20 ft of water and rates prime come summer. The feeding windows run early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 20 ft | midday & dawn | Break off the point (20 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 6 to 20 ft | dawn | Deep basin (20 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 5 to 20 ft | dusk | Break off the point (20 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 6 to 20 ft | midday & dawn | Deep basin (20 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Early season walleye use the shallows, holding in 4 to 15 ft. Expect a summer slide to 6 to 20 ft, then a winter hold in 6 to 20 ft. Put Break off the point first on the milk run — a drop-off near 20 ft that grades prime for fall. In summer the feeding windows fall in the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (2 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 6 to 20 ft | dusk & dawn | Break off the point (20 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 6 to 20 ft | dusk & night | Break off the point (20 ft) | Jigging rap, Jig + big minnow |
| Winter | 6 to 20 ft | dusk & dawn | Deep basin (20 ft) | Jigging spoon + minnow head, Rattle bait |
Spring yellow perch on Leaf Lake hold shallow, usually 3 to 12 ft. They move out to 6 to 20 ft in summer and finish the year down in 6 to 20 ft. Put Shallow bay flat first on the milk run — a weed flat near 4 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 6 to 20 ft | dawn | Deep basin (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 20 ft | midday | Deep basin (20 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 20 ft | midday & dawn | Deep basin (20 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 8 to 20 ft; cold water stacks them in 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 4 ft, rated prime for spring northern pike. Plan around early morning and the evening in the warm months. A bucktail or a weedless spoon over cabbage covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (4 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (20 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (4 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (4 ft) | Tip-ups, Large jigging spoon |
