42-acre lake in Renfrew County, Ontario. The lake tops out around 33 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Below is the species-by-species picture, pulled from the same data the map uses.
Otter Lake maps at 43 acres behind 1.5 miles of shoreline. A middling shoreline index (1.6) gives it some bays to work without being a maze. Roughly 63% of the water is 15 ft or less as modeled, the band where the food chain lives. End to end it runs roughly 0.6 mi, about 0.2 mi across. Renfrew County claims this one. Carson Lake sits 1 mi west — the closest neighbouring chart.
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 10 to 33 ft. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 4 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
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 | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (28 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 10 to 33 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (28 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 10 to 33 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (28 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring northern pike on Otter Lake hold shallow, usually 2 to 8 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 5 to 15 ft. The chart's best answer is Shallow bay flat — weed flat, 4 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (4 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (15 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (15 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (4 ft) | Tip-ups, Large jigging spoon |
Spring smallmouth bass on Otter 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 10 to 33 ft. The chart's best answer is Main-lake point — point, 8 ft, prime for fall. Prime time lands in early morning and the evening. The summer box starts with a drop shot (goby/minnow) or a ned rig.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (8 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (15 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (8 ft) | Jerkbait, Blade bait |
| Winter | 10 to 33 ft chart-limited; documented 20 to 45 ft | midday | Break off the point (15 ft) | Blade bait, Hair jig |
Early season largemouth bass use the shallows, holding in 2 to 10 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 10 to 33 ft. Put Shallow bay flat first on the milk run — a weed flat near 4 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.

Spring puts pumpkinseed in skinny water — 1 to 8 ft is the zone. Warm water sends them out to 2 to 10 ft; cold water stacks them in 6 to 18 ft. Shallow bay flat is the standout, a weed flat at roughly 4 ft, rated prime for spring pumpkinseed. Plan around the evening and early morning in the warm months. A micro tube or a sponge spider (fly) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (4 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (4 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (4 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Shallow bay flat (4 ft) | Tungsten ice jig + plastic, Tiny spoon |
