219-acre lake in Rainy River District, Ontario. The lake tops out around 16 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Every species below gets its seasonal read from the same numbers driving the chart.
Little McCaulay Lake maps at 217 acres behind 4.3 miles of shoreline. A middling shoreline index (2.1) gives it some bays to work without being a maze. Roughly 89% of the water is 15 ft or less as modeled, the band where the food chain lives. Tip to tip the water measures near 1.1 mi with a 0.8-mi widest point. It sits in Rainy River District. Its nearest charted neighbour, Chub Lake, is 1 mi to the north.
The spring pattern is a shallow one: walleye in 4 to 15 ft. Midsummer fish sit out in 5 to 16 ft before dropping to 5 to 16 ft for winter. The spot to know is Break off the point, a drop-off in about 7 ft of water that rates prime for walleye in fall. Plan around the evening and early morning in the warm months. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
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 | 4 to 15 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 5 to 16 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (7 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 5 to 16 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (7 ft) | Jigging rap, Jig + big minnow |
| Winter | 5 to 16 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (14 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 5 to 16 ft before dropping to 5 to 16 ft for winter. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.

Early season northern pike use the shallows, holding in 2 to 8 ft. Summer is a 5 to 16 ft game here, winter a 5 to 15 ft one. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.

Deep basin is the standout, a deep basin at roughly 14 ft, rated prime for spring cisco (lake herring). Time it for early morning. You won't need more than a vertical flutter spoon (small) or a drop-shot micro plastic most summer days.
