1,506-acre lake in Sudbury District, Ontario. The lake tops out around 53 ft. The depth data here comes from the Ontario MNRF survey of 1980 (a transect sounding survey). The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Carty Lake runs 1,513 acres with 23.3 miles of edge, broken up by 18 islands. With a shoreline index of 4.3, this water is all arms and coves — edge habitat well beyond its acreage. 56% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 3.6 mi with a 2.1-mi widest point. You'll find it in Sudbury District. For a second option, Harold Lake lies 2 mi southwest.
Spring lake whitefish on Carty Lake hold shallow, usually 15 to 45 ft. They move out to 16 to 53 ft in summer and finish the year down in 16 to 53 ft. Put Deep basin first on the milk run — a deep basin near 53 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 | Shallow feeding flat (18 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 16 to 53 ft | dawn | Deep basin (53 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (1 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 16 to 53 ft | midday & dawn | Deep basin (53 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
When the water first warms, walleye slide up into 4 to 15 ft. By summer they slide out to 15 to 35 ft, and by winter most fish are in 20 to 40 ft. If you only fish one area, make it Break off the point: a drop-off around 1 ft that scores good in fall. In summer the feeding windows fall in 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 (1 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Shallow feeding flat (18 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (1 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Deep basin (53 ft) | Jigging spoon + minnow head, Rattle bait |
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 1 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 (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shallow feeding flat (18 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (53 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Shallow feeding flat (18 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 Shallow bay flat, a weed flat in about 1 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 | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow feeding flat (18 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow feeding flat (18 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (1 ft) | Tip-ups, Large jigging spoon |
In spring, burbot run shallow here, mostly 16 to 53 ft. Summer keeps them at 16 to 53 ft, and they winter in 13 to 53 ft. Spring burbot concentrate at Deep basin, a prime-rated deep basin around 53 ft. Fish it in after dark and midday and you'll meet the bite. You won't need more than a heavy jig + cut bait most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 16 to 53 ft | night & dusk | Deep basin (53 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 16 to 53 ft | night & midday | Deep basin (53 ft) | Heavy jig + cut bait |
| Fall | 16 to 53 ft | night & dusk | Deep basin (53 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 13 to 53 ft | night & dusk | Deep basin (53 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
