303-acre lake in Sudbury District, Ontario. The lake tops out around 70 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. The rest of this page walks each species through its year, using the map's own scoring.
Kerr Lake maps at 306 acres behind 7.1 miles of shoreline, with 2 islands in the mix. The 2.9 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 47% of this chart, as modeled. Figure 1.4 mi of water from one end to the other, 1 mi at the beam. It sits in Sudbury District. If the bite dies, McGuey Lake is 1 mi to the northeast.
Spring brook trout on Kerr Lake hold shallow, usually 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. The chart's best answer is Break off the point — drop-off, 32 ft, prime for summer. Prime time lands in early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (32 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (18 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for lake trout tight to the bank in 10 to 40 ft. Expect a summer slide to 21 to 70 ft, then a winter hold in 18 to 70 ft. Start at Deep basin. It's a deep basin holding about 60 ft of water and rates prime come summer. Prime time lands in early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (18 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 21 to 70 ft | dawn | Deep basin (60 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (18 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 18 to 70 ft | dawn | Deep basin (60 ft) | White tube jig, Airplane jig |
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 8 to 40 ft. Put Break off the point first on the milk run — a drop-off near 32 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (18 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (32 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (18 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (32 ft) | Jigging spoon, Tube jig (white) |
Spring puts walleye in skinny water — 4 to 15 ft is the zone. Warm water sends them out to 15 to 35 ft; cold water stacks them in 20 to 40 ft. Break off the point is the standout, a drop-off at roughly 32 ft, rated prime for fall walleye. Plan around the evening and early morning in the warm months. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (18 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (32 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (32 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Break off the point (32 ft) | Jigging spoon + minnow head, Rattle bait |
Come spring, look for burbot tight to the bank in 25 to 70 ft. Through summer count on 21 to 70 ft; the winter hold is 15 to 60 ft. Start at Deep basin. It's a deep basin holding about 60 ft of water and rates prime come spring. Prime time lands in after dark and midday. A heavy jig + cut bait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Deep basin (60 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 21 to 70 ft | night & midday | Deep basin (60 ft) | Heavy jig + cut bait |
| Fall | 21 to 70 ft | night & dusk | Deep basin (60 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Deep basin (60 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
