137-acre lake in Sudbury District, Ontario. The lake tops out around 80 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. What the data behind the map says about each species, season by season:
Traced from the shoreline, Saw Lake runs 137 acres with 6 miles of edge, with 3 islands in the mix. That shoreline is heavily fingered (development index 3.7) — bays, points and pockets everywhere, which multiplies the fishable edge. 46% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The basin spans about 1.5 mi end to end and 0.6 mi across at its widest. You'll find it in Sudbury District. For a second option, Ivanhoe L. 9 lies 1 mi west.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Summer brook trout concentrate at Break off the point, a prime-rated drop-off around 30 ft. Warm-month bites cluster around early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (4 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (30 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (4 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (12 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, lake trout run shallow here, mostly 10 to 40 ft. Midsummer fish sit out in 24 to 80 ft before dropping to 20 to 80 ft for winter. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 76 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 | Break off the point (30 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 24 to 80 ft | dawn | Deep basin (76 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Break off the point (30 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (76 ft) | White tube jig, Airplane jig |
Spring lake whitefish on Saw Lake hold shallow, usually 15 to 45 ft. They move out to 24 to 80 ft in summer and finish the year down in 25 to 70 ft. Put Deep basin first on the milk run — a deep basin near 76 ft that grades prime for summer. The feeding windows run 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 (30 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 24 to 80 ft | dawn | Deep basin (76 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (30 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Deep basin (76 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Spring cisco (lake herring) on Saw Lake hold shallow, usually 10 to 40 ft. They move out to 40 to 80 ft in summer and finish the year down in 20 to 60 ft. Put Deep basin first on the milk run — a deep basin near 76 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a vertical flutter spoon (small) or a drop-shot micro plastic.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (30 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 40 to 80 ft | dawn | Deep basin (76 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (30 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Break off the point (30 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
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 12 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 (12 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) |
The spring pattern is a shallow one: northern pike in 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. The spot to know is Back-bay flat, a weed flat in about 2 ft of water that rates prime for northern pike in spring. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Back-bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (12 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (12 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (12 ft) | Tip-ups, Large jigging spoon |
