6,860-acre lake in Kenora District, Ontario. The lake tops out around 26 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 the Ontario MNRF survey of 1978, a decades-old survey (a transect sounding survey). Species by species, here's what the data says the year looks like.
Windsor Lake maps at 6,891 acres behind 105.3 miles of shoreline — 53 islands included. An index of 9 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. 95% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 8.1 mi, about 5 mi across. It sits in Kenora District. Its nearest charted neighbour, Justice Lake, is 7 mi to the north.
Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Warm water sends them out to 8 to 26 ft; cold water stacks them in 8 to 26 ft. Top water on the chart: Gravel shoal, a gravel shoal in the 6 ft range, prime in spring. Fish it in the evening and early morning and you'll meet the bite. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
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 | Gravel shoal (6 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 8 to 26 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Deep basin (26 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 8 to 26 ft chart-limited; documented 12 to 40 ft | dusk & night | Deep basin (26 ft) | Jigging rap, Jig + big minnow |
| Winter | 8 to 26 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (26 ft) | Jigging spoon + minnow head, Rattle bait |
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 8 to 26 ft; cold water stacks them in 8 to 26 ft. Deep basin is the standout, a deep basin at roughly 26 ft, rated prime for fall yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Weed flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 8 to 26 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (26 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 8 to 26 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (26 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 8 to 26 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (26 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring northern pike on Windsor Lake hold shallow, usually 2 to 8 ft. They move out to 8 to 20 ft in summer and finish the year down in 5 to 15 ft. Put Weed flat first on the milk run — a weed flat near 2 ft that grades prime for spring. The feeding windows run 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 | Weed flat (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow feeding flat (11 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shoreline point (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow feeding flat (11 ft) | Tip-ups, Large jigging spoon |
The spring pattern is a shallow one: lake sturgeon in 3 to 15 ft. Midsummer fish sit out in 8 to 26 ft before dropping to 8 to 26 ft for winter. The spot to know is Deep basin, a deep basin in about 26 ft of water that rates prime for lake sturgeon in fall. Plan around after dark and the evening in the warm months.

Structure-wise the chart holds 16 features, led in depth by Deep basin at roughly 26 ft.

Windsor Lake is about 26 ft (8 m) deep at its deepest point. The depth data here comes from the Ontario MNRF survey of 1978, a decades-old survey (a transect sounding survey).
Anglers target walleye, yellow perch, northern pike, lake sturgeon on Windsor Lake. This isn't a survey of the lake — none is on record for it — but an informed estimate from the species Ontario's MNRF recorded in the nearest surveyed lakes, filtered to this lake's depth and habitat.
Gravel shoal is the top-rated area: a gravel shoal in about 6 ft of water that rates prime for walleye in spring. Open the map above to see every rated spot for each 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.
