372-acre lake in Ontario. The lake tops out around 11 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. Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 372 acres wrapped in 4.6 miles of bank. With a 1.7 development index there's bank structure worth casting at, in moderation. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Tip to tip the water measures near 1.7 mi with a 0.7-mi widest point. Ottawa claims this one. If the bite dies, Rideau Canal (Ottawa) is 14 mi to the east.
Spring puts walleye in skinny water — 3 to 11 ft is the zone. Summer fish stay in 3 to 11 ft, and winter fish hold in 3 to 11 ft. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 5 ft. Warm-month bites cluster around the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) 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 11 ft chart-limited; documented 4 to 15 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 3 to 11 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (5 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 3 to 11 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (5 ft) | Jigging rap, Jig + big minnow |
| Winter | 3 to 11 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (9 ft) | Jigging spoon + minnow head, Rattle bait |
Start shallow in spring: yellow perch sit in 3 to 11 ft that time of year. They don't go far with the seasons — 3 to 11 ft covers summer, 3 to 11 ft covers winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.

| Spring | 3 to 11 ft chart-limited; documented 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 3 to 11 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (9 ft) | Drop-shot micro plastics, Small spoon tipped with worm |

| Winter | 3 to 11 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (9 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. Expect a summer slide to 3 to 11 ft, then a winter hold in 3 to 11 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.

| 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 | 3 to 11 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Shallow bay flat (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 3 to 11 ft chart-limited; documented 6 to 18 ft | midday & dawn | Shallow bay flat (3 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 3 to 11 ft chart-limited; documented 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Come spring, look for smallmouth bass tight to the bank in 3 to 11 ft. Through summer count on 3 to 11 ft; the winter hold is 3 to 11 ft. Start at Main-lake point. It's a point holding about 8 ft of water and rates prime come fall. Prime time lands in early morning and the evening. A drop shot (goby/minnow) or a ned rig is the honest summer answer here.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 11 ft chart-limited; documented 3 to 12 ft | dawn & dusk | Main-lake point (8 ft) | Ned rig, Tube jig |
| Summer | 3 to 11 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Break off the point (5 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 3 to 11 ft chart-limited; documented 8 to 25 ft | midday & dawn | Main-lake point (8 ft) | Jerkbait, Blade bait |
| Winter | 3 to 11 ft chart-limited; documented 20 to 45 ft | midday | Break off the point (5 ft) | Blade bait, Hair jig |
When the water first warms, largemouth bass slide up into 2 to 10 ft. By summer they slide out to 3 to 11 ft, and by winter most fish are in 3 to 11 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a texas-rigged 10" worm or a deep-diving crankbait rigged through the warm months.

The spring pattern is a shallow one: rock bass in 2 to 10 ft. Midsummer fish sit out in 3 to 11 ft before dropping to 3 to 11 ft for winter. The spot to know is Main-lake point, a point in about 8 ft of water that rates prime for rock bass in summer. Plan around the evening in the warm months. Summer baits: a ned rig (small) or a marabou jig gets it done.

Constance Lake is about 11 ft (3 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target walleye, yellow perch, northern pike, smallmouth bass, largemouth bass, rock bass, crappie, pumpkinseed, brown bullhead, channel catfish, common carp on Constance Lake.
Break off the point is the top-rated area: a drop-off in about 5 ft of water that rates prime for walleye in fall. The map above holds the full rated-spot list for every species and season.
For walleye, the summer bite is best in the evening and early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
