649-acre lake in Kenora District, Ontario. The lake tops out around 13 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 season-by-season read for each species follows, from the map's own numbers.
The outline encloses 652 acres, worked by 14.3 miles of shoreline, broken up by 15 islands. A development index of 4 means a maze of bays and points: far more casting targets than a round bowl of the same size. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Figure 3.7 mi of water from one end to the other, 0.9 mi at the beam. Kenora District claims this one. Bowcott Lake sits 15 mi southwest — the closest neighbouring chart.
Spring puts walleye in skinny water — 3 to 13 ft is the zone. Summer fish stay in 4 to 13 ft, and winter fish hold in 4 to 13 ft. Winter walleye concentrate at Deep basin, a prime-rated deep basin around 12 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 13 ft chart-limited; documented 4 to 15 ft | dusk & dawn | Main-lake point (3 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 4 to 13 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (3 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 4 to 13 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (3 ft) | Jigging rap, Jig + big minnow |
| Winter | 4 to 13 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (12 ft) | Jigging spoon + minnow head, Rattle bait |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 4 to 13 ft, and winter fish settle into 4 to 13 ft. The spot to know is Deep basin, a deep basin in about 12 ft of water that rates prime for yellow perch in fall. 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.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 4 to 13 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (12 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 4 to 13 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (12 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 4 to 13 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (12 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 4 to 13 ft, then a winter hold in 4 to 13 ft. Start at Shallow bay flat. It's a weed flat holding about 2 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.

Seach Lake is about 13 ft (4 m) deep at its deepest point. The depth data here comes from a transect sounding survey by the Ontario MNRF.
Anglers target walleye, yellow perch, northern pike on Seach 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.
Deep basin is the top-rated area: a deep basin in about 12 ft of water that rates prime for walleye in winter. 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.
