479-acre lake in Algoma District, Ontario. The lake tops out around 39 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from a transect sounding survey by the Ontario MNRF. The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Caribou Lake runs 481 acres with 4.6 miles of edge. Index 1.5 on the shoreline: a few honest points and pockets, nothing labyrinthine. The shallow band under 15 ft claims about 37% of the surface — that's where the groceries are. Figure 1.5 mi of water from one end to the other, 0.9 mi at the beam. The water lies in Algoma District. The nearest mapped water is Copp Lake, 2 mi to the west.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.

When the water first warms, lake whitefish slide up into 12 to 39 ft. There's no big seasonal slide here — summer means 12 to 39 ft, winter 12 to 39 ft. If you only fish one area, make it Deep basin: a deep basin around 39 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 12 to 39 ft chart-limited; documented 15 to 45 ft | midday & dawn | Break off the point (13 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 12 to 39 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (39 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (13 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 12 to 39 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (39 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
When the water first warms, cisco (lake herring) slide up into 10 to 39 ft. There's no big seasonal slide here — summer means 12 to 39 ft, winter 12 to 39 ft. If you only fish one area, make it Deep basin: a deep basin around 39 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a vertical flutter spoon (small) or a drop-shot micro plastic rigged through the warm months.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 39 ft chart-limited; documented 10 to 40 ft | dawn & dusk | Deep basin (39 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 12 to 39 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (39 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (13 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 12 to 39 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (39 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Early season walleye use the shallows, holding in 4 to 15 ft. Summer is a 15 to 35 ft game here, winter a 12 to 39 ft one. The chart's best answer is Break off the point — drop-off, 13 ft, prime for fall. Best bite is 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 (7 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Secondary point (19 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 39 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (13 ft) | Jigging rap, Jig + big minnow |

Spring yellow perch on Caribou Lake hold shallow, usually 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 15 to 35 ft. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Prime time lands in 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 (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (13 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (13 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (39 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning and the evening. 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 (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (13 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Back-bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Back-bay flat (6 ft) | Tip-ups, Large jigging spoon |
Spring puts smallmouth bass in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 12 to 39 ft. Fall smallmouth bass concentrate at Secondary point, a prime-rated point around 19 ft. Warm-month bites cluster around early morning and the evening. A drop shot (goby/minnow) or a ned rig covers the summer program.
